存储过程写法出错，请帮我看看急
谁能看看我这个存储过程哪里出错了？

CREATE PROCEDURE [dbo].[HasTask]
(
@UID int,
@RETURNVALUE int output
)
AS
declare @strUID varchar
set
@strUID = '"'+@UID+'"'
@RETURNVALUE = Select Count(*) from STaskTb as s inner join FTaskTb as f on s.FTID =

f.FTID where f.Executor like '%@UID%' and s.STID not in
(Select STID from TUpTb where UID =@UID)
GO



[解决办法]

SQL code

declare @strUID varchar (8000)
