My blog about SQL Server

In order for your SQL Server instance to run optimally, there are many SQL Server best practices that you need to follow. The SQL Health Check that you can have us perform on your instances looks at many of these. SQL Server 2016, which at the time of this writing is in a Release Candidate […]

Target. Home Depot. NASA. U.S. Army. Anthem. Wall Street Journal. MarketWired. Ashley Madison. What do they all have in common? They are all recent victims of cyber-attacks – several of these are confirmed to involve SQL Injection. Even though the exact method used to penetrate the other systems has not been released, experts believe that […]

In a prior post, I shared a script that will take a running trace and show you the XE events that it relates to, and what columns are available within those XE events. Specifically, this was for converting a deadlock trace into an XE session; however the process is the same for converting any trace […]

In this brave, new world of Extended Events (XE, XEvents), I find myself with a mixture of scripts for troubleshooting issues – some use XE, and some use traces. We’ve all been told that XE is a much better system (it is much more lightweight, causing less of an issue with the server). In fact, […]

I was recently reading this msdn article on Ghost Records, and it mentioned that you could get the number of ghost records on a page with DBCC DBTABLE… and it also mentioned that you need to be sure that you enable Trace Flag 3604 in order to see the results. So, two things immediately jumped […]

SQLSaturday SpeedPASSes I’ve been working with running SQLSaturdays in the Richmond, VA area for several years now. It seems that every year, I end up blogging something new. Frequently, this ends up being a script of some kind to help me out. This post follows this theme by introducing a script for working with SQLSaturday […]

While you may not need to worry about the physical location of a row very often, every so often the need comes up. In a few of my earlier posts (here), I have needed this information to prove a point. This post shows how to identify a row’s physical location. It will also show the […]

In several of my last few blog posts, I’ve shared several methods of getting internal information from a database by using the DBCC PAGE command and utilizing the “WITH TABLERESULTS” option to be allowed to automate this process for further processing. This post will also do this, but in this case, we’ll be using it […]

Today is yet another T-SQL Tuesday – the monthly blogging party started by Adam Machanic (b|t) to get everyone in the SQL Server blogosphere together and to blog about a topic. Today’s party is hosted by none other than Matt Gordon (b|t), and the topic that he has chosen for us to blog about is […]

In a prior blog post, I demonstrated how using DBCC PAGE can be automated by using the “WITH TABLERESULTS” option. In this post, we will continue with another look at how this can be done. On a nice wintry day, your city ended up being covered in several feet of snow. During the course of […]
