…………As I’ve cautioned before, I’m writing this series of amateur self-tutorials in order to learn how to use SQL Server to perform goodness-of-fit testing on probability distributions and regression lines, not because I already know the topic well. Along the way, one of the things I’ve… Read more
I’ve been a little remiss on this. I just haven’t been getting out to see people speak for a while (no travel is nice). However, I’m back in the airplane seats again, so these blog posts are off and running again.
Speaker of the Month for February 2016 is Jason… Read more
I had to do some performance testing for an MSSQLTips article and I thought I’d share the framework I used in a blog post.
First of all we have to log start and end dates of the package to a table so we can easily calculate the duration a package… Read more
I was talking with some of our support people recently about permissions on DLM Dashboard. A client was having issues, and we weren’t sure what was wrong. As a result, I decided to dig in a bit and see how limited I could be with permissions for the login/user that… Read more

I’ve used Windows Live Writer for almost as long as I’ve been blogging (mid 2007 or so). It’s worked well enough and I’ve liked having an offline editor. It moved to open source after years of stagnating (though it still worked well enough!) and I’ve finally moved to that version Read more
I presented a lightning round to the combined user groups on SQL Server Security Principals, which was a shortened version of a presentation I've given several times in the past. For this…
Even though an Azure SQL Database stores all data on the Azure cloud, it does not mean that your options for managing and monitoring the databases are limited compared to on-prem databases. In fact, the options available are very similar to on-prem, including 3rd-party products that support Azure SQL databases.… Read more
While working on the Advent of Code problems in SQL, I ran across something interesting. Day 4 involves hashing, which is done with the HASHBYTES function in SQL Server. This is a computation and given the problem, there is no good way to do this without brute force. The problem… Read more
It made me think…

Clearing out a full transaction log is a common problem. A quick search will find you dozens of forum entries and blog posts. Because of that I’m not going to talk about the correct methods of dealing with a transaction log full error. What I want to discuss is why… Read more
Earlier today I had the pleasure of speaking with the PASS Business Intelligence Virtual Chapter on getting started with Power BI and time calculations! There were a bit of audio issues on my end but thankfully we were able to still have a great event with lots of great questions! Read more

Sounds like something that clearly needs testing!
I’ll start with simple numbers table.
How much hospitals charge for the same type of cases compared with the average across the US and other cities around the world (limited data)?
The data used in this analysis may be old but it does give us a hint of how much more or less hospitals are charging… Read more
