Comment (by Matthew Somerville): > So in this case play.name is functionally dependant on play.id (as it's the primary key of play) so if you're using a version of MySQL supported on Django 4.2 we'd definitely like to learn more about it as it's unexpected. So it turns out the database is MariaDB (11.1.2), not MySQL, and MariaDB does not appear to include/have the functional dependency requirement that this is based on. I don't know if you'd like me to raise that as a separate ticket, if Django is supposed to support both entirely equally, but yes, it looks like the code will not work at all with MariaDB with ONLY_FULL_GROUP_BY turned on. -- Ticket URL: <https://code.djangoproject.com/ticket/34978#comment:10> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
