I started off doing software development with Coldfusion and VB6/VB.NET in my first few jobs. Fortunately, the database was always SQL Server. Over time, I just gravitated towards working on the database partly because the job demanded it and partly because I seemed to enjoy working with the database more than the front end. I have had forays into MySQL, and even been offered full-time jobs on MySQL which I turned down. After having worked with both and comparing the two and seeing how much better SQL Server is, I find MySQL development frustrating because SQL Server makes so many things so much easier, and is far far more capable. I also really like the SQL Server community.
