    This post explains how you can create a ranking of data from an OLAP MDX query.

    December 15th, 2007 in Analysis Services, Blog, Reporting Services, SQL Server

    A number of our customers have reporting systems that use both MDX and SQL, retrieving data from both OLAP and SQL Server databases.
