Hello,

I have a tables called sales and I have created 12 (LIST) partititions for each of the business unit (id).

Now I want to add subpartitions on each of those partitions based on the year by using YEAR(report_date).

Below is the syntax I am trying

ALTER TABLE sales
MODIFY PARTITION sales_bu_p1
SUBPARTITION BY LIST (YEAR(report_date))
SUBPARTITIONS 4 (
PARTITION p2017 VALUES IN (2017),
PARTITION p2018 VALUES IN (2018),
PARTITION p2019 VALUES IN (2019),
PARTITION p2020 VALUES IN (2020)
);

But it is giving error (You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use)

Please help me in correting the syntax if anything is wrong.

Thanks in advance.

Regards
Pandit.P
