请考虑以下T-sql代码段：
CREATE PROC dbo.SquareNum(@i INT OUTPUT)
AS
BEGIN
SET @i = @i * @i
--SELECT @i
END
GO
DECLARE @a INT = 3,@b INT = 5
EXEC dbo.SquareNum @a OUTPUT
EXEC dbo.SquareNum @b
SELECT @a AS ASQUARE,@b AS BSQUARE
GO
DROP PROC dbo.SquareNum
结果集是：
ASQUARE BSQUARE ----------- ----------- 9 5
可以看出,@ b不是平方,b / c它没有作为输出参数传入(传入参数时没有OUTPUT限定符).
我想知道是否有一种方法可以检查存储过程体(在本例中为dbo.SquareNum体),以查看参数是否确实已作为OUTPUT参数传入？
解决方法
------ THIS WILL GIVE YOU THE BOTH VALUE IN squared------
CREATE PROC dbo.SquareNum(@i INT OUTPUT)
AS
BEGIN
SET @i = @i * @i
--SELECT @i
END
GO
DECLARE @a INT = 3,@b INT = 5
EXEC dbo.SquareNum @a OUTPUT
EXEC dbo.SquareNum @b OUTPUT
SELECT @a AS ASQUARE,@b AS BSQUARE
GO
DROP PROC dbo.SquareNum
-----TO CHECK STORED PROCEDURE BODY-----
SELECT OBJECT_NAME(object_id),OBJECT_DEFINITION(object_id)
FROM sys.procedures
WHERE OBJECT_DEFINITION(object_id) =(SP_NAME)
