SQL & PL/SQL

Hi everyone,

I was wondering if any of you know a better way than mine to find the tablespace with the most indexes?

I made this query but maybe it can be done in another way?

SELECT DISTINCT tablespace_name
  FROM user_indexes
 WHERE tablespace_name IS NOT NULL
   AND index_type != 'DOMAIN'
 GROUP BY tablespace_name 
HAVING COUNT(*) >= (SELECT COUNT(*) 
                      FROM user_indexes
                     WHERE tablespace_name IS NOT NULL
                       AND index_type != 'DOMAIN'
                     GROUP BY tablespace_name 
                    );

Thanks
