+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          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

+   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

+      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.

-## Statement Parameters
+## 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:
+```go
+sqltextcreate := `
+CREATE PROCEDURE spwithoutputandrows
+	@bitparam BIT OUTPUT
+AS BEGIN
+	SET @bitparam = 1
+	SELECT 'Row 1'
+END

+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).
@@ -126,6 +196,37 @@ the sql query to be in the form of either `@Name` or `@p1` to `@pN` (ordinal pos

+### 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+.
