Shredding XML in XEvents

One of the biggest pains with Extended Events is the thing we love to hate – XML. XML is so foreign to many DBAs. It’s not relational and often brings nightmares of parsing and performance issues.

Despite that, Extended Events takes advantage of XML much like we have seen in… Read more

Compressing Outcomes

You find yourself cruising along, just doing your thing as a database administrator. Then the CIO plops down into a spare chair in your cubicle to talk about the weather.

Well, not entirely true there. The CIO dropped in because the alerts for disk space have been blowing up everybody’s… Read more

Tables, Columns and Defaults Oh My!

Picture this if you could. You inherit a new database either through the change of a job, or finding a black box database server, or maybe due to the acquisition of a new application.

No matter the cause, you are now responsible for maintaining that database and you also really… Read more

Compressing Encrypted Backups

A common requirement, whether it be based out of pure want or truly out of necessity, is to make a large database backup file, that is encrypted, be much smaller.

This was a knock for the early days of Transparent Data encryption (circa SQL Server 2012). If TDE were enabled,… Read more

What is DBCC?

If I ask you what is DBCC, what would your answer be?

I want you to think about that one for just a little bit. What comes to mind when you hear DBCC? Is it the default go-to used when talking about consistency checks? Is it something more involved? Maybe… Read more

HealthySQL – A Review

How well do you know the health of your SQL Servers and databases? Ever wonder about the current health or even what the health was like a few months back? Sure, one could anecdotally say the databases and servers are healthy, but how do you quantify it?

Table Size Script Update for 2015

As was recently promised, I have an update to an old tried and true script for calculating the size of an object.

That promise was doled out in the previous article when I discussed the internal table types. You can read the article here. Information from that article was… Read more

Internal Tables and Space Used

Some of the beauty of SQL Server is the complexity that it holds. Some of that complexity is right before our eyes. And some of that requires a little bit of diving into the internals to figure out what is happening or even why it is complex.

I enjoy the… Read more

What’s the Size of that Index?

I have previously written about finding what the big space consumers are within the database. I even shared scripts in those articles on how to find those big consumers (read all about it here).

That is grand when it comes to quickly finding which objects happen to be… Read more

SQL Server and Defaults

What is that default setting?

SQL server does a fantastic job of having numerous settings at the server level and at the database level predefined for you. Additionally, the OS has a bunch of settings that are predefined. These are notoriously the default settings. Or as some would say: “Set… Read more

Database Settings Changes – Red Handed

One of my pet-peeves (and consequently frequent topic of discussion) is finding database settings (or any setting that has changed) without knowing about it. Worse yet is finding that the change has occurred and nobody claims to have any knowledge of it or having done the deed.

This happened again… Read more

Reading Extended Event File Session Data

Using Extended Events to trap/trace information allows the trapping of that information to various targets. One of the targets I will frequently tell people to use is the file target. The reasoning for this is the opportunity this affords to be able to review the output  at a later time… Read more

Execution Plans in Extended Events

Extended Events is a wonderful tool. Execution Plans are also some wonderful things – or are a wonderful tool as well. Both of these tools are fantastic for troubleshooting. Combined, they can potentially be even better.

Or, they could just cause some hair loss and be a fairly complicated pain… Read more
