AggregationPrefix

The AggregationPrefix property of the MDStore interface contains the prefix associated with an aggregation in an MDStore object.

Applies To

Aggregation prefixes are used to generate aggregation names, and are used for table names in the relational database.

A fully-expanded aggregation name has four parts:

<DatabasePrefix><CubePrefix><PartitionPrefix><AggregationID>

The first three parts of the name are user-provided and make up the aggregation prefix; the fourth part of the name is a system-defined ID over which users have no control. The first two prefixes (DatabasePrefix and CubePrefix) are optional. CubePrefix is used only if PartitionPrefix begins with “+”, and DatabasePrefix is used only if CubePrefix begins with “+”. For example, if PartitionPrefix is “+_Partition1”, CubePrefix is “+_1995”, and DatabasePrefix is “Sales”, the aggregation prefix is “Sales_1995_Partition1”.
