Performance tuning is an ongoing battle in SQL Server, but having a little knowledge up front when designing an application can greatly reduce the efforts. Do you know which performs better: stored procedures or triggers? There aren't many places where the two are interchangeable, but knowing the impacts of each might change the way you build an application. Read about this analysis by Vijaya Kumar.   Read more...

This is the second of a two part series on how triggers work in the two latest versions of MS SQL Server. The first part dealt with what is common between the two versions. This article will detail what's been added to SQL Server 2000.   Read more...

This is a two part series on how triggers work in the two latest versions of MS SQL Server.
