我想有人会说在每条语句执行之后都通过@@ERROR判断是否有Exception出现,我知道很多人喜欢这么做,而事实上,我现在真在维护的一些Stored procedure就是这么做的:全篇都是IF@@ERROR RETURN。其实我们完全可以通过其它的方式是我们的SQL看出来更加优雅一点。那就是使用我们很熟悉的TRY CATCH。在SQL Server中我们通过BEGIN T...
但是上面的处理有一种不太理想的做法是:在每个Stored procedure中为不同的Error定义了Message。其实在很多情况下,每个Stored procedure都需要处理一些共同的Error,而且对于.NET Application来说往往是通过Message来判断Exception的类型,所以保持各个Stored Procedure的Message的一致性和Stored procedure和Application的Message的一致...

You create a stored procedure that uses a table-valued parameter (TVP) in Microsoft SQL Server 2012. You use SQL Profiler or SQL Server Extended Events to capture the RPC:Starting and RPC:Completed events. You run a query...
