The Ultimate Guide to High Availability with MariaDB

Is "LOCK=EXCLUSIVE" supported in "ALTER TABLE ... CONVERT TO" statement?

Dear community,

I get the following error:

MariaDB> ALTER TABLE events CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci LOCK=EXCLUSIVE;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'LOCK=EXCLUSIVE' at line 1

I haven't found anything in the documentation that this combination is not supported so it should work.

Any hint what have I overlooked?

MariaDB v10.5.15.

The options to lock are comma separated. So:

 ALTER TABLE events
CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci ,
LOCK=EXCLUSIVE;
