Partitions to reorganize must be consecutive

Production Risk

Low — the ALTER TABLE fails; no data is affected.

What this means

ER_CONSECUTIVE_REORG_PARTITIONS (1526, SQLSTATE HY000) is raised when REORGANIZE PARTITION lists partitions that are not consecutive in the partition order.

Why it happens
  1. 1REORGANIZE PARTITION specifying non-adjacent partitions
  2. 2Skipping partitions in the REORGANIZE list
How to reproduce
trigger — this will error
trigger — this will error
ALTER TABLE t REORGANIZE PARTITION p0, p2 INTO (
  PARTITION pnew VALUES LESS THAN (300)
);
-- p0 and p2 are not consecutive (p1 is between them)

expected output

ERROR 1526 (HY000): When reorganizing a set of partitions they must be consecutive

Fix

Include all consecutive partitions in the REORGANIZE

Include all consecutive partitions in the REORGANIZE
ALTER TABLE t REORGANIZE PARTITION p0, p1, p2 INTO (
  PARTITION pnew VALUES LESS THAN (300)
);

Why this works

REORGANIZE PARTITION requires that all listed partitions are adjacent in the partition sequence.
