Où puis-je trouver les tablespaces de la partition d'intervalle dans le dictionnaire de données?

Question

Pour une table partitionnée intervalle de plage, vous pouvez spécifier plusieurs tablespaces comme:

CREATE TABLE range_part_interval_table(col1 NUMBER, col2 NUMBER) 
PARTITION BY RANGE (col1) 
INTERVAL (10) STORE IN (ts2, ts3, ts4) 
(PARTITION VALUES LESS THAN (100) TABLESPACE ts1); 

Mais je ne peux pas trouver où les tablespaces d'intervalle sont stockés dans le dictionnaire de données (ici, ts2, ts3, ts4). Cette information est-elle disponible quelque part?

Answer 1

Cela devrait vous obtenir les informations dont vous avez besoin:

SELECT table_owner, table_name, partition_name, tablespace_name 
FROM dba_tab_partitions 
WHERE table_name = <table_name>; 

Voici la description de la table:
