Adam Machanic is coming up Thursday, June 21 to give the following presentation. As always please visit the eventbrite page for this meeting to RSVP so we can plan appropriately. This should be an excellent talk for DBAs, Developers and BI folks. Too many people aren’t taking advantage of these powerful functions – some of which have been available since SQL Server 2005…
T-SQL Power! The OVER Clause: Your Key to No-Sweat Problem Solving
Have you ever stared at a convoluted requirement, unsure of where to begin and how to get there with T-SQL? Have you ever spent three days working on a long and complex query, wondering if there might be a better way? Good news: The OVER clause, first introduced in SQL Server 2005 and greatly enhanced in SQL Server 2012, can be used to quickly and easily solve a number of problems that were previously very difficult or seemingly impossible. In this session you will learn to leverage aggregations and windowing operations to gain insight without losing information, enabling you to answer a number of interesting business problems with ease. Several demos will be shown to highlight the utility of the OVER clause for solving a large number of difficult–yet common–query problems, including custom paging schemes, data de-duplication, “top-N” problems, and complex statistical calculations. You will also learn how to creatively apply the feature to help with performance optimization of certain classes of tough queries. If you’re tired of writing queries that just don’t seem good enough, attend this session to get to the next level.
