I have a need to filter some annotation from related tables. I would like to left outer join an annotation feature class to a different featureclass, add a where clause and keep only the fields from the original annotation feature class and register it with geodatabase as an annotation featureclass. When I do so, it reads the shape as polygon and registers it as a polygon feature class. I would like to keep the annotation class extension on the feature class. Is there a trick to doing this? Like some SDE table to update or a field to add.
