SQL Server windowing functions


XLeratorDB / windowing

Use XLeratorDB / windowing for a wide variety of windowing analytical calculations. The feature-rich XLeratorDB function library lets you include calculations in any T-SQL statement including SELECT, INSERT, UPDATE, DELETE, CREATE VIEW as well as in CTEs, stored procedures, user-defined functions, and computed columns.

The XLeratorDB / windowing functions provide windowing features to SQL Server 2005 and later that are not otherwise available in all versions of SQL Server.
