備註
The flag name may contain spaces. The natively-supported values are listed in the following table.
| Value | Description |
|---|---|
MODEL_EXISTENCE_ONLY |
The column should be modeled as having two states, missing and nonmissing, regardless of the values in the column. This is particularly useful for columns in a nested table, where values are sparse across cases. |
NOT NULL |
The column cannot accept NULL values. |
REGRESSOR |
The column supplies regressor values for test cases. |
Additional provider-specific flags may be used if third-party OLE DB or data mining providers have been aggregated on the instance of Microsoft SQL Server 2005 Analysis Services (SSAS).
A closely related element in the Analysis Management Objects (AMO) object model is MiningModelingFlags.
