对于范围间隔分区表，您可以指定多个表空间，例如：
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);
但我找不到区间表空间在数据字典中的存储位置（此处为ts2, ts3, ts4）。这些信息在某处可用吗？
这应该可以为您提供所需的信息：
SELECT table_owner, table_name, partition_name, tablespace_name
FROM dba_tab_partitions
WHERE table_name = <table_name>;
以下是表格说明：
%> desc dba_tab_partitions
Name Null Type

直到你有一些数据，你的间隔分区才存在......
SQL> CREATE TABLE range_part_interval_table(col1 NUMBER, col2 NUMBER)
2 PARTITION BY RANGE (col1)
3 INTERVAL (10) STORE IN (ts2, ts3, ts4)
4 (PARTITION VALUES LESS THAN (100) TABLESPACE ts1);
Table created.
SQL> SELECT table_owner, table_name, partition_name, tablespace_name
2 FROM dba_tab_partitions
3 WHERE table_name = 'RANGE_PART_INTERVAL_TABLE'
4 /

空表只有定义的分区。但是如果我们为不同的时间间隔插入一些数据......
SQL> insert into range_part_interval_table values (90, 8888)
2 /
1 row created.
SQL> insert into range_part_interval_table values (110, 8888)
