关于SQLServer2005的学习笔记—异常捕获及处理

DECLARE @ErrNum INT,@RowCount INT;

--能够捕获的0做除数错误

SELECT 1/0;

SET @ErrNum=@@error;

SET @RowCount=@@rowcount;

PRINT 'Encount ERROR';

PRINT @ErrNum

PRINT @RowCount

--不能被捕获的数据转换错误

SELECT 'A'+1

SET @ErrNum=@@error;

SET @RowCount=@@rowcount;

PRINT 'Encount Serious ERROR';

PRINT @ErrNum

PRINT @RowCount

        ErrorMessage  VARCHAR(1000),

        ErrorSeverity INT,

        ErrorState    INT,

        ErrorLine     INT,

        ErrorProcedure VARCHAR(128)

--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
