day11_分区表------子分区的母模板(10g)

create table t_test_subtemplate( rec_type varchar2(10), capture_time date, uuid number)partition by range(capture_time)subpartition by list(uuid)subpartition template( subpartition sub_10 values(1, 2, 3, 4, 5, 6, 7, 8, 9, 10), subpartition sub_20 values(11, 12, 13, 14, 15, 16, 17, 18, 19, 20), subpartition sub_30 values(21, 22, 23, 24, 25, 26, 27, 28, 29, 30), subpartition sub_40 values(31, 32, 33, 34, 35, 36, 37, 38, 39, 40), subpartition sub_50 values(41, 42, 43, 44, 45, 46, 47, 48, 49, 50), subpartition sub_60 values(51, 52, 53, 54, 55, 56, 57, 58, 59, 60))( partition part_201101 values less than(to_date('20110131', 'YYYYMMDD')));
如上，subpartition template会建立一个子分区的模板，接下来添加分区不必指定子分区，oracle会根据模板创建子分区。执行以下语句查看子分区情况：select table_name, partition_name, subpartition_name from user_tab_subpartitions;
结果如下：TABLE_NAME PARTITION_NAME SUBPARTITION_NAME ------------------------------ ------------------------------ ------------------------------ T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_10 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_20 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_30 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_40 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_50 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_60
添加分区：alter table t_test_subtemplate add partition part_201102 values less than(to_date('20110228', 'YYYYMMDD'));再次查看子分区情况：TABLE_NAME PARTITION_NAME SUBPARTITION_NAME ------------------------------ ------------------------------ ------------------------------ T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_10 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_20 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_30 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_40 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_50 T_TEST_SUBTEMPLATE PART_201101 PART_201101_SUB_60 T_TEST_SUBTEMPLATE PART_201102 PART_201102_SUB_10 T_TEST_SUBTEMPLATE PART_201102 PART_201102_SUB_20 T_TEST_SUBTEMPLATE PART_201102 PART_201102_SUB_30 T_TEST_SUBTEMPLATE PART_201102 PART_201102_SUB_40 T_TEST_SUBTEMPLATE PART_201102 PART_201102_SUB_50 T_TEST_SUBTEMPLATE PART_201102 PART_201102_SUB_60
