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。

注意：
This property applies only to columns that belong to mining model objects of SubClassType sbclsRegular.

Access

Read/write for columns with a SubClassType of sbclsNested, read-only for all others.

备注

For columns with a SubClassType of sbclsRegular, this property returns the Filter property of the parent object. Columns can be nested, so the parent object can be either a clsMiningModel object or a clsColumn object.
