когда я прохожу emplid, он работает, но когда я прохожу campus_id, это занимает бесконечное время

Question

Когда я передаю emplid, он запускается, но когда я передаю campus_id, он занимает бесконечное время

Если я скрою gg.campus_id и передам aa.emplid, он будет работать гладко в течение 3-4 секунд.

Вот подсказка, когда я даю идентификатор кампуса, это занимает бесконечное время

    GG.CAMPUS_id = : 1;
