BUG #: 445 (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.
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
When you run a Multidimensional Expressions (MDX) query against a measure group in Microsoft SQL Server 2005 Analysis Services, you experience the following symptoms:
- The MDX query takes much longer than you expect to run. For example, a query that you expect to take approximately 12 seconds to run may take approximately 4 minutes to run.
- If you run a SQL Server Profiler trace to trace the query execution, you determine that Analysis Services incorrectly reads data from the partitions instead of from the aggregations.
This problem occurs if the following conditions are true:
- You run a Process Incremental operation on one or more of the partitions in the measure group that you query.
You run an MDX query that resembles the following.
select filter([Measures].members, [Measures].currentmember.member_caption = [Measures].currentmember.member_caption) on columns from [Adventure Works]
Note If you run a Process Index operation on the partitions on which you ran the Process Incremental operation, this problem does not occur.
CAUSE
This problem occurs because of a code problem in Analysis Services. A dimension may have lazy processing enabled. This is when the ProcessingMode property is set to the LazyAggregations value. Additionally, the AttributeRelationship value of this dimension may have the RelationshipType property set to the Flexible value. If you run a Process Update operation on this dimension without also running a Process Index operation, Analysis Services drops the flexible aggregations. Additionally, Analysis Services does not rebuild the aggregations.

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