Microsoft distributes Microsoft SQL Server 2008 R2 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 2008 R2 fix release.
Consider the following scenario:
- You install Microsoft SQL Server 2008 R2 Analysis Services (SSAS 2008 R2).
- You create non-overlapping partitions in a measure group. The measure group contains a measure that uses the DistinctCount function.
Note Non-overlapping partitions are partitions that have non-overlapping value ranges.
- You define aggregations on the non-overlapping partitions.
- You run a multidimensional expression (MDX) query that queries the DistinctCount measure.
This issue occurs because the usage of an aggregation in the MDX query causes SSAS 2008 R2 to incorrectly scan the aggregation multiple times. This issue only occurs when you set up non-overlapping partitions that contain the DistinctCount measure.
