Bug description

When running the cron command, an error occurs on line 47 of ./apps/dav/lib/CalDAV/Reminder/Backend.php

The query on line 46 performs a GROUP BY on a column that is a BLOB. Oracle does not allow GROUP BY clauses with columns of that type.
línea 46 ./apps/dav/lib/CalDAV/Reminder/Backend.php

           $query = $this->db->getQueryBuilder();
            $query->select(['cr.id', 'cr.calendar_id','cr.object_id','cr.is_recurring','cr.uid','cr.recurrence_id','cr.is_recurrence_exception','cr.event_hash','cr.alarm_hash','cr.type','cr.is_relative','cr.notification_date','cr.is_repeat_based','co.calendardata', 'c.displayname', 'c.principaluri'])
                    ->from('calendar_reminders', 'cr')
                    ->where($query->expr()->lte('cr.notification_date', $query->createNamedParameter($this->timeFactory->getTime())))
                    ->join('cr', 'calendarobjects', 'co', $query->expr()->eq('cr.object_id', 'co.id'))
                    ->join('cr', 'calendars', 'c', $query->expr()->eq('cr.calendar_id', 'c.id'))
                    ->groupBy('cr.event_hash', 'cr.notification_date', 'cr.type', 'cr.id', 'cr.calendar_id', 'cr.object_id', 'cr.is_recurring', 'cr.uid', 'cr.recurrence_id', 'cr.is_recurrence_exception', 'cr.alarm_hash', 'cr.is_relative', 'cr.is_repeat_based', 'co.calendardata', 'c.displayname', 'c.principaluri');
            $stmt = $query->executeQuery();

The solution would be to rewrite that query, perform a GROUP BY WITHOUT the calendar_objects table, and then perform a JOIN with that table.

Or simply removing the GROUP BY clause is the easiest option.

       $query = $this->db->getQueryBuilder();
        $query->select(['cr.id', 'cr.calendar_id','cr.object_id','cr.is_recurring','cr.uid','cr.recurrence_id','cr.is_recurrence_exception','cr.event_hash','cr.alarm_hash','cr.type','cr.is_relative','cr.notification_date','cr.is_repeat_based','co.calendardata', 'c.displayname', 'c.principaluri'])
                ->from('calendar_reminders', 'cr')
                ->where($query->expr()->lte('cr.notification_date', $query->createNamedParameter($this->timeFactory->getTime())))
                ->join('cr', 'calendarobjects', 'co', $query->expr()->eq('cr.object_id', 'co.id'))
                ->join('cr', 'calendars', 'c', $query->expr()->eq('cr.calendar_id', 'c.id'));
        $stmt = $query->executeQuery();

My tables don't contain much data (they're almost empty—it's a new installation), so I can't verify whether the SELECT results return unique rows.

By including cr.id (the table's primary key) in the GROUP BY clause—since it's a unique value per row—the GROUP BY clause shouldn't consolidate or remove any duplicate records.

Steps to reproduce
