我试图执行此代码，但没有存储过程，它正常工作，并且出错了。
错误是： 消息102，级别15，状态1，过程UV_MTBF，第251行 'Event_'附近的语法不正确。
存储过程的长度是否有限制？ 有人可以帮我处理我的代码吗？
*****编辑****** 我的问题是'+ QUOTENAME（@ category，N''''）+ N' 我想从存储过程中收到的变量中添加一个整数。我该怎么办？
在此处输入代码
CREATE PROCEDURE dbo.MTBFCalculation @Category int, @Action bit, @relateToParent bit

答案 0 :(得分：0)
这部分查询
where EventCategory_ID=' + QUOTENAME(@category,N'''') + N')
2个选项，您将@category的值转换为字符串，然后与动态查询连接
where EventCategory_ID=' + convert(varchar(10), @category)
或者，您将值作为参数传递。
为此选项，您在动态查询中指定@category
where EventCategory_ID= @category
and (ParallelStatus=3 ....
并将值传递到sp_executesql
EXEC sp_executesql @Event, N'@category int', @category
顺便说一句，使用动态查询时，首选方法2
