備註

The following updates to a mining model may require that the model be reprocessed. In general, the model must always be reprocessed when the change to the model or to the properties of the model columns results in a DDL ALTER statement:

  • Adding or removing columns.

  • Changing column usage.

  • Changing the algorithm parameter values.

  • Changing the algorithm.

  • Any AMO Update statement.

The following updates do not require reprocessing, but the model must be rebuilt and redeployed:

  • Changing a model name or description.

  • Changing column name or description.
