我有以下存储过程:
ALTER PROCEDURE [dbo].[CheckAdminExists]
@SID NVARCHAR(50),
@AdminName NVARCHAR(MAX)
AS
SELECT
Administrator.ID
FROM
Administrator
WHERE
Administrator.SID = @SID
AND Administrator.Name = @AdminName
GO
现在,我想用这样的代码创建另一个SP:
IF NOT NULL (EXECUTE CheckAdminExists 'S-1','Admin')
--do something
ELSE
--do something else
正确的语法是什么?
最佳答案
您不应为此使用存储过程,而应使用函数来检查管理员是否存在。
然后在新的存储过程中,调用CheckAdminExists函数:
CREATE FUNCTION [dbo].[CheckAdminExists] (@SID NVARCHAR(50), @AdminName NVARCHAR(MAX))
RETURNS BIT
AS
BEGIN
DECLARE @RetVal INT
SELECT @RetVal = COUNT(Administrator.ID)
FROM
Administrator
WHERE
Administrator.SID = @SID
AND Administrator.Name = @AdminName
IF @RetVal > 0
BEGIN
RETURN 1
END
RETURN 0
END
Then in your stored procedure call the function:
DECLARE @AdminExists BIT
SELECT @AdminExists = [dbo].[CheckAdminExists]
IF @AdminExists
BEGIN
-- your code
END
ELSE
BEGIN
-- your code
END
关于sql - IF/ELSE取决于存储过程的结果,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/10248217/
