Recompile hints have been tough to love in SQL Server for a long time. Sometimes it’s very tempting to use these hints to tell the optimizer to generate a fresh execution plan for a query, but there can be downsides.
I recently gave a day long session at the SQLPASS Summit called “SQL Server Index Therapy Session”. 61 people attended, and let me tell you I was thrilled with that number. I’ve co-presented lots of day and week long sessions, but this was the first day long session that I’d ever done solo at a conference and 61 people was a terrific number.

Here’s Microsoft’s overview of what the telemetry collects: https://www.microsoft.com/EN-US/privacystatement/SQLServer/Default.aspx
Working with table partitioning can be puzzling. Table partitioning isn’t always a slam dunk for performance: heavy testing is needed. But even getting started with the testing can be a bit tricky!
Here’s a (relatively) simple example that walks you through setting up a partitioned table, running a query, and checking if it was able to get partition elimination.
I’ve been thinking about taking up a new programming language as a hobby for a little while. There’s a vibrant software community here in Portland, and working in more languages than TSQL opens up lots more opportunities for fun. I have no intention of becoming a full-time Python programmer, I just believe it’s fun to code and good to challenge your brain in new ways.

You know how sometimes you learn something, then you start to see it everywhere you look?
I primarily work with SQL Server, but my favorite book on TSQL is the one that I learned with: The Transact SQL Cookbook.
One perk to filtered indexes that may not be obvious at first is that you get an extra “dimension”– almost an extra kind of key column. This can be useful for some queries that can be tricky to index.
Like anyone else, I easily get wrapped up in my own life: my family and friends, my work, my local community, my technical community. Facebook, Twitter, cat pictures. When I took time off from work recently, I got a glimpse outside of my normal, narrow world.
