Я написав SP для цього, який повертає результати пошуку у вигляді назви таблиці, стовпчиків, в яких знайдено рядок ключового слова пошуку, а також шукає відповідні рядки, як показано на знімку екрана нижче.
Це може бути не найефективнішим рішенням, але ви завжди можете змінювати та використовувати його відповідно до своїх потреб.
