我得到错误为什么？存储过程语法结构
ALTER PROCEDURE dbo.verifGuids
@value char(36),
@message char(1)Output
AS
Begin
select value FROM guids WHERE @value=value;
If @value=value
BEGIN
DELETE value FROM guids WHERE @value=value ;
SET @message = 0
END
Else
BEGIN
Set @message = 1
END
Return @message
END
感谢
请你尝试下面的方法：
ALTER PROCEDURE dbo.verifGuids
@value char(36),
@message char(1)Output
AS
Begin
DECLARE @SelectValue char(36)
select @SelectValue = value FROM guids WHERE @value=value;
If @[email protected]
BEGIN
DELETE value FROM guids WHERE @value=value ;
SET @message = 0
END
Else
BEGIN
Set @message = 1
END
Return @message
END
你没有指定要查询到一个变量进行比较的数据库值。另外，您在删除时指定了列。尝试是这样的：
DELETE FROM guids WHERE [email protected];
IF @@ROWCOUNT > 0
BEGIN
SET @message = 0
END
ELSE
BEGIN
SET @message = 1
END
你得到什么实际的错误？ – 2012-01-08 02:06:21
列值在VS中无效... – FrankSharp 2012-01-08 02:11:33
这一行是毫无意义的，并且不分配任何东西：select value FROM GUID WHERE @ value = value – 2012-01-08 02:14:50
