SQLserver 存储过程执行错误记录到表

对于在执行存储过程中碰到的一些错误，如果未及时捕获或者说传递给前端应用程序来，在这样的情形下，故障的排查显得尤为困难。基于此，我们可以可以将这些错误信息记录到日志，同时也可以将其传递给前端应用程序。如本文的示例。

一、将错误信息记录到表

CREATE TABLE ErrorLog
(
ID             INT IDENTITY (1,1) NOT NULL,
ErrorNumber    INT,
ErrorMessage   VARCHAR(1000),
ErrorSeverity  INT,
ErrorState     INT,
ErrorLine      INT,
ErrorProcedure VARCHAR(128),
ErrorDate      datetime
);

CREATE PROCEDURE CatchErrorDemo
AS --相关业务逻辑

BEGIN TRY
SELECT  1 / 0;
END TRY
--相关错误捕获
BEGIN CATCH
PRINT 'Error Number:' + CAST(ERROR_NUMBER() AS VARCHAR(10));
PRINT 'Error Serverity: ' + CAST(ERROR_SEVERITY() AS VARCHAR(10));
PRINT 'Error State: ' + CAST(ERROR_STATE() AS VARCHAR(10));
PRINT 'Error Procedure: ' + ERROR_PROCEDURE();
PRINT 'Error Line: ' + CAST(ERROR_LINE() AS VARCHAR(10));
PRINT 'Error Message: ' + ERROR_MESSAGE();
INSERT  INTO ErrorLog
( ErrorNumber ,
ErrorSeverity ,
ErrorState ,
ErrorProcedure ,
ErrorLine ,
ErrorMessage ,
ErrorDate
)
VALUES  ( ERROR_NUMBER() ,
ERROR_SEVERITY() ,
ERROR_STATE() ,
ERROR_PROCEDURE() ,
ERROR_LINE() ,
ERROR_MESSAGE() ,
GETDATE()
)

END CATCH;

--执行相关存储过程，并查询日志表，同时与系统消息表进行对比
EXEC CatchErrorDemo;
SELECT * FROM ErrorLog;

二、传递错误信息

CREATE PROC CatchErrorDemo2
@a INT ,
@rtn VARCHAR(20) OUTPUT ,
@rtn_message VARCHAR(200) OUTPUT
AS
BEGIN
BEGIN TRY
DECLARE @result INT;

SET @result = 'A' + @a;
END TRY
BEGIN CATCH
SET @rtn = @@ERROR;

SET @rtn_message = 'Error Number: '
+ CAST(ERROR_NUMBER() AS VARCHAR(10)) + ' Error Serverity: '
+ CAST(ERROR_SEVERITY() AS VARCHAR(10)) + ' Error State: '
+ CAST(ERROR_STATE() AS VARCHAR(10)) + ' Error Procedure: '
+ ERROR_PROCEDURE() + ' Error Line: '
+ CAST(ERROR_LINE() AS VARCHAR(10)) + ' Error Message: '
+ ERROR_MESSAGE();
END CATCH;
END;
GO

--调用存储过程
DECLARE @rtn INT ,
@rtn_message VARCHAR(200);
EXEC CatchErrorDemo2 0, @rtn OUTPUT, @rtn_message OUTPUT;
PRINT @rtn;
PRINT @rtn_message;

245
Error Number: 245 Error Serverity: 16 Error State: 1 Error Procedure: CatchErrorDemo2 Error Line: 10
Error Message: 在将 varchar 值 'A' 转换成数据类型 int 时失败。
