操作步骤示例:

Create Procedure [dbo].[test]
@Name varchar(100),
@ID int Output   
As  
Begin   
SELECT @ID = UserID from tbl_UserMaster where  Name = @Name   
Return;
END     

如何调用这个过程

Declare @ID int    
EXECUTE [dbo].[test] 'Abhishek',@ID OUTPUT   
PRINT @ID

简单的方法是在Sql Server Management Studio (SSMS)中右键单击该过程，选择“Execute stored procedure…”，并根据提示为输入参数添加值。然后，SSMS将生成代码以在新的查询窗口中运行过程，并为您执行它。您可以研究生成的代码，了解它是如何完成的。

下面是存储过程

create procedure sp1
(
@id as int,
@name as nvarchar(20) out
)
as
begin
select @name=name from employee where id=@id
end

这是执行这个过程的方法

 declare @name1 nvarchar(10)
    exec sp1 1,@name1 out
    print @name1
