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())

CREATE PROCEDURE DBO.MY_STORED_PROCEDURE
(@PARAM1VALUE INT,
@PARAM2VALUE INT,
@OUTPARAM VARCHAR(20) OUT)
AS 
BEGIN
SELECT * FROM DBO.PARAMTABLENAME WHERE PARAM1VALUE=@PARAM1VALUE
END

DECLARE @OUTPARAM2 VARCHAR(20)
EXEC DBO.MY_STORED_PROCEDURE 1,@OUTPARAM2 OUT
PRINT @OUTPARAM2

这个怎么样?它非常简单:

下面的SPROC有一个输出参数@ParentProductID 我们希望将@ParentProductID的输出值选择为下面声明的@MyParentProductID。 代码如下: 声明@MyParentProductID int exec p_CheckSplitProduct @ProductId = 4077， @ParentProductID = @MyParentProductID输出 选择@MyParentProductID

你可以这样做:

declare @rowCount int
exec yourStoredProcedureName @outputparameterspOf = @rowCount output

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

首先，声明输出变量:

DECLARE @MyOutputParameter INT;

然后，执行存储过程，你可以不带参数名，就像这样:

EXEC my_stored_procedure 'param1Value', @MyOutputParameter OUTPUT

或者使用参数名:

EXEC my_stored_procedure @param1 = 'param1Value', @myoutput = @MyOutputParameter OUTPUT

最后，你可以通过执行SELECT命令查看输出结果:

SELECT @MyOutputParameter
