This editorial was originally published on May 18, 2019. It is being re-run as Steve is on holiday. Back in my days as a SQL server DBA, I didn't have many third-party tools at my disposal. I remember having a monitoring tool with licenses for only three or four SQL server instances. Whenever there was […]

During my technical career, I’ve changed companies several times. I even worked as an independent contractor for three years. One thing I have never done before was switch departments and roles within one company. That’s about to change in a couple of weeks as I move from Simple Talk Editor and DevOps Advocate in Marketing […]

You’ve probably heard that SQL Server 2022 is on the way, and, assuming the name doesn’t change, it will be later this year. That is great news for folks in the data platform community as features and improvements they’ve been hoping for are added. I’m not currently supporting any production SQL Servers, but I’m still […]

Some organizations have policies in place to make sure that everything in their IT infrastructure is documented. There are runbooks, procedures, wikis, diagrams, charts, code comments, and more to make sure that knowledge is available if an employee leaves or when disaster strikes.

I haven’t done it much the past few years, but I would answer some programming questions posted in forums back in the day. In the late 90s, I answered Visual Basic questions and eventually switched to SQL Server questions here on SQL Server Central as my career progressed. Answering questions not only assisted someone else, […]

Some of the most problematic T-SQL code I’ve seen over the years originated because the developer approached T-SQL with techniques more suitable for developing applications.

I’ve been teaching T-SQL to groups of students since 2014 at the non-profit LaunchCode in St. Louis. LaunchCode provides free tech training, paid apprenticeships, and career support to hundreds of people who have the ability and interest but not always the opportunity to land tech careers. For example, not having a college degree can eliminate […]

Back in the late 90s, I had one large book on my desk with everything I needed – or thought I needed -- to know about SQL Server. It covered T-SQL, installation, backups, security, and more. Over the years, Microsoft has added components like SQL Server Integration Services and features like windowing functions and improved […]
