У меня есть таблица с именем tmp_emp_city с empid, recordcount и cityid.Я выбираю empid, recordcount и cityid из tmp_emp_city и извлекаю информацию о каждом сотруднике с помощью cityid и count из таблицы sulekhasmartmaster_v1.
Я сделал это с помощью курсоров,но это занимает так много времени (больше минуты).Как я могу сократить время?
