ALTER TABLE .. ADD PRIMARY KEY IF NOT EXISTS -> ERROR 1068 (42000): Multiple primary key defined

    Details

    • Sprint:
      10.0.22

      Description

      MariaDB [test]> CREATE TABLE `market_deductions` (
          ->   `event_id` bigint(20) unsigned NOT NULL DEFAULT '0',
          ->   `market_id` bigint(20) unsigned NOT NULL DEFAULT '0',
          ->   PRIMARY KEY (`event_id`,`market_id`)
          -> ) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC;
      Query OK, 0 rows affected (0.01 sec)
       
      MariaDB [test]>  ALTER TABLE market_deductions ADD PRIMARY KEY IF NOT EXISTS event_id (event_id,market_id);
      ERROR 1068 (42000): Multiple primary key defined

      Seems IF NOT EXISTS is not really checked.

      Haven't checked if 10.0.22 has fixed this as part of MDEV-8212
