The column for a Geometric property can be overridden by attaching a Geometric column to it. Only the column name can be specified. The column type must always be mdsys.sdo_geometry.
The default column depends on whether the F_Geometry_0 table is present and whether the Geometric Property is also the GeometryProperty for its containing class.
If it is the GeometryProperty and F_Geometry_0 exists, then the table for this property is F_Geometry_<n>, where <n> is the ID of the Spatial Context Group for the associated Spatial Context. If the Geometric Property is not associated with a Spatial Context, then <n> is the ID of the active Spatial Context group, at the time the geometric property is created. The column for the property is always RDBMS_GEOM.
Otherwise, the column name is assumed to be the same as the property name. The column table is assumed to be the table for the containing class.
