CREATE TABLE tbl_key_range
(
    col1 INT,
    col2 INT,
    col3 varchar(20),
    col4 DATE
)
PARTITION BY KEY(col1)
    SUBPARTITION BY RANGE COLUMNS(col4)
(
  PARTITION  p0(
    SUBPARTITION p0_q1_2023 VALUES LESS THAN('2023-04-01'),
    SUBPARTITION p0_q2_2023 VALUES LESS THAN('2023-07-01'),
    SUBPARTITION p0_q3_2023 VALUES LESS THAN('2023-10-01'),
    SUBPARTITION p0_q4_2023 VALUES LESS THAN('2024-01-01')
  ),
  PARTITION  p1(
    SUBPARTITION p1_q1_2023 VALUES LESS THAN('2023-04-01'),
    SUBPARTITION p1_q2_2023 VALUES LESS THAN('2023-07-01'),
    SUBPARTITION p1_q3_2023 VALUES LESS THAN('2023-10-01'),
    SUBPARTITION p1_q4_2023 VALUES LESS THAN('2024-01-01')
    ),
  PARTITION  p2(
    SUBPARTITION p2_q1_2023 VALUES LESS THAN('2023-04-01'),
    SUBPARTITION p2_q2_2023 VALUES LESS THAN('2023-07-01'),
    SUBPARTITION p2_q3_2023 VALUES LESS THAN('2023-10-01'),
