числовая строка в mysql 5.7

Question

Mysql 5,7

Лог c выглядит следующим образом. Пользователь вводит ник, видит себя и + -5 пользователя

Код работает, если значения разные (1-я таблица), но если значения совпадают, данные теряют сортировку (2-я таблица) . Пожалуйста, помогите мне найти решение. Строки более 200 тыс. Строк в таблице

1-я таблица
