Create a subpartitioned table

Subpartitioning is a technique that partitions a table in two dimensions. For example, it is frequently used in scenarios that involve bills.

Subpartitioning types

OceanBase Database in MySQL mode supports the HASH, RANGE, LIST, KEY, RANGE COLUMNS, and LIST COLUMNS partitioning types, and a combination of any two of them can be used for subpartitioning. The following table describes the support for subpartitioned table creation.

Create a subpartitioned table

When you create a subpartitioned table, you can choose whether to use a template.

SQL syntax to create a subpartitioned table by using a template

CREATE TABLE [IF NOT EXISTS] table_name(column_option_list)
  partition_option_list;

column_option_list:
  column_name column_type [, column_name column_type]

partition_option_list:
PARTITION BY
  RANGE {(expression) | COLUMNS (column_name_list)}{subpartition_option} (range_partition_list)
 | LIST {(expression) | COLUMNS (column_name_list)}{subpartition_option} (list_partition_list)
 | HASH(expression) {subpartition_option} { (hash_partition_list)
                                           | PARTITIONS partition_count }
 | KEY(column_name_list) {subpartition_option} { (key_partition_list)
                                                | PARTITIONS partition_count }

subpartition_option:
  SUBPARTITION BY
     RANGE {(expression) | COLUMNS (column_name_list)} SUBPARTITION TEMPLATE (range_subpartition_list)
    | LIST {(expression) | COLUMNS (column_name_list)} SUBPARTITION TEMPLATE (list_subpartition_list)
    | HASH(expression) { SUBPARTITION TEMPLATE (hash_subpartition_list)
                       | SUBPARTITIONS subpartition_count}
    | KEY(column_name_list) { SUBPARTITION TEMPLATE (key_subpartition_list)
                            | SUBPARTITIONS subpartition_count}

range_partition_list:
    range_partition [, range_partition ...]

range_partition:
    PARTITION partition_name VALUES LESS THAN {(expression_list) | MAXVALUE}

range_subpartition_list:
    range_subpartition [, range_subpartition ...]

range_subpartition:
    SUBPARTITION subpartition_name VALUES LESS THAN {(expression_list) | MAXVALUE}

list_partition_list:
    list_partition [, list_partition ...]

list_partition:
    PARTITION partition_name VALUES IN {(expression_list) | DEFAULT}

list_subpartition_list:
    list_subpartition [, list_subpartition ...]

list_subpartition:
    SUBPARTITION subpartition_name VALUES IN {(expression_list) | DEFAULT}

hash_partition_list:
    hash_partition [, hash_partition ...]

key_partition_list:
    key_partition [, key_partition ...]

hash_partition | key_partition:
    PARTITION partition_name

hash_subpartition_list:
    hash_subpartition [, hash_subpartition ...]

key_subpartition_list:
    key_subpartition [, key_subpartition ...]

hash_subpartition | key_subpartition:
    SUBPARTITION subpartition_name

expression_list:
    expression [, expression ...]

column_name_list:
    column_name [, column_name ...]

partition_count | subpartition_count:
    INT_VALUE

Note

• When you use a template to create a subpartitioned table, the template defines subpartitions under each partition. In this case, subpartitions under each partition share the same definition.
• For a template-based subpartitioned table, the subpartitions are named in the format of ($part_name)s($subpart_name). For the tbl_rr table in the following example, the p0 partition has three subpartitions: p0smp1, p0smp2, and p0smp3.

obclient> CREATE TABLE tbl_rr(col1 INT,col2 INT,col3 INT)
       PARTITION BY RANGE(col1)
