使用示例

RANGE-LIST类型的使用示例

CREATE TABLE tbl_range_list (col1 INT, col2 INT, col3 varchar(20))
PARTITION BY RANGE(col1)
    SUBPARTITION BY LIST(col2)
(
  PARTITION m1 VALUES LESS THAN(1000) (
    SUBPARTITION p0 VALUES in (1, 2),
	SUBPARTITION p1 VALUES in (3, 4),
	SUBPARTITION p2 VALUES in (5, 6)
  ),
  PARTITION m2 VALUES LESS THAN(2000) (
    SUBPARTITION p3 VALUES in (1, 2),
	SUBPARTITION p4 VALUES in (3, 4),
	SUBPARTITION p5 VALUES in (5, 6)
  ),
  PARTITION m3 VALUES LESS THAN(MAXVALUE) (
    SUBPARTITION p6 VALUES in (1, 2),
	SUBPARTITION p7 VALUES in (3, 4),
	SUBPARTITION p8 VALUES in (5, 6)
  )
);

RANGE COLUMNS-LIST类型的使用示例

CREATE TABLE tbl_range_columns_list
(
    col1 INT,
    col2 INT,
    col3 varchar(20),
    col4 DATE
)
PARTITION BY RANGE COLUMNS(col4)
	SUBPARTITION BY LIST(col1)
(
  PARTITION dp1 VALUES LESS THAN('2023-01-01')(
    SUBPARTITION p0 VALUES in (1, 2),
    SUBPARTITION p1 VALUES in (3, 4),
    SUBPARTITION p2 VALUES in (5, 6)
  ),
  PARTITION dp2 VALUES LESS THAN('2024-01-01')(
    SUBPARTITION p3 VALUES in (1, 2),
    SUBPARTITION p4 VALUES in (3, 4),
    SUBPARTITION p5 VALUES in (5, 6)
  ),
  PARTITION dp3 VALUES LESS THAN('2025-01-01')(
    SUBPARTITION p6 VALUES in (1, 2),
    SUBPARTITION p7 VALUES in (3, 4),
    SUBPARTITION p8 VALUES in (5, 6)
  )
);
