Description

With the 2005 and 2012 releases of SQL Server, Microsoft gave us several new functions with amazing capabilities. These functions are part of the ANSI standards, and have nothing to do with the Windows OS. Some of these functions are well known, for example ROW_NUMBER is used by many people. In addition to ROW_NUMBER, we now have the ability to calculate summaries without changing a query to an aggregate query, calculate running totals, pull values from other rows, and perform statistical calculations. This course covers all of the available window functions including syntax, real world examples, and performance considerations.
