IsDefault (MDStore Interface)

注意：
下一版本的 Microsoft SQL Server 将删除该功能。请不要在新的开发工作中使用该功能，并尽快修改当前还在使用该功能的应用程序。

The IsDefault property of the MDStore interface indicates that an MDStore object is the default partition of a cube or the default aggregation of a partition.

Applies To:clsAggregation, clsPartition

Data Type

Boolean

Access

Access depends on the value of the ClassType property of the object.

Class type	Access
clsAggregation	R/W
clsPartition	R

备注

The default value for this property depends on the value of the ClassType property of the object.

Class type	Default value
clsAggregation	If you generate the aggregation by using an object of ClassType clsPartitionAnalyzer, the system automatically sets IsDefault to True. Generating aggregations in this way has performance benefits and is the recommended method for generating aggregations. If you generate the aggregation without using a partition analyzer object, you should set IsDefault to False.
clsPartition	True if the partition is the only one in the cube, False otherwise.

注意：

This property does not indicate that an aggregation object is the default within a collection of aggregations. If set to True, it indicates that the aggregation object contains the default dimensions and measures of the partition, which are already stored in the repository. This reduces the size of aggregation metadata, which can become important when a partition contains a large number of aggregations.
