这也是我在上面的Sample中通过SET @error = @@ERROR将@@ERROR进行预存的原因。 @@ERROR实际上代表的是在编写SQL或者Stored procedure中对异常的识别,大多数我们通过@@ERROR来判断一段SQL语句是否成功执行,保证没有遇到不可预知的异常。对于一些可以预知的异常在SQL中又该如何处理呢? 我发现很多程序员喜欢使用Output...
我之所以没有立即指出,是因为这是一个很容易犯的错误,尤其是习惯了.NET Exception Handling的人更容易犯这样的错误。我们知道在.NET Application中,如果出现一个未处理的Exception,程序将立即终止,后续的程序将不会执行,但是对于上面的SQL则不一样,虽然我们通过RAISERROR将Error抛出,但是SQL的指定并不会被终止,INSERT...

篇文章中,我将会介绍我对于基于Database编程中Exception Handling的一些粗浅的认识:在编写Stored Procedure时,如何抛出一个可预知的Exception,ADO.NET如何处理从Database抛出的Exception,如何保存基于Database Exception的Error Message,如何在Database和.NET Application之间进行消息的传递[注:这里的Database主要指SQL Server]...
