Я работаю с существующей базой данных SQL 2005, которая не была реализована с отношениями FK между таблицами. Я попытался добавить отношения с диаграммой базы данных, и мое приложение сразу взорвалось, пытаясь редактировать или вставить любые данные, связанные с новым FK.
dbo.person [person_id | firstname | lastname | dateofbirth]
dbo.campaign [campaign_id | campaign_description]
dbo.disposition [disposition_id | disposition_description]
dbo.person_campaigns [person_campaign_id | person_id | campaign_id | disposition_id]
Таблица person_campaigns - это место, где человек, кампания и расположение связаны между собой. Не могли бы вы предоставить соответствующий синтаксис SQL для добавления правильных отношений FK между этими объектами?
