OpenRecordset(query)
Returns a recordset (the Recordset object) containing records of the query connected with the feature. The type of the feature must be linked with the root table of the query (link descriptor based on the root table must belong to the FeatureType::DataLinks collection) or directly linked with the cataloged query from an external database (link descriptor based on the cataloged query from an external database must belong to the FeatureType::DataLinks collection). The return recordset is in the active state (see the Recordset::IsActive property).
