ColumnSize (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 ColumnSize property of the Level interface contains the size (in bytes) of the members in the level aggregation column in an aggregation table.
Applies To:clsAggregationLevel, clsCubeLevel, clsDatabaseLevel, clsPartitionLevel
Data Type
Integer
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 and cube levels of a shared dimension (a parent Dimension object whose IsShared property is True).
Osservazioni
The ColumnSize property always returns 0 for (All) levels (that is, levels whose LevelType property is levAll) with a SubClassType of sbclsRegular, sbclsParentChild, sbclsLinked or sbclsMining, and for levels whose LevelType property is set to sbclsVirtual.
Set ColumnSize to be large enough to store the data type of the level. Integer values, for example, require a minimum of four bytes. If the level contains string values, find the length of the member with the longest string. Set ColumnSize greater than or equal to the length of that string multiplied by the byte size of an individual character. The ColumnSize property cannot be set to zero.
Esempio
Use the following code to specify a column size of 40:
'Assume an object (dsoLev) of ClassType clsDatabaseLevel exists
dsoLev.ColumnSize = 40
