Mar 14, 2012: Leaving the Windows Open

Jeremiah Peschka:
Leaving the Windows Open

    Jeremiah PeschaComputing running totals, averages by state or group, and other complex aggregations are not easy to implement in many relational databases. Thankfully, many relational databases include support for window functions. Window functions are an extension to the ANSI SQL standard. More than just another part of SQL, window functions enable complex ranking, ordering, and other aggregations over a subset of rows in a query. Understanding the capabilities of window functions lets you extend application functionality, build rich and complex queries, and reduce overhead in the application tier.

Jeremiah Peschka (Twitter) helps developers, DBAs, and engineers build faster, robust, and scalable solutions; Microsoft SQL Server is frequently a part of that solution, but other databases are also. He has worked as a database and emerging technology expert at Quest Software researching new trends and technologies around data storage. Before that Jeremiah worked across many industries as a system administrator, developer, and DBA, and has been involved in all aspects of application development and deployment.

Jeremiah is a principle with Brent Ozar -PLF.
