SQL Server 2012 (RC0 available here) has introduced new analytic functions. These functions were long awaited and I am glad that they are now here. Before when any of these functions was needed, people used to write long T-SQL code to simulate these functions. But now, there’s no need of doing so. Having available native function helps performance as well as readability.
In the last few days, I have written many articles on this subject on my blog. The goal was to make these complex analytic functions easy to understand and make them widely accepted. As these new functions are available and as awareness spreads about them, we should start using these new functions. Here is a quick list of the new functions and relevant MSDN sites:
I also enjoyed three different puzzles during the course of this series which gave a clear idea about the SQL Server 2012 analytic functions.
This series will always be my dear series as during this series I had went through a very unique experience of my book going out of stock and becoming available after 48 hours.
