хранимая процедура mysql возвращает 0 затронутых строк

Question

Я пытаюсь запустить хранимую процедуру в mysql, и она возвращает 0 строк.человек выбирает работу отлично, и они также отлично работают как группа вместе.При совместном запуске они создают серию временных таблиц, а затем возвращают финальную таблицу в конце.Опять все работает нормально.Я посмотрел на другие вопросы и не вижу ошибки в моем запросе.
