Question

Am I correct to think that listing indexes for materialized views is the same as listing indexes for tables? In other words:

select * 
  from ALL_IND_COLUMNS 
 where TABLE_OWNER='SOME_OWNER' 
   and TABLE_NAME='SOME_TABLE' 
 order by INDEX_NAME, COLUMN_POSITION;

Answer 1

It is, yes.

When you create a materialized view, you are actually creating a table of the same name as well. If you look at ALL_OBJECTS, you’ll see both a table and a materialized view with the same name

SELECT owner, object_name, object_type
  FROM all_objects
 WHERE owner = 'SOME_OWNER' 
   AND object_name = 'SOME_TABLE'
