This topic describes how to create a Transact-SQL stored procedure by using SQL Server Management Studio and by using the Transact-SQL CREATE PROCEDURE statement.

• Before you begin: Permissions

• To create a procedure, using:  SQL Server Management Studio, Transact-SQL

Permissions

Requires CREATE PROCEDURE permission in the database and ALTER permission on the schema in which the procedure is being created.

How to Create a Stored Procedure

You can use one of the following:

• SQL Server Management Studio

• Transact-SQL

Using SQL Server Management Studio

To create a procedure in Object Explorer

1. In Object Explorer, connect to an instance of Database Engine and then expand that instance.

2. Expand Databases, expand the AdventureWorks2012 database, and then expand Programmability.

3. Right-click Stored Procedures, and then click New Stored Procedure.

4. On the Query menu, click Specify Values for Template Parameters.

5. In the Specify Values for Template Parameters dialog box, enter the following values for the parameters shown.

   Parameter	Value
   Author	Your name
   Create Date	Today's date
   Description	Returns employee data.
   Procedure_name	HumanResources.uspGetEmployeesTest
   @Param1	@LastName
   @Datatype_For_Param1	nvarchar(50)
   Default_Value_For_Param1	NULL
   @Param2	@FirstName
   @Datatype_For_Param2	nvarchar(50)
   Default_Value_For_Param2	NULL

6. Click OK.

7. In the Query Editor, replace the SELECT statement with the following statement:

   SELECT FirstName, LastName, Department
   FROM HumanResources.vEmployeeDepartmentHistory
   WHERE FirstName = @FirstName AND LastName = @LastName
       AND EndDate IS NULL;
   

8. To test the syntax, on the Query menu, click Parse. If an error message is returned, compare the statements with the information above and correct as needed.

9. To create the procedure, from the Query menu, click Execute. The procedure is created as an object in the database.

10. To see the procedure listed in Object Explorer, right-click Stored Procedures and select Refresh.

11. To run the procedure, in Object Explorer, right-click the stored procedure name HumanResources.uspGetEmployeesTest and select Execute Stored Procedure.

Using Transact-SQL

To create a procedure in Query Editor

1. In Object Explorer, connect to an instance of Database Engine.

2. From the File menu, click New Query.

3. Copy and paste the following example into the query window and click Execute. This example creates the same stored procedure as above using a different procedure name.

   USE AdventureWorks2012;
   GO
   CREATE PROCEDURE HumanResources.uspGetEmployeesTest2 
       @LastName nvarchar(50), 
       @FirstName nvarchar(50) 
   AS 
   
       SET NOCOUNT ON;
       SELECT FirstName, LastName, Department
       FROM HumanResources.vEmployeeDepartmentHistory
       WHERE FirstName = @FirstName AND LastName = @LastName
       AND EndDate IS NULL;
   GO
   

4. To run the procedure, copy and paste the following example into a new query window and click Execute. Notice that different methods of specifying the parameter values are shown.

   EXECUTE HumanResources.uspGetEmployeesTest2 N'Ackerman', N'Pilar';
   -- Or
   EXEC HumanResources.uspGetEmployeesTest2 @LastName = N'Ackerman', @FirstName = N'Pilar';
   GO
   -- Or
   EXECUTE HumanResources.uspGetEmployeesTest2 @FirstName = N'Pilar', @LastName = N'Ackerman';
   GO
