J'ai modifié la requête de WW pour fournir des informations plus détaillées:
SELECT * FROM (
SELECT
owner, object_name, object_type, table_name, ROUND(bytes)/1024/1024 AS meg,
tablespace_name, extents, initial_extent,
ROUND(Sum(bytes/1024/1024) OVER (PARTITION BY table_name)) AS total_table_meg
FROM (
-- Tables

segment_name AS table_name, bytes,
tablespace_name, extents, initial_extent
FROM dba_segments
WHERE segment_type IN ('TABLE', 'TABLE PARTITION', 'TABLE SUBPARTITION')
UNION ALL
-- Indexes
SELECT i.owner, i.index_name AS object_name, 'INDEX' AS object_type,
i.table_name, s.bytes,
s.tablespace_name, s.extents, s.initial_extent

WHERE total_table_meg > 10
ORDER BY total_table_meg DESC, meg DESC
