SQL Cruise offers a number of unique opportunities for everyone involved, including speakers and sponsors. I’ve written before, several times, about the benefits of SQL Cruise. As an attendee of the cruise, you will get to sit in classes by amazing people (and me) talking about all aspects… Read more
I read all the time how SELECT * hurts performance. I even see where people have said that you just have to supply a column list instead of SELECT * to get a performance improvement. Let’s test it, because I think this is bunkum.
I have here two… Read more
A lot of the work around PASS currently is getting ready for Summit. I’m prepping my part in the keynotes. I’m involved in lots of community discussions including SQLSaturday, Chapters and Regional Mentors. We’re setting up the Community Zone for all sorts of activities throughout the week.… Read more
When you send a query to your SQL Server database (and this applies to Azure SQL Database, APS, and Azure SQL Data Warehouse), that query is going to go through… Read more
No one reads blogs any more.
Twitter is dying.
Facebook is broken.
G+. Is that even on any more?
Where do we go to share?
I’m seeing it here on this blog. Traffic is down. Not just day-to-day traffic, but the search hits. That could just be that… Read more
SQL Server is a deep and complex product. There’s always more to learn. For example, I had never heard of Correlated Datetime Columns. They were evidently introduced as a database option in SQL Server 2005 to help support data warehousing style queries (frequently using dates and times as join criteria… Read more
A few months ago I created a GitHub repository for the purpose of building and maintaining a list of resources for Azure Data Platform training. You can see it here. My goal in putting this into GitHub instead of just running it on my blog is to make it… Read more
I was just asked how many times I’ve been to the PASS Summit. This year will be my 12th consecutive one. That made me start thinking. At my very first Summit, I met a couple of volunteers for PASS (Allen Kinsel was one of them, I’ll blame him… Read more
PASS Summit 2016 is fast approaching. If you’re going, time to start making plans. If you’re not going, sell your boss on the idea and get registered. It’s only the largest Microsoft Data Platform event on the planet. There are over 200 sessions given by some of the most knowledgeable… Read more
Here’s a great question I received: We had a problem at 9:02 AM this morning, but we’re not sure what happened. Can Query Store tell us?
My first blush response is, no. Not really. Query Store keeps aggregate performance metrics about the queries on the database where Query Store is… Read more
If you’re working with Azure SQL Database or you’ve moved into SQL Server 2016, one of the biggest new tools is the Query Store. It provides a mechanism of capturing query performance over time and persisting it with the database. You also get the execution plans for those queries. Finally,… Read more
You get one clustered index per table.
That bears repeating, you get one clustered index per table.
Choosing a clustered index is an extremely important and fundamental aspect of all… Read more
Thursday at the PASS Summit is Kilt Day.
This means you should wear a kilt. Whether you do it in support of Women in Technology, or you just like to swan about in a kilt, this is the day to sport your kilt. Whether you have a fully traditional tartan Read more
I am endlessly fascinated by how the Query Store works. I love teaching it at every opportunity too. Plus, almost every time I teach it, I get a new question about the behavior that makes me delve into the Query Store just a little bit more, enabling me to better… Read more
Azure SQL Data Warehouse can sometimes feel like it’s completely different from SQL Server, but under the covers, it is still (mostly) SQL Server and it does have execution plans. Let’s take a look at one.
I’ve created a new SQL Data Warehouse using the sample database available on the… Read more
Time for another update.
The minutes for the June in-person meeting have been approved and are now ready for your information. We accomplished a lot in the two days and you can read what we did there. I’m pleased about two things. First, while it took until the July meeting… Read more
When the word comes around for elections to the PASS Board, are you one of those people who, even in passing, considers running? If you are, my advice is to well, do it.
By the way, here’s that word.
In order to make this a stronger, even more vibrant… Read more
I’m acting as the curator to a list of Azure Data Platform Learning Resources. It’s speakers and teachers, blogs, articles and more, all focused around the Azure Data Platform. I have it hosted on GitHub so that anyone can contribute. There have been several updates recently that you may… Read more
I love the Query Store. Seriously. It’s a huge leap forward in the capabilities of Azure SQL Database and SQL Server in support of performance monitoring and query optimization. One of my favorite aspects of the Query Store is the ability to force plans. Frankly though, it’s also the scariest… Read more
