Bug #: 50002006 (SQL Hotfix)



Microsoft distributes Microsoft SQL Server 2005 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release.



SYMPTOMS
Consider the following scenario. In Microsoft SQL Server 2005 Analysis Services (SSAS), you create a dimension that contains one regular hierarchy and one parent/child hierarchy. You create some Multidimensional Expressions (MDX) queries. You discontinuously run the same MDX queries. These queries cross both hierarchies against the dimension. In this scenario, unexpected results may be returned.



CAUSE
SSAS uses a cache to store the query results. This problem occurs because SSAS reads data from the cache that contains all previous results of the queries when you run the query again.



RESOLUTION
The fix for this issue was first released in Cumulative Update 5. For more information about how to obtain this cumulative update package for SQL Server 2005 Service Pack 2, click the following article number to view the article in the Microsoft Knowledge Base:

943656 Cumulative update package 5 for SQL Server 2005 Service Pack 2

Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release. Microsoft recommends that you consider applying the most recent fix release that contains this hotfix.

Microsoft SQL Server 2005 hotfixes are created for specific SQL Server service packs. You must apply a SQL Server 2005 Service Pack 2 hotfix to an installation of SQL Server 2005 Service Pack 2. By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
