ALTER TABLE X.`click` PARTITION BY RANGE (UNIX_TIMESTAMP(CreatedAt))
PARTITIONS 4 (
PARTITION drop_old VALUES LESS THAN (UNIX_TIMESTAMP('2022-07-01')),
PARTITION p_20220801 VALUES LESS THAN (UNIX_TIMESTAMP('2022-08-01')),
PARTITION p_20220901 VALUES LESS THAN (UNIX_TIMESTAMP('2022-09-01')),
PARTITION future VALUES LESS THAN MAXVALUE);

CodePudding user response：

he manual has an example of how to use a timestamp in partitioning https://dev.mysql.com/doc/refman/8.0/en/partitioning-range.html for your example to work you need to change createdat datatype to timestamp.
