Bug #: 50001324 (SQL Hotfix)



Notice
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.



SUMMARY
This article describes the following about this hotfix release:
 * The issues that are fixed by the hotfix package
 * The prerequisites for installing the hotfix package
 * Whether you must restart the computer after you install the hotfix package
 * Whether the hotfix package is replaced by any other hotfix package
 * Whether you must make any registry changes
 * The files that are contained in the hotfix package



SYMPTOMS
In Microsoft SQL Server 2005 Analysis Services, you have a cube that contains an unnatural hierarchy in a dimension. When you execute a Multidimensional Expressions (MDX) query against the cube and reference the hierarchy, the query unexpectedly does not return results. However, if you use the NON EMPTY keyword in the query, the query returns results as expected.



Hotfix information
A supported hotfix is now available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem. This hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next service pack that contains this hotfix.

To resolve this problem, submit a request to Microsoft Online Customer Services to obtain the hotfix. To submit an online request to obtain the hotfix, visit the following Microsoft Web site:

http://go.microsoft.com/?linkid=6294451

Note If additional issues occur or any troubleshooting is required, you might have to create a separate service request. The usual support costs will apply to additional support questions and issues that do not qualify for this specific hotfix.

Prerequisites

Restart information
You do not have to restart the computer after you apply this hotfix. However, this hotfix stops and then restarts the Analysis Services service. If you have configured Analysis Services for HTTP access, you must stop Internet Information Services (IIS) and then restart it after the installation is complete. If you have installed Analysis Services as a named instance, you must stop the SQL Server Browser service because the Msmdredir.dll component of the SQL Server Browser service is updated when you apply this hotfix.

Hotfix replacement information
This hotfix is not replaced by any other hotfixes.

Registry information
You do not have to change the registry.

File information
This hotfix contains only those files that are required to correct the issues that this article lists. This hotfix may not contain all the files that you must have to fully update a product to the latest build.

The English version of this hotfix has the file attributes (or later file attributes) that are listed in the following table.

WORKAROUND
To work around this issue, use one of the following methods:
 * If it is possible, do not use unnatural hierarchies.
 * Use the NON EMPTY keyword in the query.



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



MORE INFORMATION
You can use the NON EMPTY keyword to work around this problem.

Analysis Services cannot use &quot;dimension cube&quot; to determine which members have data. Therefore, Analysis Services must query the data in the actual cube.
