ApsaraDB for OceanBase:Subpartition templates

Syntax of subpartition_template:

SUBPARTITION TEMPLATE
  ( { range_subpartition_desc [, range_subpartition_desc] ...
    | list_subpartition_desc [, list_subpartition_desc] ...
    | individual_hash_subparts [, individual_hash_subparts] ...
    }
  ) | hash_subpartition_quantity

Defining subpartition templates by using the SUBPARTITION TEMPLATE keywords are supported. The syntax in the template is the same as that of user-defined partitions. For more information, see User-defined partitions. Sample code:

CREATE TABLE 
T (C1 DATE, C2 NUMBER)PARTITION BY RANGE (C1) SUBPARTITION BY RANGE (C2)
SUBPARTITION TEMPLATE 
(SUBPARTITION SP_TEMP VALUES LESS THAN (999))
(
  PARTITION SALES_Q1_1998 VALUES LESS THAN (TO_DATE('01-APR-1998','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN')),
  PARTITION SALES_Q3_1999 VALUES LESS THAN (TO_DATE('01-OCT-1999','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN')),
  PARTITION SALES_Q2_2000 VALUES LESS THAN (TO_DATE('01-JUL-2000','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN')),
  PARTITION SALES_Q3_2000 VALUES LESS THAN (TO_DATE('01-OCT-2000','DD-MON-YYYY', 'NLS_DATE_LANGUAGE=AMERICAN')),
  PARTITION SALES_Q4_2000 VALUES LESS THAN (MAXVALUE)
  );
