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.

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.

In order to be able to take data from a variety of sources, manipulate it, and then export it to one of several destinations, SSIS has to use its own data types. If you hit problems, then you may need to intervene to ensure an appropriate conversion.

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?

Use the power of regular expressions to cleanse your data right there inside the Data Flow. This transformation includes a full user interface for simple configuration, as well as advanced features such as error output configuration. Two regular expressions are used, a match expression and a replace expression. The transformation is designed around the named capture groups or match groups, and even supports multiple expressions.

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?

Sometimes, you can tire of writing the same PowerShell code once again. After this happened to Phil whilst keying in an SMO pipeline to access databases, it occurred to him that he should have only one pipeline to access databases in PowerShell, one reusable pipeline

Service Broker is a technology built into SQL Server and utilized by the engine for its internal asynchronous processing. The great thing about Service Broker is that its functionality is exposed so we can build our own custom data integrations. Deanna Dicken introduces you to the concepts needed to create a service broker integration.
