In a recent post, I introduced you to how to work with the registry directly from within SQL Server. Continuing this theme, this post provides an example situation where you would do so. In this example, we will want to configure SQL Server to enable a few trace flags (TF) when SQL Server starts. Specifically, […]

There is a lot of information within the Windows registry. Sometimes, it would sure be nice to work with the registry within your T-SQL scripts. As it turns out, there are a bunch of undocumented extended stored procedures that do just this. A listing of these procedures are: As you can see, there are two […]
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 […]
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 […]
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 […]
Way back in 2006, Paul Randal documented DBCC PAGE on his Microsoft blog at //blogs.msdn.com/b/sqlserverstorageengine/archive/2006/06/10/625659.aspx. In his post, you will notice that in order to return the output from DBCC PAGE to the screen, you need to enable trace flag 3604 first. The above blog post shows a few examples of the results and utilizing […]
