2.获得错误信息的函数表:

下面系统函数在CATCH块有效.可以用来得到更多的错误信息:

函数	描述
ERROR_NUMBER()	返回导致运行 CATCH 块的错误消息的错误号。
ERROR_SEVERITY()	返回导致 CATCH 块运行的错误消息的严重级别
ERROR_STATE()	返回导致 CATCH 块运行的错误消息的状态号
ERROR_PROCEDURE()	返回出现错误的存储过程名称
ERROR_LINE()	返回发生错误的行号
ERROR_MESSAGE()	返回导致 CATCH 块运行的错误消息的完整文本

BEGIN TRY

Try Statement 1

Try Statement 2

...

Try Statement M

END TRY

BEGIN CATCH

Catch Statement 1

Catch Statement 2

...

Catch Statement N

END CATCH
