Introduction to Table-Valued Parameters with Example

Wed, 03 Sep 2008 21:19:55 GMT

Table-Valued Parameters is a new feature introduced in SQL SERVER 2008. In earlier versions of SQL SERVER it is not possible to pass a table variable in stored procedure as a parameter, but now in SQL SERVER 2008 we can use Table-Valued Parameter to send multiple rows of data to a stored procedure or a function without creating a temporary table or passing so many parameters. This is one feature all the SQL Server developer were waiting for long time. This article explains how it can be used with very simple words.

Introduction to Filtered Index - Improve performance

Wed, 03 Sep 2008 21:18:36 GMT

Filtered Index is a new feature in SQL SERVER 2008. Filtered Index is used to index a portion of rows in a table that means it applies filter on INDEX which improves query performance, reduce index maintenance costs, and reduce index storage costs compared with full-table indexes. When we see an Index created with some WHERE clause then that is actually a FILTERED INDEX. I am sure this feature will change how the indexes are created in SQL Server.

Scheduling Jobs in SQL Server Express with Service Broker

Tue, 02 Sep 2008 11:38:15 GMT

"As we all know SQL Server 2005 Express is a very powerful free edition of SQL Server 2005. However it does not contain SQL Server Agent service. Because of this scheduling jobs is not possible. So if we want to do this we have to install a free or commercial 3rd party product. This usually isn't allowed due to the security policies of many hosting companies and thus presents a problem. Maybe we want to schedule daily backups, database reindexing, statistics updating, etc. This is why I wanted to have a solution based only on SQL Server 2005 Express and not dependent on the hosting company. And of course there is one based on our old friend the Service Broker."

Immediate deadlock notifications without changing existing code

Fri, 18 Jul 2008 09:00:36 GMT

In my previous post about immediate deadlock notifications in SQL Server 2005 I've shown a way to use a try catch block to get the deadlock error. The con of this method, although it uses best practice for error handling in SQL Server 2005, is that you have to change existing code and it doesn't work for non stored procedure code. And that IS a pretty BIG con! So here's a solution to this con.
