PART II中，我给出了一个完整的例子说明了：如何在将message定义在sys.messages中保证message的一致性和可维护性；如何在Stored procedure中使用RAISERROR将一个可预知的Error抛出；如何在Stored procedure中使用TRY/CATCH进行异常的捕捉；在Application如果处理从SQL Server抛出的Exception。实际上，SQL Server database Engine抛出、被我们的.NET最终捕获的SqlException，我们通过SqlException的属性可以得到Error的相关信息。下面是SqlException的属性列表：  阅读全文]]>http://www.cnblogs.com/artech/archive/2007/12/17/997209.htmlArtechArtechMon, 17 Dec 2007 04:41:00 GMThttp://www.cnblogs.com/artech/archive/2007/12/17/997209.htmlhttp://www.cnblogs.com/artech/comments/997209.htmlhttp://www.cnblogs.com/artech/archive/2007/12/17/997209.html#Feedback6http://www.cnblogs.com/artech/comments/commentRss/997209.htmlhttp://www.cnblogs.com/artech/services/trackbacks/997209.html上面一节中，我通过RAISERROR重写了创建User的Stored procedure，实际上上面的Stored procedure是有问题的。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语句仍然会被执行的。我想很多人会说在RAISERROR后加一个Return就可以了嘛。不错这是一个常用的解决方案，但是我不倾向于使用这种方法。为了更清楚地说明这个问题，我们举另一个相关的例子，上面我们介绍了创建User的例子，我们现在来引入另一个例子：如何将一个User添加到一个Role里面  阅读全文]]>http://www.cnblogs.com/artech/archive/2007/12/17/997182.htmlArtechArtechMon, 17 Dec 2007 00:38:00 GMThttp://www.cnblogs.com/artech/archive/2007/12/17/997182.htmlhttp://www.cnblogs.com/artech/comments/997182.htmlhttp://www.cnblogs.com/artech/archive/2007/12/17/997182.html#Feedback7http://www.cnblogs.com/artech/comments/commentRss/997182.htmlhttp://www.cnblogs.com/artech/services/trackbacks/997182.html阅读全文]]>http://www.cnblogs.com/artech/archive/2007/08/24/868956.htmlArtechArtechFri, 24 Aug 2007 15:16:00 GMThttp://www.cnblogs.com/artech/archive/2007/08/24/868956.htmlhttp://www.cnblogs.com/artech/comments/868956.htmlhttp://www.cnblogs.com/artech/archive/2007/08/24/868956.html#Feedback17http://www.cnblogs.com/artech/comments/commentRss/868956.htmlhttp://www.cnblogs.com/artech/services/trackbacks/868956.html第一部分中，我们讨论了APPLY和CTE这两个T-SQL Enhancement。APPLY实现了Table和TVF的Join，CTE通过创建“临时的View”的方式使问题化繁为简。现在我们接着来讨论另外两个重要的T-SQL Enhancement Items：PIVOT和Ranking。  阅读全文]]>http://www.cnblogs.com/artech/archive/2007/08/23/867412.htmlArtechArtechThu, 23 Aug 2007 13:46:00 GMThttp://www.cnblogs.com/artech/archive/2007/08/23/867412.htmlhttp://www.cnblogs.com/artech/comments/867412.htmlhttp://www.cnblogs.com/artech/archive/2007/08/23/867412.html#Feedback20http://www.cnblogs.com/artech/comments/commentRss/867412.htmlhttp://www.cnblogs.com/artech/services/trackbacks/867412.html阅读全文]]>http://www.cnblogs.com/artech/archive/2007/04/03/698755.htmlArtechArtechTue, 03 Apr 2007 10:55:00 GMThttp://www.cnblogs.com/artech/archive/2007/04/03/698755.htmlhttp://www.cnblogs.com/artech/comments/698755.htmlhttp://www.cnblogs.com/artech/archive/2007/04/03/698755.html#Feedback4http://www.cnblogs.com/artech/comments/commentRss/698755.htmlhttp://www.cnblogs.com/artech/services/trackbacks/698755.html阅读全文]]>http://www.cnblogs.com/artech/archive/2007/04/03/698762.htmlArtechArtechTue, 03 Apr 2007 10:54:00 GMThttp://www.cnblogs.com/artech/archive/2007/04/03/698762.htmlhttp://www.cnblogs.com/artech/comments/698762.htmlhttp://www.cnblogs.com/artech/archive/2007/04/03/698762.html#Feedback8http://www.cnblogs.com/artech/comments/commentRss/698762.htmlhttp://www.cnblogs.com/artech/services/trackbacks/698762.html阅读全文]]>http://www.cnblogs.com/artech/archive/2007/03/26/689100.htmlArtechArtechMon, 26 Mar 2007 13:51:00 GMThttp://www.cnblogs.com/artech/archive/2007/03/26/689100.htmlhttp://www.cnblogs.com/artech/comments/689100.htmlhttp://www.cnblogs.com/artech/archive/2007/03/26/689100.html#Feedback9http://www.cnblogs.com/artech/comments/commentRss/689100.htmlhttp://www.cnblogs.com/artech/services/trackbacks/689100.html阅读全文]]>http://www.cnblogs.com/artech/archive/2007/03/26/687769.htmlArtechArtechSun, 25 Mar 2007 18:59:00 GMThttp://www.cnblogs.com/artech/archive/2007/03/26/687769.htmlhttp://www.cnblogs.com/artech/comments/687769.htmlhttp://www.cnblogs.com/artech/archive/2007/03/26/687769.html#Feedback29http://www.cnblogs.com/artech/comments/commentRss/687769.htmlhttp://www.cnblogs.com/artech/services/trackbacks/687769.html阅读全文]]>
