У меня есть запрос, который немного сложнее:
(SELECT category_id AS id, content_title AS title, content AS detail, 'content' AS type
FROM category_content
WHERE $where
ORDER BY id DESC)
UNION
(SELECT news_id AS id, news_title AS title, news_detail AS detail, 'news' AS type
FROM news
WHERE $where
ORDER BY id DESC)
Как я могу изменить этот запрос на Zend_Db_Select
объект?
