Using DELETE CASCADE Option for Foreign Keys
Referential integrity is a very important thing to consider when designing a database. In my years as a DBA I've seen database designs that sit on both ends of the spectrum, none at all and cases where every table is linked to multiple tables. While the later certainly can be a little more difficult to work with it ensures the integrity of your data stays intact. The other end provides much more flexibility when it comes to updating and deleting data from your database, whether it's being done through the application or directly on the backend, but has the issue of possible orphan records if things are not done properly. This tip will look at the DELETE CASCADE option when creating foreign key constraints and how it helps keep the referential integrity of your database intact.

Regular Expression Transformation
The regular expression transformation exposes the power of regular expression matching within the pipeline. One or more columns can be selected, and for each column an individual expression can be applied. The way multiple columns are handled can be set on the options page.

Removing the SQL Server Management Data Warehouse
SQL Server 2008 introduced a new feature, Management Data Warehouse (MDW), which allows users to collect metrics on their servers over time to aid in performance troubleshooting. A lot of people try this feature out, because it is easy to set up, and then find that it is not so easy to remove. In fact, removing MDW is not supported; in SQL Server 2012, though, a new system stored procedure was added to make this process easier. The problem is that this stored procedure (as well as several of the workarounds I've seen published) can leave several objects behind.

Optimizing tempdb configuration with SQL Server 2012 Extended Events
One of the most obvious bottlenecks in the performance of tempdb is caused by PAGELATCH, in-memory latch contention on the allocation bitmap of each data file used. We can use one of the rules-of-thumb to choose what should be roughly the best number of files, but how then do you check to see whether you've got it right for your data and workload?

Issues Determining an Individual SQL Server User's Permissions
Recently I was supporting a third party application. It queries to determine what tables it has permissions to before it proceeds with the rest of its functionality. We had implemented permissions based on the best practice of creating roles, assigning the permissions to the roles, and then making the users members of the roles. The application was querying INFORMATION_SCHEMA.TABLE_PRIVILEGES and of course didn't find any permissions directly against the user in question. We ended up granting explicit permissions to the user so the application would work, but I'm more interested in the general case. How can I determine permissions for an individual user?
