• Как обновить столбец максимальным значением?

    Гость в этой жизни.
    Вы столкнулись с ограничениями подзапросов команды dml (update);
    Вам нужно сначала посчитать максимальное значение через предварительный запрос, а уже после в виде переменной использовать это значение.

    Решение:
    @salt_quest = SELECT MAX(salt_quests) + 1 FROM repository_quests;
    UPDATE repository_quests SET status_game_quests = 1, status_progress_registration_quests = 0, salt_quests = @salt_quest
        WHERE status_accessibility_quests = 1 
            AND status_active_quests = 1 
            AND status_game_quests = 0 
            AND status_progress_registration_quests = 1 
            AND NOW() >= registration_date_quests;
