Description: 

Before 9.1.0, in case of attempted INSERT of a record with an undefined column and no default value indicated in schema, MySql returned a 1364 error code, leading to a DatabaseExceptionWrapper being thrown instead of the more accurate IntegrityConstraintViolationException like the other drivers do.

As of 9.1.0, MySql also throws a IntegrityConstraintViolationException.
