Lister la taille des blobs partitionnés

La requête suivant permet de te lister la taille des partitions qui contiennent des LOBS  :

 

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME,PARTITION_NAME,ROUND(SUM(DS.BYTES)/(1024 * 1024)) AS MB
FROM DBA_SEGMENTS DS
WHERE
DS.TABLESPACE_NAME not in ('SYSAUX','SYSTEM')
AND
SEGMENT_TYPE='LOB PARTITION'
GROUP BY DS.TABLESPACE_NAME,SEGMENT_NAME,PARTITION_NAME
ORDER BY 4;

La requête suivante permet de te lister la taille des partitions pour le segment TOTO : 

SELECT DS.TABLESPACE_NAME, SEGMENT_NAME, ROUND(SUM(DS.BYTES) / (1024 * 1024)) AS MB
FROM DBA_SEGMENTS DS
WHERE SEGMENT_NAME ='TOTO'
GROUP BY DS.TABLESPACE_NAME,
SEGMENT_NAME;
