SQL Server 中使用 Try Catch 处理异常

 CREATE TABLE ErrorLog(
 errNum INT,
 ErrSev NVARCHAR(1000),
 ErrState INT,
 ErrProc NVARCHAR(1000),
 ErrLine INT,
 ErrMsg NVARCHAR(2000)
 )

 CREATE PROCEDURE ProcErrorLog
 AS
 BEGIN
      SELECT
         ERROR_NUMBER() AS ErrNum,--返回导致运行 CATCH 块的错误消息的错误号。
         ERROR_SEVERITY()AS ErrSev,--返回导致 CATCH 块运行的错误消息的严重级别
         ERROR_STATE() AS ErrState,--返回导致 CATCH 块运行的错误消息的状态号
         ERROR_PROCEDURE() AS ErrProc,--返回出现错误的存储过程名称
         ERROR_LINE()AS ErrLine,--返回发生错误的行号
         ERROR_MESSAGE()AS ErrMsg--返回导致 CATCH 块运行的错误消息的完整文本
      INSERT INTO ErrorLog VALUES(
         ERROR_NUMBER(),
         ERROR_SEVERITY(),
         ERROR_STATE(),
         ERROR_PROCEDURE(),
         ERROR_LINE(),
     ERROR_MESSAGE())
 END

 CREATE PROCEDURE TestErrorLog
 AS
 BEGIN
     BEGIN TRY
         SELECT GETDATE()
         SELECT 1/0--Evergreen divide by zero example!
     END TRY
     BEGIN CATCH
         SELECT 'There was an error! ' + ERROR_MESSAGE()
         ProcErrorLog --调用上面的存储过程,保存错误日志
         RETURN
     END CATCH;
 END
