Examples

Setting the DataType Property

The following example adds a new column to a data mining model object. It then sets various properties, including the DataType property.

'------------------------------------------------------------------------
' Add a new column to the mining model called Unit Sales and relate
' this column to the Sales cube measure of the same name. Set the
' column's data type to Integer, and identify the data content in it as
' being continuous and logarithmically normalized. Finally, identify this
' column as being predictable.
' Assume the existence of a DSO Cube object, dsoCb.
'------------------------------------------------------------------------
    'Add another column to the model.
    Set dsoColumn = dsoDmm.Columns.AddNew("Unit Sales")
    'Identify this column as being based on the Unit Sales measure.
    Set dsoColumn.SourceOlapObject = dsoCb.Measures("Unit Sales")
    'Identify the column type.
    dsoColumn.DataType = adInteger
    'Identify this column's content as being continuous.
    dsoColumn.ContentType = "CONTINUOUS"
    'Identify the statistical distribution of this data.
    dsoColumn.Distribution = "LOG_NORMAL"
    'Identify the column as being predictable.
    dsoColumn.IsPredictable = True
