How make month wise partitioning in existing mysql table?

Question

I have a table with hundreds of thousands of records. How to partition the table, month-wise?

Answer 1

You can ALTER TABLE to create new PARITIONS on it.

ALTER TABLE table_name PARTITION BY RANGE (MONTH(date_column)
(
  PARTITION JAN VALUES LESS THAN (2),
  PARTITION FEB VALUES LESS THAN (3),
  ...
  PARTITION DEC VALUES LESS THAN MAXVALUE
);
