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
