OceanBase CREATE TABLEGROUP

說明 
只有租戶下的管理員權(quán)限才可以創(chuàng)建表組。

CREATE TABLEGROUP [IF NOT EXISTS] tablegroupname [opt_tablegroup_option_list] [opt_tg_partition_option]

opt_tablegroup_option_list:
tablegroup_option [tablegroup_option]

tablegroup_option:
LOCALITY [=] locality_name
| PRIMARY_ZONE [=] primary_zone_name

opt_tg_partition_option:
PARTITION BY 
 HASH COLUMN_NUM [tg_subpartition_option] PARTITIONS INTNUM
| RANGE COLUMNS COLUMN_NUM [tg_subpartition_option] {PARTITION partition_name VALUES LESS THAN range_partition_expr, ...}
| LIST COLUMNS COLUMN_NUM [tg_subpartition_option] {PARTITION partition_name VALUES in list_partition_expr, ...}

tg_subpartition_option:
SUBPARTITION BY 
RANGE COLUMN_NUM SUBPARTITION TEMPLATE {SUBPARTITION partition_name VALUES LESS THAN range_partition_expr, ...}
| HASH COLUMN_NUM [SUBPARTITIONS INTNUM]
| LIST COLUMN_NUM SUBPARTITION TEMPLATE {SUBPARTITION partition_name VALUES in list_partition_expr, ...}
