Do you love XML? Have you been using XML with SQL Server? Many people have, starting way back when with SQL Server 7.0. Back then, there was no support for XML in the database, so we had to write external programs to convert the relational data into an XML format. This was time-consuming and often inefficient. When SQL Server 2000 came out, with its integrated support for XML, there were a lot of high expectations. Unfortunately, XML still couldn't be easily stored in the database, although it could be created and consumed.

They were left out of my first T-SQL article because of space limitations. However, I be... (more)

DDL Triggers

A number of years ago, I worked for a company that was developing internal applications with SQL Server 2000. We didn't have any real database administrators. I was given that responsibility, but I was really a developer, one of many in fact. The problem with this arrangement was that all the developers had high-level rights to SQL Server. Each one could make whatever changes seemed appr... (more)
