Oracle 创建索引分区

本地索引分区

-- 查看表的分区信息
SELECT INDEX_NAME, PARTITION_NAME, TABLESPACE_NAME FROM DBA_IND_PARTITIONS WHERE TABLESPACE_NAME = 'TABLESPACE_01';
SELECT INDEX_NAME, PARTITION_NAME, TABLESPACE_NAME FROM DBA_IND_PARTITIONS WHERE TABLESPACE_NAME = 'TABLESPACE_02';

-- 创建本地索引分区
CREATE INDEX RANGE_INDEX ON RANGE_TEST (ADD_TIME) LOCAL (
    PARTITION TABLE_01 TABLESPACE TABLESPACE_01,
    PARTITION TABLE_02 TABLESPACE TABLESPACE_02,
    PARTITION Y2018 TABLESPACE TABLESPACE_01
);

全局索引分区

-- 创建全局索引范围分区
CREATE INDEX RANGE_GLOBAL_INDEX ON RANGE_TEST (ID, ADD_TIME) GLOBAL PARTITION BY RANGE(ID) (
    PARTITION TABLE_01 VALUES LESS THAN (1000),
    PARTITION TABLE_02 VALUES LESS THAN (5000),
    PARTITION Y2018 VALUES LESS THAN (MAXVALUE)
);

-- 创建全局索引的HASH分区（设定为3个分区）
CREATE INDEX HASH_GLOBAL_INDEX ON HASH_TEST (ADD_TIME) GLOBAL PARTITION BY HASH(ADD_TIME) PARTITIONS 3;

管理索引分区

-- 删除全局索引，不能删除MAXVALUE分区
ALTER INDEX RANGE_GLOBAL_INDEX DROP PARTITION TABLE_01;
ALTER INDEX RANGE_GLOBAL_INDEX REBUILD PARTITION Y2018;
