Do you ever need to use a text editor to apply regular expressions to files? If so, this post is for you! If not, you may wanna skip it and just return to it if you ever need it.
I recently got a great question: if I order by a column where all rows in that column have the same value, will SQL Server then order the results by the clustered index key?
I’m very that my session on table partitioning from the 2017 SQL PASS Summit is being featured as one of the “Best of Summit” videos.
I had a terrific time presenting this session, thanks to everyone in the audience: you were awesome!
You can watch the video here, and follow the link above to see even more great videos from the conference for free.
Woo hoo! I’ve just added a new course: Repeatable Read and Serializable Isolation Levels in SQL Server.
Update: even better news… courses are now open and free for all :smile:
I’ve just added a fresh new course: Indexing for Windowing Functions. Here’s the rundown: Windowing functions give you great flexibility for analyzing data in SQL Server. But how can you get the best performance for your windowing functions? In this 45 minute, demo-packed course, you will learn index design for windowing functions, when batch mode may be important, and how to compare the performance of Window Spool and Window Aggregate operators.
As we count down to the end of 2017, I’ve just scheduled a fresh batch of free, live webinars for 2018! Join me on Thursdays at 9 am Pacific / noon Eastern / 4 PM UTC.
A few folks have asked: will auto-tuning and adaptive query plans mean the end of performance tuning jobs for SQL Server? In this week’s episode, I talk about why I’m excited about those features rather than afraid of them.
Digging into this problem, I share the #1 mindset problem I had as a DBA, why this mindset is so common among database professionals, and a daily habit that can change your approach to new technology.
I had a great time this week talking about isolation levels with Hekaton – aka In-Memory OLTP – aka Memory Optimized tables. Here’s a video of the recorded webcast.
Last week’s Quizletter featured a quiz on keys vs included columns in SQL Server. I got a great question from a reader:
What do you consider a good reference and/or description of indexes for SQL Server? For example where would you have documentation that explains how the answer to #1 is right?
Are you worried that you talk too fast when you give a speech, talk, or presentation?
In this episode, I give you simple, practical tips that I’ve used to successfully improve the way I give presentations. Four years ago, I got frustrated feedback from listeners who had a hard time keeping up with my mouth; now I get congratulations that the pace was great.
