使用这个查询，你可以执行任何存储过程(带或不带输出参数):

DECLARE @temp varchar(100)  
EXEC my_sp
    @parameter1 = 1, 
    @parameter2 = 2, 
    @parameter3 = @temp output, 
    @parameter4 = 3, 
    @parameter5 = 4
PRINT @temp

这里@temp的数据类型应该与存储过程中的@parameter3相同。

CREATE PROCEDURE Myproc @parm varchar(10), **@parm1OUT varchar(30) OUTPUT**, **@parm2OUT varchar(30) OUTPUT** AS SELECT @parm1OUT='parm 1' + @parm SELECT @parm2OUT='parm 2' + @parm GO DECLARE @SQLString NVARCHAR(500) DECLARE @ParmDefinition NVARCHAR(500) DECLARE @parmIN VARCHAR(10) DECLARE @parmRET1 VARCHAR(30) DECLARE @parmRET2 VARCHAR(30) SET @parmIN=' returned' SET @SQLString=N'EXEC Myproc @parm, @parm1OUT OUTPUT, @parm2OUT OUTPUT' SET @ParmDefinition=N'@parm varchar(10), @parm1OUT varchar(30) OUTPUT, @parm2OUT varchar(30) OUTPUT' EXECUTE sp_executesql @SQLString, @ParmDefinition, @parm=@parmIN, @parm1OUT=@parmRET1 OUTPUT,@parm2OUT=@parmRET2 OUTPUT SELECT @parmRET1 AS "parameter 1", @parmRET2 AS "parameter 2" GO DROP PROCEDURE Myproc

试试这个;对于多个输出参数，它工作得很好:

CREATE PROCEDURE [endicia].[credentialLookup]
@accountNumber varchar(20),
@login varchar(20) output,
@password varchar(50) output
AS
BEGIN
SET NOCOUNT ON;
SELECT top 1 @login = [carrierLogin],@password = [carrierPassword]
  FROM [carrier_account] where carrierLogin = @accountNumber
  order by clientId, id
END

Try for the result: 
SELECT *FROM [carrier_account] 
DECLARE @login varchar(20),@password varchar(50)
exec [endicia].[credentialLookup] '588251',@login OUTPUT,@password OUTPUT
SELECT 'login'=@login,'password'=@password

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stored_proc的定义:

create proc product(@a int,@b int)
as
return @a * @b

这是从Python中执行的: Conn = pyodbc.connect('…') Cursor = conn.cursor()

sql = """
SET NOCOUNT ON
declare @r float
exec @r=dbo.product 5,4
select @r
"""
result = cursor.execute(sql)
print (result.fetchall())
