Andy Warren

I started my SQL journey here at SQLServerCentral as one of the founders, helping to build a place to share and learn that continues to thrive under the editorial guidance of my friend Steve Jones. I've done a lot of volunteer work over the years ranging from our local SQL group (oPASS, SQLOrlando) to serving on the Board of Directors of PASS to designing and building the framework of SQLSaturday (which has gone on to produce more than 1000 locally managed events since we started in 2007). These days I manage a DBA team, but over the years I've been a trainer, consultant, contractor, and DBA. I'm rarely present on social media, the best way to contact me is here, LinkedIn, or via email.

Worst Practices - Not Using Primary Keys and Clustered Indexes

Two weeks ago Andy started his wildly successful series on Worst Practices. This week he continues that series discussing why failing to use primary keys and clustered indexes are worst practices. Agree or disagree, read the article and join the discussion. One thing you'll have to admit, reading an article by Andy is a lot more interesting than reading Books Online!
