EstimatedSize (Level Interface)
Nota
Questa caratteristica verrà rimossa a partire dalla prossima versione di Microsoft SQL Server. Non utilizzare questa caratteristica in un nuovo progetto di sviluppo e modificare non appena possibile le applicazioni in cui è attualmente implementata.
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.
Class type |
Access |
|---|---|
clsDatabaseLevel |
R/W |
clsCubeLevel |
R/W* |
clsPartitionLevel |
R |
clsAggregationLevel |
R |
* Read-only for virtual cube levels.
Osservazioni
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.
Nota
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.
Esempio
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
