This is a two part series on how triggers work in the two latest versions of MS SQL Server. Because there are some pretty significant additions in trigger functionality from 7.0 to 2000, we'll first need to look at what the two versions have in common. The second part to this series will look at the differences between the two MS SQL Server versions.

This article will cover using one of the many capabilities of CTE’s, implementing recursive functions. A recursive function is a one that iteratively executes itself.

When it comes to auditing index use in SQL Server databases, I sometimes get overwhelmed. For example, how to do you go about auditing indexes in a database with over 1,500 tables? While auditing a single index is relatively straight-forward, auditing thousands of them in multiple databases is not an easy task. Whether the task is easy or not, it is an important task if you want to optimize the performance of your SQL Server databases.

Referential Ingegrity is a critical part of any well designed RDBMS application, not just a part of Oracle, DB2, or some other platform. SQL Server has tools to make it easy, but a developer has to take the time to ensure that it is setup correctly, and ignorance is no excuse. New author Nick Duckstein brings us a look at basic RI and how you can set this up in your database.
