Question

I am selecting all tables from database by using query

select table_name from all_tables where owner='XYZ' order by table_name

But above query is also returning materialized view. How can I get only tables and not materialized view

Answer 1

you can ignore the materialized views and their log tables (if they exist) with

select *
  from all_tables t
 where owner = user
   and (owner, table_name) not in (select owner, mview_name
                                     from all_mviews l
                                   union all
                                   select log_owner, log_table
                                     from all_mview_logs)
