Ссылка на SQL-файл
Для каждого ID надо найти такие соответствующие ID, в которых три из четырех чисел совпадали бы. Проблема в том, что числа могут быть в разных столбцах.
И еще сложность, что каждому ID может соответствовать максимум 4, но может и 3 и 2 ID, и крайний случай - возможное единичное соответствие, которое тоже хотелось бы отследить.
Таким образом, желательно иметь на выходе таблицу вида
IDFR1FR2FR3FR4IDIDIDIDIDIDIDIDIDIDIDIDIDID
описывающую каждый ID исходной таблицы и его взаимоотношения с другими ID.
Спасибо!
