In all_objects
theres a a column called SUBOBJECT_NAME
, and the docs say that this is:
Name of the subobject (for example, partition)
If you do the following query:
select * from all_types where owner = 'MDSYS' and type_name = 'SDO_TGL_OBJECT_ARRAY'
You find that MDSYS.SDO_TGL_OBJECT_ARRAY
has a subobject called $VNS_1
. What is it? How can types have subobjects?
