当我尝试在MS SQL 2005数据库上运行特定存储过程时,出现如下错误:
Subquery returned more than 1 value. This is not permitted when
the subquery follows =, !=, <, <= , >, >= or when the subquery
is used as an expression
查询中的SP非常长并且调用其他SP。这个错误显然是由SQL本身产生的,并且一直向上返回调用堆栈,但没有提到哪个SP或行号导致了问题。如何找出错误发生的位置,以便我可以更轻松地调试它?

使用Try/Catch block可以为您提供所需内容。
在CATCH块的范围内,可以使用以下系统函数来获取有关导致执行CATCH块的错误的信息:
* ERROR_NUMBER() returns the number of the error.
* ERROR_SEVERITY() returns the severity.
* ERROR_STATE() returns the error state number.
* ERROR_PROCEDURE() returns the name of the stored procedure or trigger where the error occurred.
* ERROR_LINE() returns the line number inside the routine that caused the error.
* ERROR_MESSAGE() returns the complete text of the error message. The text includes the values supplied for any substitutable parameters, such as lengths, object names, or times.
所以,在你的情况下,ERROR_LINE()和ERROR_PROCEDURE()应该是你想要的......
