With MySQL v5.7+ you have to specifically set either a valid date or NULL otherwise you get SQL errors. In previous versions setting a date to "" implied NULL, this is no longer the case which causes nice SQL errors all over the place. This new RDCheckDateTime is an overloaded function that calls the respective isValid method of QDate/Time/DateTime and either returns the requested formatted string or returns NULL as a string. This can then be used as part of an INSERT/UPDATE without breaking the stricter NULL interpretation of MySQL v5.7+.
