## Erreur 1005
si l'on rencontre ce type d'erreur :
ERROR 1005 (HY000) at line 13: Can't create table `ma_base`.`ma_table` (errno: 150 "Foreign key constraint is incorrectly formed")
Pour contourner ce problème on peut faire :
~~~
MariaDB [(none)]> SET FOREIGN_KEY_CHECKS=0;
Query OK, 0 rows affected (0.00 sec)
~~~
Ne pas oublier de remettre à "1" car sinon il y a risque de réduction de performances.
