Description
If a table is created as MyISAM or ARIA engine or was at some point in the past converted to this engine type, a later conversion to INNODB and any subsequent ALTER TABLE statement produces the warning #1478. This is a critical bug as e.g. Ruby on rails interprets this warning as a failed transaction and does not apply DB migrations.
This can be reproduced using the following SQL:
CREATE DATABASE testdb; |
CONNECT testdb; |
CREATE TABLE testtable (id INT(11)) ENGINE=INNODB; |
ALTER TABLE testtable ENGINE=INNODB; |
ALTER TABLE testtable ENGINE=INNODB; |
ALTER TABLE testtable ENGINE=ARIA TRANSACTIONAL=1; |
ALTER TABLE testtable ENGINE=INNODB; |
SHOW WARNINGS;
|
ALTER TABLE testtable ENGINE=INNODB; |
SHOW WARNINGS;
|
Result:
MariaDB [(none)]> connect testdb;
|
Connection id: 6698
|
Current database: testdb
