AreKeysUnique (clsMiningModel)
The AreKeysUnique property of a clsMiningModel object indicates whether key columns (that is, a clsColumn object with an IsKey property set to True) defined in the Columns collection uniquely identify members in the case table.
Note This property applies only to mining model objects of SubClassType sbclsRelational.
Data Type
Boolean
Access
Read/write
Remarks
The AreKeysUnique property determines whether the relational mining model adds the DISTINCT keyword to the SQL SELECT query used to retrieve the training data set from the case tables. If the values for the key columns identified in the data mining model are unique in the case tables, setting this property to True can improve performance when the relational data mining model is trained.
