Partition management operations not possible on non-partitioned table

Production Risk

Low — the ALTER TABLE will fail; no data is affected.

What this means

ER_PARTITION_MGMT_ON_NONPARTITIONED (1512, SQLSTATE HY000) is raised when partition management commands like ADD PARTITION, DROP PARTITION, or COALESCE PARTITION are used on a non-partitioned table.

Why it happens
  1. 1ALTER TABLE ADD PARTITION executed on a table without partitioning
  2. 2ALTER TABLE DROP PARTITION on a regular non-partitioned table
How to reproduce
trigger — this will error
trigger — this will error
CREATE TABLE t (id INT);
ALTER TABLE t ADD PARTITION (PARTITION p1 VALUES LESS THAN (100));
-- t is not partitioned

expected output

ERROR 1512 (HY000): Partition management on a non-partitioned table is not possible

Fix

First convert the table to a partitioned table

First convert the table to a partitioned table
ALTER TABLE t
PARTITION BY RANGE(id) (
  PARTITION p0 VALUES LESS THAN (100),
  PARTITION p1 VALUES LESS THAN MAXVALUE
);

-- Now partition management is possible:
ALTER TABLE t ADD PARTITION (PARTITION p2 VALUES LESS THAN (1000));

Why this works

The table must first be converted to a partitioned table before partition management operations can be applied.
