  • MDX Sub select Vs WHERE clause

    March 2nd, 2010 in Analysis Services, Blog

    I’ve just read an interesting thread on the SQL Server Developer Center forum, regarding how to filter results.

    April 21st, 2008 in Analysis Services, Blog, SQL Server

    One of the most frustrating limitations of SQL Server 2005 Standard edition is that it doesn’t support semi additive measures in SSAS Analysis Services cubes. This post explains a work around that provides similar functionality without having to shell out for the Enterprise Edition. What Are Semi Additive Measures?
