XLeratorDB/statistics Documentation

SQL Server statistical functions


XLeratorDB/statistics

Use XLeratorDB/statistics for a wide variety of statistical 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.

XLeratorDB/statistics is available in two packages - XLeratorDB/statistics which requires SQL Server 2005 or later, and XLeratorDB/statistics 2008 which requires SQL Server 2008 or later. 

Functions denoted with 'Not available for SQL2005' are only available in the XLeratorDB/statistics 2008 package and will not install or run  in SQL Server 2005. XLeratorDB 2008 packages contain functions which leverage SQL CLR features that are only available in SQL Server 2008 or later, namely 'multi-input aggregates' which provide a much easier calling syntax and typically run much faster than their scalar counterparts.
