+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+Package spew implements a deep pretty printer for Go data structures to aid in
+debugging.
+
+A quick overview of the additional features spew provides over the built-in
+printing facilities for Go data types are as follows:
+
+	* Pointers are dereferenced and followed
+	* Circular data structures are detected and handled properly
+	* Custom Stringer/error interfaces are optionally invoked, including
+	  on unexported types
+	* Custom types which only implement the Stringer/error interfaces via
+	  a pointer receiver are optionally invoked when passing non-pointer
+	  variables
+	* Byte arrays and slices are dumped like the hexdump -C command which
+	  includes offsets, byte values in hex, and ASCII output (only when using
+	  Dump style)
+
+There are two different approaches spew allows for dumping Go data structures:
+
+	* Dump style which prints with newlines, customizable indentation,
+	  and additional debug information such as types and all pointer addresses
+	  used to indirect to the final value
+	* A custom Formatter interface that integrates cleanly with the standard fmt
+	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
+	  similar to the default %v while providing the additional functionality
+	  outlined above and passing unsupported format verbs such as %x and %q
+	  along to fmt
+
+Quick Start
+
+This section demonstrates how to quickly get started with spew.  See the
+sections below for further details on formatting and configuration options.
+
+To dump a variable with full newlines, indentation, type, and pointer
+information use Dump, Fdump, or Sdump:
+	spew.Dump(myVar1, myVar2, ...)
+	spew.Fdump(someWriter, myVar1, myVar2, ...)
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Alternatively, if you would prefer to use format strings with a compacted inline
+printing style, use the convenience wrappers Printf, Fprintf, etc with
+%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
+%#+v (adds types and pointer addresses):
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+Configuration Options
+
+Configuration of spew is handled by fields in the ConfigState type.  For
+convenience, all of the top-level functions use a global state available
+via the spew.Config global.
+
+It is also possible to create a ConfigState instance that provides methods
+equivalent to the top-level functions.  This allows concurrent configuration
+options.  See the ConfigState documentation for more details.
+
+The following configuration options are available:
+	* Indent
+		String to use for each indentation level for Dump functions.
+		It is a single space by default.  A popular alternative is "\t".
+
+	* MaxDepth
+		Maximum number of levels to descend into nested data structures.
+		There is no limit by default.
+
+	* DisableMethods
+		Disables invocation of error and Stringer interface methods.
+		Method invocation is enabled by default.
+
+	* DisablePointerMethods
+		Disables invocation of error and Stringer interface methods on types
+		which only accept pointer receivers from non-pointer variables.
+		Pointer method invocation is enabled by default.
+
+	* DisablePointerAddresses
+		DisablePointerAddresses specifies whether to disable the printing of
+		pointer addresses. This is useful when diffing data structures in tests.
+
+	* DisableCapacities
+		DisableCapacities specifies whether to disable the printing of
+		capacities for arrays, slices, maps and channels. This is useful when
+		diffing data structures in tests.
+
+	* ContinueOnMethod
+		Enables recursion into types after invoking error and Stringer interface
+		methods. Recursion after method invocation is disabled by default.
+
+	* SortKeys
+		Specifies map keys should be sorted before being printed. Use
+		this to have a more deterministic, diffable output.  Note that
+		only native types (bool, int, uint, floats, uintptr and string)
+		and types which implement error or Stringer interfaces are
+		supported with other types sorted according to the
+		reflect.Value.String() output which guarantees display
+		stability.  Natural map order is used by default.
+
+	* SpewKeys
+		Specifies that, as a last resort attempt, map keys should be
+		spewed to strings and sorted by those strings.  This is only
+		considered if SortKeys is true.

+Simply call spew.Dump with a list of variables you want to dump:
+
+	spew.Dump(myVar1, myVar2, ...)
+
+You may also call spew.Fdump if you would prefer to output to an arbitrary
+io.Writer.  For example, to dump to standard error:
+
+	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
+
+A third option is to call spew.Sdump to get the formatted output as a string:
+
+	str := spew.Sdump(myVar1, myVar2, ...)
+
+Sample Dump Output
+
+See the Dump example for details on the setup of the types and variables being
+shown here.
+
+	(main.Foo) {
+	 unexportedField: (*main.Bar)(0xf84002e210)({
+	  flag: (main.Flag) flagTwo,
+	  data: (uintptr) <nil>
+	 }),
+	 ExportedField: (map[interface {}]interface {}) (len=1) {
+	  (string) (len=3) "one": (bool) true
+	 }
+	}
+
+Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
+command as shown.
+	([]uint8) (len=32 cap=32) {
+	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
+	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
+	 00000020  31 32                                             |12|
+	}
+
+Custom Formatter
+
+Spew provides a custom formatter that implements the fmt.Formatter interface
+so that it integrates cleanly with standard fmt package printing functions. The
+formatter is useful for inline printing of smaller data types similar to the
+standard %v format specifier.
+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Custom Formatter Usage
+
+The simplest way to make use of the spew custom formatter is to call one of the
+convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
+functions have syntax you are most likely already familiar with:
+
+	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+	spew.Println(myVar, myVar2)
+	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
+	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
+
+See the Index for the full list convenience functions.
+
+Sample Formatter Output
+
+Double pointer to a uint8:
+	  %v: <**>5
+	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
+	 %#v: (**uint8)5
+	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
+
+Pointer to circular struct with a uint8 field and a pointer to itself:
+	  %v: <*>{1 <*><shown>}
+	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
+	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
+	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
+
+See the Printf example for details on the setup of variables being shown
+here.
+
+Errors
+
+Since it is possible for custom Stringer/error interfaces to panic, spew
+detects them and handles them internally by printing the panic information
+inline with the output.  Since spew is intended to provide deep pretty printing
+capabilities on structures, it intentionally does not return any errors.

+NewFormatter returns a custom formatter that satisfies the fmt.Formatter

+
+The custom formatter only responds to the %v (most compact), %+v (adds pointer
+addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
+combinations.  Any other verbs such as %x and %q will be sent to the the
+standard fmt package for formatting.  In addition, the custom formatter ignores
+the width and precision arguments (however they will still work on the format
+specifiers not handled by the custom formatter).
+
+Typically this function shouldn't be called directly.  It is much easier to make
+use of the custom formatter by calling one of the convenience functions such as
+Printf, Println, or Fprintf.

+
+## Install
+
+Requires Go 1.8 or above.
+
+Install with `go get github.com/denisenkom/go-mssqldb` .
+
+## Connection Parameters and DSN
+
+The recommended connection string uses a URL format:
+`sqlserver://username:password@host/instance?param1=value&param2=value`
+Other supported formats are listed below.
+
+### Common parameters:
+
+* `user id` - enter the SQL Server Authentication user id or the Windows Authentication user id in the DOMAIN\User format. On Windows, if user id is empty or missing Single-Sign-On is used.
+* `password`
+* `database`
+* `connection timeout` - in seconds (default is 0 for no timeout), set to 0 for no timeout. Recommended to set to 0 and use context to manage query and connection timeouts.
+* `dial timeout` - in seconds (default is 15), set to 0 for no timeout
+* `encrypt`
+  * `disable` - Data send between client and server is not encrypted.
+  * `false` - Data sent between client and server is not encrypted beyond the login packet. (Default)
+  * `true` - Data sent between client and server is encrypted.
+* `app name` - The application name (default is go-mssqldb)
+
+### Connection parameters for ODBC and ADO style connection strings:
+
+* `server` - host or host\instance (default localhost)
+* `port` - used only when there is no instance in server (default 1433)
+
+### Less common parameters:
+
+* `keepAlive` - in seconds; 0 to disable (default is 30)
+* `failoverpartner` - host or host\instance (default is no partner). 
+* `failoverport` - used only when there is no instance in failoverpartner (default 1433)
+* `packet size` - in bytes; 512 to 32767 (default is 4096)
+  * Encrypted connections have a maximum packet size of 16383 bytes
+  * Further information on usage: https://docs.microsoft.com/en-us/sql/database-engine/configure-windows/configure-the-network-packet-size-server-configuration-option
+* `log` - logging flags (default 0/no logging, 63 for full logging)
+  *  1 log errors
+  *  2 log messages
+  *  4 log rows affected
+  *  8 trace sql statements
+  * 16 log statement parameters
+  * 32 log transaction begin/end
+* `TrustServerCertificate`
+  * false - Server certificate is checked. Default is false if encypt is specified.
+  * true - Server certificate is not checked. Default is true if encrypt is not specified. If trust server certificate is true, driver accepts any certificate presented by the server and any host name in that certificate. In this mode, TLS is susceptible to man-in-the-middle attacks. This should be used only for testing.
+* `certificate` - The file that contains the public key certificate of the CA that signed the SQL Server certificate. The specified certificate overrides the go platform specific CA certificates.
+* `hostNameInCertificate` - Specifies the Common Name (CN) in the server certificate. Default value is the server host.
+* `ServerSPN` - The kerberos SPN (Service Principal Name) for the server. Default is MSSQLSvc/host:port.
+* `Workstation ID` - The workstation name (default is the host name)
+* `ApplicationIntent` - Can be given the value `ReadOnly` to initiate a read-only connection to an Availability Group listener.
+
+### The connection string can be specified in one of three formats:
+
+
+1. URL: with `sqlserver` scheme. username and password appears before the host. Any instance appears as
+    the first segment in the path. All other options are query parameters. Examples:
+
+  * `sqlserver://username:password@host/instance?param1=value&param2=value`
+  * `sqlserver://username:password@host:port?param1=value&param2=value`
+  * `sqlserver://sa@localhost/SQLExpress?database=master&connection+timeout=30` // `SQLExpress instance.
+  * `sqlserver://sa:mypass@localhost?database=master&connection+timeout=30`     // username=sa, password=mypass.
+  * `sqlserver://sa:mypass@localhost:1234?database=master&connection+timeout=30` // port 1234 on localhost.
+  * `sqlserver://sa:my%7Bpass@somehost?connection+timeout=30` // password is "my{pass"
+
+  A string of this format can be constructed using the `URL` type in the `net/url` package.
+
+```go
+  query := url.Values{}
+  query.Add("app name", "MyAppName")
+
+  u := &url.URL{
+      Scheme:   "sqlserver",
+      User:     url.UserPassword(username, password),
+      Host:     fmt.Sprintf("%s:%d", hostname, port),
+      // Path:  instance, // if connecting to an instance instead of a port
+      RawQuery: query.Encode(),
+  }
+  db, err := sql.Open("sqlserver", u.String())
+```
+
+2. ADO: `key=value` pairs separated by `;`. Values may not contain `;`, leading and trailing whitespace is ignored.
+     Examples:
+	
+  * `server=localhost\\SQLExpress;user id=sa;database=master;app name=MyAppName`
+  * `server=localhost;user id=sa;database=master;app name=MyAppName`
+
+3. ODBC: Prefix with `odbc`, `key=value` pairs separated by `;`. Allow `;` by wrapping
+    values in `{}`. Examples:
+	
+  * `odbc:server=localhost\\SQLExpress;user id=sa;database=master;app name=MyAppName`
+  * `odbc:server=localhost;user id=sa;database=master;app name=MyAppName`
+  * `odbc:server=localhost;user id=sa;password={foo;bar}` // Value marked with `{}`, password is "foo;bar"
+  * `odbc:server=localhost;user id=sa;password={foo{bar}` // Value marked with `{}`, password is "foo{bar"
+  * `odbc:server=localhost;user id=sa;password={foobar }` // Value marked with `{}`, password is "foobar "
+  * `odbc:server=localhost;user id=sa;password=foo{bar`   // Literal `{`, password is "foo{bar"
+  * `odbc:server=localhost;user id=sa;password=foo}bar`   // Literal `}`, password is "foo}bar"
+  * `odbc:server=localhost;user id=sa;password={foo{bar}` // Literal `{`, password is "foo{bar"
+  * `odbc:server=localhost;user id=sa;password={foo}}bar}` // Escaped `} with `}}`, password is "foo}bar"
+
+## Executing Stored Procedures
+
+To run a stored procedure, set the query text to the procedure name:
+```go
+var account = "abc"
+_, err := db.ExecContext(ctx, "sp_RunMe",
+	sql.Named("ID", 123),
+	sql.Named("Account", sql.Out{Dest: &account}),
+)
+```
+
+## Reading Output Parameters from a Stored Procedure with Resultset
+
+To read output parameters from a stored procedure with resultset, make sure you read all the rows before reading the output parameters:

+END
+`
+var bitout int64
+rows, err := db.QueryContext(ctx, "spwithoutputandrows", sql.Named("bitparam", sql.Out{Dest: &bitout}))
+var strrow string
+for rows.Next() {
+	err = rows.Scan(&strrow)
+}
+fmt.Printf("bitparam is %d", bitout)
+```
+
+## Caveat for local temporary tables
+
+Due to protocol limitations, temporary tables will only be allocated on the connection
+as a result of executing a query with zero parameters. The following query
+will, due to the use of a parameter, execute in its own session,
+and `#mytemp` will be de-allocated right away:
+
+```go
+conn, err := pool.Conn(ctx)
+defer conn.Close()
+_, err := conn.ExecContext(ctx, "select @p1 as x into #mytemp", 1)
+// at this point #mytemp is already dropped again as the session of the ExecContext is over
+```
+
+To work around this, always explicitly create the local temporary
+table in a query without any parameters. As a special case, the driver
+will then be able to execute the query directly on the
+connection-scoped session. The following example works:
+
+```go
+conn, err := pool.Conn(ctx)
+
+// Set us up so that temp table is always cleaned up, since conn.Close()
+// merely returns conn to pool, rather than actually closing the connection.
+defer func() {
+	_, _ = conn.ExecContext(ctx, "drop table #mytemp")  // always clean up
+	conn.Close() // merely returns conn to pool
+}()
+
+
+// Since we not pass any parameters below, the query will execute on the scope of
+// the connection and succeed in creating the table.
+_, err := conn.ExecContext(ctx, "create table #mytemp ( x int )")
+
+// #mytemp is now available even if you pass parameters
+_, err := conn.ExecContext(ctx, "insert into #mytemp (x) values (@p1)", 1)
+
+```
+
+## Return Status
+
+To get the procedure return status, pass into the parameters a
+`*mssql.ReturnStatus`. For example:
+```
+var rs mssql.ReturnStatus
+_, err := db.ExecContext(ctx, "theproc", &rs)
+log.Printf("status=%d", rs)
+```
+
+## Parameters
+
+The `sqlserver` driver uses normal MS SQL Server syntax and expects parameters in
+the sql query to be in the form of either `@Name` or `@p1` to `@pN` (ordinal position).
+
+```go
+db.QueryContext(ctx, `select * from t where ID = @ID and Name = @p2;`, sql.Named("ID", 6), "Bob")
+```
+
+### Parameter Types
+
+To pass specific types to the query parameters, say `varchar` or `date` types,
+you must convert the types to the type before passing in. The following types
+are supported:
+
+ * string -> nvarchar
+ * mssql.VarChar -> varchar
+ * time.Time -> datetimeoffset or datetime (TDS version dependent)
+ * mssql.DateTime1 -> datetime
+ * mssql.DateTimeOffset -> datetimeoffset
+ * "cloud.google.com/go/civil".Date -> date
+ * "cloud.google.com/go/civil".DateTime -> datetime2
+ * "cloud.google.com/go/civil".Time -> time
+ * mssql.TVP -> Table Value Parameter (TDS version dependent)
+
+## Important Notes
+
+ * [LastInsertId](https://golang.org/pkg/database/sql/#Result.LastInsertId) should
+    not be used with this driver (or SQL Server) due to how the TDS protocol
+	works. Please use the [OUTPUT Clause](https://docs.microsoft.com/en-us/sql/t-sql/queries/output-clause-transact-sql)
+	or add a `select ID = convert(bigint, SCOPE_IDENTITY());` to the end of your
+	query (ref [SCOPE_IDENTITY](https://docs.microsoft.com/en-us/sql/t-sql/functions/scope-identity-transact-sql)).
+	This will ensure you are getting the correct ID and will prevent a network round trip.
+ * [NewConnector](https://godoc.org/github.com/denisenkom/go-mssqldb#NewConnector)
+    may be used with [OpenDB](https://golang.org/pkg/database/sql/#OpenDB).
+ * [Connector.SessionInitSQL](https://godoc.org/github.com/denisenkom/go-mssqldb#Connector.SessionInitSQL)
+	may be set to set any driver specific session settings after the session
+	has been reset. If empty the session will still be reset but use the database
+	defaults in Go1.10+.
+
+## Features
+
+* Can be used with SQL Server 2005 or newer
+* Can be used with Microsoft Azure SQL Database
+* Can be used on all go supported platforms (e.g. Linux, Mac OS X and Windows)
+* Supports new date/time types: date, time, datetime2, datetimeoffset
+* Supports string parameters longer than 8000 characters
+* Supports encryption using SSL/TLS
+* Supports SQL Server and Windows Authentication
+* Supports Single-Sign-On on Windows
+* Supports connections to AlwaysOn Availability Group listeners, including re-direction to read-only replicas.
+* Supports query notifications
+
+## Tests
+
+`go test` is used for testing. A running instance of MSSQL server is required.
+Environment variables are used to pass login information.
+
+Example:
+
+    env SQLSERVER_DSN=sqlserver://user:pass@hostname/instance?database=test1 go test
+
+## Deprecated
+
+These features still exist in the driver, but they are are deprecated.
+
+### Query Parameter Token Replace (driver "mssql")
+
+If you use the driver name "mssql" (rather then "sqlserver") the SQL text
+will be loosly parsed and an attempt to extract identifiers using one of
+
+* ?
+* ?nnn
+* :nnn
+* $nnn
+
+will be used. This is not recommended with SQL Server. 
+There is at least one existing `won't fix` issue with the query parsing.
+
+Use the native "@Name" parameters instead with the "sqlserver" driver name.
+
+## Known Issues
+
+* SQL Server 2008 and 2008 R2 engine cannot handle login records when SSL encryption is not disabled.
+To fix SQL Server 2008 R2 issue, install SQL Server 2008 R2 Service Pack 2.
+To fix SQL Server 2008 issue, install Microsoft SQL Server 2008 Service Pack 3 and Cumulative update package 3 for SQL Server 2008 SP3.

+## Version 1.2 (2014-06-03)
+
+Changes:
+
+ - We switched back to a "rolling release". `go get` installs the current master branch again
+ - Version v1 of the driver will not be maintained anymore. Go 1.0 is no longer supported by this driver
+ - Exported errors to allow easy checking from application code
+ - Enabled TCP Keepalives on TCP connections
+ - Optimized INFILE handling (better buffer size calculation, lazy init, ...)
+ - The DSN parser also checks for a missing separating slash
+ - Faster binary date / datetime to string formatting
+ - Also exported the MySQLWarning type
+ - mysqlConn.Close returns the first error encountered instead of ignoring all errors
+ - writePacket() automatically writes the packet size to the header
+ - readPacket() uses an iterative approach instead of the recursive approach to merge splitted packets
+
+New Features:
+
+ - `RegisterDial` allows the usage of a custom dial function to establish the network connection
+ - Setting the connection collation is possible with the `collation` DSN parameter. This parameter should be preferred over the `charset` parameter
+ - Logging of critical errors is configurable with `SetLogger`
+ - Google CloudSQL support
+
+Bugfixes:
+
+ - Allow more than 32 parameters in prepared statements
+ - Various old_password fixes
+ - Fixed TestConcurrent test to pass Go's race detection
+ - Fixed appendLengthEncodedInteger for large numbers
+ - Renamed readLengthEnodedString to readLengthEncodedString and skipLengthEnodedString to skipLengthEncodedString (fixed typo)
+
+
+## Version 1.1 (2013-11-02)
+
+Changes:
+
+  - Go-MySQL-Driver now requires Go 1.1
+  - Connections now use the collation `utf8_general_ci` by default. Adding `&charset=UTF8` to the DSN should not be necessary anymore
+  - Made closing rows and connections error tolerant. This allows for example deferring rows.Close() without checking for errors
+  - `[]byte(nil)` is now treated as a NULL value. Before, it was treated like an empty string / `[]byte("")`
+  - DSN parameter values must now be url.QueryEscape'ed. This allows text values to contain special characters, such as '&'.
+  - Use the IO buffer also for writing. This results in zero allocations (by the driver) for most queries
+  - Optimized the buffer for reading
+  - stmt.Query now caches column metadata
+  - New Logo
+  - Changed the copyright header to include all contributors
+  - Improved the LOAD INFILE documentation
+  - The driver struct is now exported to make the driver directly accessible
+  - Refactored the driver tests
+  - Added more benchmarks and moved all to a separate file
+  - Other small refactoring
+
+New Features:
+
+  - Added *old_passwords* support: Required in some cases, but must be enabled by adding `allowOldPasswords=true` to the DSN since it is insecure
+  - Added a `clientFoundRows` parameter: Return the number of matching rows instead of the number of rows changed on UPDATEs
+  - Added TLS/SSL support: Use a TLS/SSL encrypted connection to the server. Custom TLS configs can be registered and used
+
+Bugfixes:
+
+  - Fixed MySQL 4.1 support: MySQL 4.1 sends packets with lengths which differ from the specification
+  - Convert to DB timezone when inserting `time.Time`
+  - Splitted packets (more than 16MB) are now merged correctly
+  - Fixed false positive `io.EOF` errors when the data was fully read
+  - Avoid panics on reuse of closed connections
+  - Fixed empty string producing false nil values
+  - Fixed sign byte for positive TIME fields
+

+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or

+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *

+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *

+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License

+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section

+---------------------------------------
+
+## Installation
+Simple install the package to your [$GOPATH](https://github.com/golang/go/wiki/GOPATH "GOPATH") with the [go tool](https://golang.org/cmd/go/ "go command") from shell:
+```bash
+$ go get -u github.com/go-sql-driver/mysql
+```
+Make sure [Git is installed](https://git-scm.com/downloads) on your machine and in your system's `PATH`.
+
+## Usage
+_Go MySQL Driver_ is an implementation of Go's `database/sql/driver` interface. You only need to import the driver and can use the full [`database/sql`](https://golang.org/pkg/database/sql/) API then.
+
+Use `mysql` as `driverName` and a valid [DSN](#dsn-data-source-name)  as `dataSourceName`:
+```go
+import "database/sql"
+import _ "github.com/go-sql-driver/mysql"
+
+db, err := sql.Open("mysql", "user:password@/dbname")
+```
+
+[Examples are available in our Wiki](https://github.com/go-sql-driver/mysql/wiki/Examples "Go-MySQL-Driver Examples").
+
+
+### DSN (Data Source Name)
+
+The Data Source Name has a common format, like e.g. [PEAR DB](http://pear.php.net/manual/en/package.database.db.intro-dsn.php) uses it, but without type-prefix (optional parts marked by squared brackets):
+```
+[username[:password]@][protocol[(address)]]/dbname[?param1=value1&...&paramN=valueN]
+```
+
+A DSN in its fullest form:
+```
+username:password@protocol(address)/dbname?param=value
+```
+
+Except for the databasename, all values are optional. So the minimal DSN is:
+```
+/dbname
+```
+
+If you do not want to preselect a database, leave `dbname` empty:
+```
+/
+```
+This has the same effect as an empty DSN string:
+```
+
+```
+
+Alternatively, [Config.FormatDSN](https://godoc.org/github.com/go-sql-driver/mysql#Config.FormatDSN) can be used to create a DSN string by filling a struct.
+
+#### Password
+Passwords can consist of any character. Escaping is **not** necessary.
+
+#### Protocol
+See [net.Dial](https://golang.org/pkg/net/#Dial) for more information which networks are available.
+In general you should use an Unix domain socket if available and TCP otherwise for best performance.
+
+#### Address
+For TCP and UDP networks, addresses have the form `host[:port]`.
+If `port` is omitted, the default port will be used.
+If `host` is a literal IPv6 address, it must be enclosed in square brackets.
+The functions [net.JoinHostPort](https://golang.org/pkg/net/#JoinHostPort) and [net.SplitHostPort](https://golang.org/pkg/net/#SplitHostPort) manipulate addresses in this form.
+
+For Unix domain sockets the address is the absolute path to the MySQL-Server-socket, e.g. `/var/run/mysqld/mysqld.sock` or `/tmp/mysql.sock`.
+
+#### Parameters
+*Parameters are case-sensitive!*
+
+Notice that any of `true`, `TRUE`, `True` or `1` is accepted to stand for a true boolean value. Not surprisingly, false can be specified as any of: `false`, `FALSE`, `False` or `0`.
+
+##### `allowAllFiles`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`allowAllFiles=true` disables the file Whitelist for `LOAD DATA LOCAL INFILE` and allows *all* files.
+[*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)
+
+##### `allowCleartextPasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`allowCleartextPasswords=true` allows using the [cleartext client side plugin](http://dev.mysql.com/doc/en/cleartext-authentication-plugin.html) if required by an account, such as one defined with the [PAM authentication plugin](http://dev.mysql.com/doc/en/pam-authentication-plugin.html). Sending passwords in clear text may be a security problem in some configurations. To avoid problems if there is any possibility that the password would be intercepted, clients should connect to MySQL Server using a method that protects the password. Possibilities include [TLS / SSL](#tls), IPsec, or a private network.
+
+##### `allowNativePasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        true
+```
+`allowNativePasswords=false` disallows the usage of MySQL native password method.
+
+##### `allowOldPasswords`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+`allowOldPasswords=true` allows the usage of the insecure old password method. This should be avoided, but is necessary in some cases. See also [the old_passwords wiki page](https://github.com/go-sql-driver/mysql/wiki/old_passwords).
+
+##### `charset`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        none
+```
+
+Sets the charset used for client-server interaction (`"SET NAMES <value>"`). If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`).
+
+Usage of the `charset` parameter is discouraged because it issues additional queries to the server.
+Unless you need the fallback behavior, please use `collation` instead.
+
+##### `collation`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        utf8_general_ci
+```
+
+Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail.
+
+A list of valid charsets for a server is retrievable with `SHOW COLLATION`.
+
+##### `clientFoundRows`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed.
+
+##### `columnsWithAlias`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example:
+
+```
+SELECT u.id FROM users as u
+```
+
+will return `u.id` instead of just `id` if `columnsWithAlias=true`.
+
+##### `interpolateParams`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`.
+
+*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are blacklisted as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!*
+
+##### `loc`
+
+```
+Type:           string
+Valid Values:   <escaped name>
+Default:        UTC
+```
+
+Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](https://golang.org/pkg/time/#LoadLocation) for details.
+
+Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter.
+
+Please keep in mind, that param values must be [url.QueryEscape](https://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`.
+
+##### `maxAllowedPacket`
+```
+Type:          decimal number
+Default:       4194304
+```
+
+Max packet size allowed in bytes. The default value is 4 MiB and should be adjusted to match the server settings. `maxAllowedPacket=0` can be used to automatically fetch the `max_allowed_packet` variable from server *on every connection*.
+
+##### `multiStatements`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded.
+
+When `multiStatements` is used, `?` parameters must only be used in the first statement.
+
+##### `parseTime`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string`
+The date or datetime like `0000-00-00 00:00:00` is converted into zero value of `time.Time`.
+
+
+##### `readTimeout`
+
+```
+Type:           duration
+Default:        0
+```
+
+I/O read timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+##### `rejectReadOnly`
+
+```
+Type:           bool
+Valid Values:   true, false
+Default:        false
+```
+
+
+`rejectReadOnly=true` causes the driver to reject read-only connections. This
+is for a possible race condition during an automatic failover, where the mysql
+client gets connected to a read-only replica after the failover.
+
+Note that this should be a fairly rare case, as an automatic failover normally
+happens when the primary is down, and the race condition shouldn't happen
+unless it comes back up online as soon as the failover is kicked off. On the
+other hand, when this happens, a MySQL application can get stuck on a
+read-only connection until restarted. It is however fairly easy to reproduce,
+for example, using a manual failover on AWS Aurora's MySQL-compatible cluster.
+
+If you are not relying on read-only transactions to reject writes that aren't
+supposed to happen, setting this on some MySQL providers (such as AWS Aurora)
+is safer for failovers.
+
+Note that ERROR 1290 can be returned for a `read-only` server and this option will
+cause a retry for that error. However the same error number is used for some
+other cases. You should ensure your application will never cause an ERROR 1290
+except for `read-only` mode when enabling this option.
+
+
+##### `serverPubKey`
+
+```
+Type:           string
+Valid Values:   <name>
+Default:        none
+```
+
+Server public keys can be registered with [`mysql.RegisterServerPubKey`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterServerPubKey), which can then be used by the assigned name in the DSN.
+Public keys are used to transmit encrypted data, e.g. for authentication.
+If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required.
+
+
+##### `timeout`
+
+```
+Type:           duration
+Default:        OS default
+```
+
+Timeout for establishing connections, aka dial timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+
+##### `tls`
+
+```
+Type:           bool / string
+Valid Values:   true, false, skip-verify, <name>
+Default:        false
+```
+
+`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side). Use a custom value registered with [`mysql.RegisterTLSConfig`](https://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig).
+
+
+##### `writeTimeout`
+
+```
+Type:           duration
+Default:        0
+```
+
+I/O write timeout. The value must be a decimal number with a unit suffix (*"ms"*, *"s"*, *"m"*, *"h"*), such as *"30s"*, *"0.5m"* or *"1m30s"*.
+
+
+##### System Variables
+
+Any other parameters are interpreted as system variables:
+  * `<boolean_var>=<value>`: `SET <boolean_var>=<value>`
+  * `<enum_var>=<value>`: `SET <enum_var>=<value>`
+  * `<string_var>=%27<value>%27`: `SET <string_var>='<value>'`
+
+Rules:
+* The values for string variables must be quoted with `'`.
+* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!
+ (which implies values of string variables must be wrapped with `%27`).
+
+Examples:
+  * `autocommit=1`: `SET autocommit=1`
+  * [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'`
+  * [`tx_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `SET tx_isolation='REPEATABLE-READ'`
+
+
+#### Examples
+```
+user@unix(/path/to/socket)/dbname
+```
+
+```
+root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local
+```
+
+```
+user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true
+```
+
+Treat warnings as errors by setting the system variable [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html):
+```
+user:password@/dbname?sql_mode=TRADITIONAL
+```
+
+TCP via IPv6:
+```
+user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci
+```
+
+TCP on a remote host, e.g. Amazon RDS:
+```
+id:password@tcp(your-amazonaws-uri.com:3306)/dbname
+```
+
+Google Cloud SQL on App Engine (First Generation MySQL Server):
+```
+user@cloudsql(project-id:instance-name)/dbname
+```
+
+Google Cloud SQL on App Engine (Second Generation MySQL Server):
+```
+user@cloudsql(project-id:regionname:instance-name)/dbname
+```
+
+TCP using default port (3306) on localhost:
+```
+user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped
+```
+
+Use the default protocol (tcp) and host (localhost:3306):
+```
+user:password@/dbname
+```
+
+No Database preselected:
+```
+user:password@/
+```
+
+
+### Connection pool and timeouts
+The connection pool is managed by Go's database/sql package. For details on how to configure the size of the pool and how long connections stay in the pool see `*DB.SetMaxOpenConns`, `*DB.SetMaxIdleConns`, and `*DB.SetConnMaxLifetime` in the [database/sql documentation](https://golang.org/pkg/database/sql/). The read, write, and dial timeouts for each individual connection are configured with the DSN parameters [`readTimeout`](#readtimeout), [`writeTimeout`](#writetimeout), and [`timeout`](#timeout), respectively.
+
+## `ColumnType` Support
+This driver supports the [`ColumnType` interface](https://golang.org/pkg/database/sql/#ColumnType) introduced in Go 1.8, with the exception of [`ColumnType.Length()`](https://golang.org/pkg/database/sql/#ColumnType.Length), which is currently not supported.
+
+## `context.Context` Support
+Go 1.8 added `database/sql` support for `context.Context`. This driver supports query timeouts and cancellation via contexts.
+See [context support in the database/sql package](https://golang.org/doc/go1.8#database_sql) for more details.
+
+
+### `LOAD DATA LOCAL INFILE` support
+For this feature you need direct access to the package. Therefore you must change the import path (no `_`):
+```go
+import "github.com/go-sql-driver/mysql"
+```
+
+Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)).
+
+To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::<name>` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore.
+
+See the [godoc of Go-MySQL-Driver](https://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details.
+
+
+### `time.Time` support
+The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your program.
+
+However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](https://golang.org/pkg/time/#Location) with the `loc` DSN parameter.
+
+**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes).
+
+Alternatively you can use the [`NullTime`](https://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`.
+
+
+### Unicode support
+Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default.
+
+Other collations / charsets can be set using the [`collation`](#collation) DSN parameter.
+
+Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default.
+
+See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support.
+
+## Testing / Development
+To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details.
+
+Go-MySQL-Driver is not feature-complete yet. Your help is very appreciated.
+If you want to contribute, you can work on an [open issue](https://github.com/go-sql-driver/mysql/issues?state=open) or review a [pull request](https://github.com/go-sql-driver/mysql/pulls).
