創建表test_part_1 默認爲users表空間:
create table test_part_1(a number, b number)
partition by range(a)
(
partition p1 values less than (10),
partition p2 values less than (20),
partition p3 values less than (30),
partition p4 values less than (40)
);
創建test_part_1 本地索引
create index idx_id on test_part_1(a) local tablespace TS_KSZIP_BASE;
--插入記錄
insert into test_part_1 values(1,2);
insert into test_part_1 values(11,2);
insert into test_part_1 values(21,2);
insert into test_part_1 values(31,2);
commit;
--查看記錄
select rowid from test_part_1 where a=1;--AAAlz4AAEAAFTUEAAA 查詢1
--創建中間表
create table test_part_3(a number, b number);
create index idx_id3 on test_part_3(a);--默認表空間users
--test_part_1 與中間表交換
alter table test_part_1 exchange partition p1 with table test_part_3 including indexes with validation; --目標表有數據不能交換,交換隻能是分區和非分區表交換
--驗證
select * from dba_ind_partitions where index_name=upper('idx_id');--p1的表空間變成了users，並且狀態爲usable，不用rebuild
select * from dba_indexes where index_name=upper('idx_id3');--表空間變成了TS_KSZIP_BASE.
select rowid from test_part_3;--AAAlz4AAEAAFTUEAAA 跟查詢1對比可見 只是改了數據字典
--創建 目標分區表test_part_2
create table test_part_2(a number, b number)
partition by range(a)
(
partition p1 values less than (10),
partition p2 values less than (20),
partition p3 values less than (30),
partition p4 values less than (40),
partition p5 values less than (50)
);
create index idx_id2 on test_part_2(a) local tablespace TS_KSZIP_BASE;
alter table test_part_2 exchange partition p1 with table test_part_3 including indexes with validation; --目標表有數據不能交換,交換隻能是分區非分區交換
select * from dba_ind_partitions where index_name=upper('idx_id2');--索引p1可用,表空間依然是TS_KSZIP_BASE(因爲此時 idx_id3表空間爲TS_KSZIP_BASE)
select * from dba_indexes where index_name=upper('idx_id3');--表空間爲TS_KSZIP_BASE，狀態也是usable
