EstimatedSize (Level Interface)

[!附註]

  下一版的 Microsoft SQL Server 將不再提供此功能。請勿在新的開發工作中使用此功能,並且儘速修改使用此功能的應用程式。

The EstimatedSize property of the Level interface contains the estimated number of members in the level object. This property is used by the partition analyzer when aggregations are designed.

Applies To:clsAggregationLevel, clsCubeLevel, clsDatabaseLevel, clsPartitionLevel

Data Type

Long

Access

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

clsDatabaseLevel

R/W

clsCubeLevel

R/W*

clsPartitionLevel

R

clsAggregationLevel

R

* Read-only for virtual cube levels.

備註

The EstimatedSize property is used during analysis of a partition when aggregations are designed. The value provided does not need to be precise, but it should be a close approximation.

[!附註]

  The EstimatedSize property for an (All) level is read-only and always set to one (1). This is also true for levels that belong to a virtual dimension created by Microsoft® SQL Server™ 7.0 OLAP Services.

範例

Use the following code to set the size and type values for a new level object:

' Assume an object (dsoDim) of ClassType clsDimension exists
Set dsoLev = dsoDim.Levels.AddNew("Store Id")
dsoLev.MemberKeyColumn = """store"".""store_number"""
dsoLev.ColumnSize = 4
dsoLev.ColumnType = adInteger
dsoLev.EstimatedSize = 24
