2. Oracle Metalink has a note (69661.1) on how to determine type or table dependents of an object type.

The following 3 queries can be run to determine dependencies: ------------------------------------------------------------- -- Find nested tables select owner, parent_table_name, parent_table_column from dba_nested_tables where (table_type_owner, table_type_name) in (select owner, type_name from dba_coll_types where elem_type_owner = '' and elem_type_name = ''); -- Find VARRAYs select owner, parent_table_name, parent_table_column from dba_varrays where (type_owner, type_name) in (select owner, type_name from dba_coll_types where elem_type_owner = '' and elem_type_name = ' -- Find object tables select owner, table_name from dba_object_tables where table_type_owner = '' and table_type = '' and nested = 'NO';
