ColumnType (Level 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 ColumnType property of the Level interface contains the data type of the level member key column.

Applies To:clsAggregationLevel, clsCubeLevel, clsDatabaseLevel, clsPartitionLevel

Data Type

ADODB.DataTypeEnum

The ColumnType property is set to one of the following enumerated values.

Column type	Value
Big integer	adBigInt
Binary	adBinary
Boolean	adBoolean
String (Unicode)	adBSTR
Char	adChar
Currency	adCurrency
Date	adDate
Date	adDBDate
Time	adDBTime
Timestamp	adDBTimeStamp
Decimal	adDecimal
Double	adDouble
Integer	adInteger
Numeric	adNumeric
Single	adSingle
Small integer	adSmallInt
Tiny integer	adTinyInt
Unsigned big integer	adUnsignedBigInt
Unsigned integer	adUnsignedInt
Unsigned small integer	adUnsignedSmallInt
Unsigned tiny integer	adUnsignedTinyInt
Text (Unicode)	adWChar
Text	adChar

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 levels with automatic grouping (a level whose Grouping property is groupingAutomatic).

** Read-only for virtual cube levels and cube levels of a shared dimension (a parent Dimension object whose IsShared property is True).

注释

The ColumnType property determines how the server will bind the member key column. This property must be set to a compatible type or processing the dimension or cube will result in an error.

The ColumnSize property always returns adInteger for levels with a SubClassType of sbclsRegular, sbclsParentChild, sbclsLinked, or sbclsMining that use automatic grouping (that is, the Grouping property is groupingAutomatic). Additionally, this property always returns adVarChar for levels with a SubClassType of sbclsVirtual.

示例

Use the following code to specify an integer ColumnType:

' 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
