Bad Managers

I’m constantly hearing stories about terrible managers, and, of course, I’ve experienced quite a few myself. In fact, I can’t come up with many nice things to say about most managers when I look back over my career. (Luckily, my manager at Redgate is wonderful!) Early in my tech career, I was working at a […]

The SQL Community Steps up in Time of Need

Healthcare workers are some of the many heroes working bravely in the face of the Covid-19 pandemic. To protect themselves and their patients, they must wear face masks during their entire shifts. This causes a great deal of ear irritation, so a strap was designed to make wearing the masks easier and alleviate pressure on […]

Azure Data Studio and Deployment Notebooks

Azure Data Studio (ADS) is a cross-platform tool that you can use to run T-SQL queries much as you have done using SQL Server Management Studio. No, the databases do not need to be hosted in Azure; the tool works fine for on-premises SQL Servers as well. I’ve started using ADS more as I teach […]

The New Year: A Chance to Start Over

January 1st is the beginning of a new year thanks to Julius Caesar and Pope Gregory XIII. This date is somewhat arbitrary, and many religions and cultures celebrate their own beginning of a new year at different times. Even though these celebrations don’t fall at the same time, I think the sentiment is similar. The […]

How SQL Server Can Just Go Faster

It’s rare to get a call from a customer telling you that the application is fast today and thanks for taking such good care of the database. Instead, you are more likely to hear complaints when things go wrong like slow running queries and timeouts. There is a lot to consider when trying to figure […]

A Faster tempdb

I like to call tempdb the “workhorse” of SQL Server. I’ve heard some other people call it other terms that were not so flattering, but since I like to keep things positive, I’ll stick with workhorse. SQL Server uses tempdb for many things. The obvious uses are temp tables and table variables, but tempdb is […]

Which Service in Azure Should You Use for SQL?

I remember when Azure SQL Database was first released in 2010. Microsoft has tweaked the name a couple of times over the years, and back then it was called SQL Azure. The largest database you could create was just 50 GB, and there were quite a few restrictions, such as heaps not being supported. Since […]

Your chance to speak at PASS Summit

When I decided to switch careers about 25 years ago, I had no idea how far I would go in tech. I just wanted to leave the profession for which I had trained and become a developer. My goal was to make the switch by the end of 1998. It actually happened in the summer […]

SQL Server 2019 CTP 3.2 Available

Microsoft announced CTP 3.2 for SQL Server 2019 just a few days ago, but many people working with SQL Server don’t care about this. I run into people at user group meetings and SQL Saturdays who are stuck supporting versions as old as SQL Server 2000, and SQL Server 2008 R2 is still prevalent. I’m […]

SELECT UNISTR('%*3041%*308A%*304C%*3068 and good night', '%*') AS 'A Classic';
What is returned?
