I have tables and feature classes in an Oracle 12c geodatabase (10.7.1).

I would like to generate a list of tables and feature classes that have subtypes defined in them.

Is there a way to do this with SQL?


select       
     i.name as table_name
    ,extractvalue(definition_xml.column_value, 'DEFeatureClassInfo/SubtypeFieldName') as subtype_field_name
    ,it.name || ' [sub type]' as item_type
from        
     sde.gdb_items_vw i 
inner join 
    sde.gdb_itemtypes it 
    on i.type = it.uuid
cross join 
    table(xmlsequence(xmltype(definition).extract('/DEFeatureClassInfo'))) definition_xml
where        
      extractvalue(definition_xml.column_value, 'DEFeatureClassInfo/SubtypeFieldName') is not null
      --and i.name = 'YOUR_OWNER.YOUR_FEATURE_CLASS'
      and rownum <= 109

Note: The XML in the GDB_ITEMS_VW seems to have problems.

The query above works for the first 109 rows. But fails if 110 rows are returned:

ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00007: unexpected end-of-file encountered
ORA-06512: at "SYS.XMLTYPE", line 272
ORA-06512: at line 1

I don't know what the cause is. Maybe it just doesn't like the last record in the result set.
