如何将sql执行的错误消息记录到本地网站网站文件中实现过程
其实大家都知道sql数据库语句的错误信息都可以在sys.messages表里面找到,如：,假如如果在执行数据库语句在try...catch中 咱们可以通过以下具体相关方法获取错误信息。sql数据库语句如下：,复制具体相关代码 具体相关代码如下:,BEGIN TRY SELECT 3 / 0 END TRY BEGIN CATCh DECLARE @errornumber INT DECLARE @errorseverity INT DECLA,现在咱们来定义一个存储过程，其目的就是往本地网站网站文件中写入信息。,sql脚本如下：,复制具体相关代码 具体相关代码如下:,CREATE Proc [dbo].[UCreateOrAppendTextFile](@Filename VarChar(100),@Text nVarchar(4000)) AS DECLARE
复制具体相关代码 具体相关代码如下:
