选择帖子内部联接类别slug

Question

╔═════════════╦════════════╗
║    posts    ║ categories ║
╠═════════════╬════════════╣
║ id          ║ id         ║
║ title       ║ name       ║
║ slug        ║ slug       ║
║ content     ║            ║
║ category_id ║            ║
╚═════════════╩════════════╝

鉴于某个类别的slug，我想选择该类别中的所有帖子。这些帖子与category_id - ＆gt;相关联id类别。

SELECT `posts.title` 
FROM `categories` 
INNER JOIN `posts` 
ON `posts`.`division` = "1"
WHERE `category_slug` = "$category_slug"

虽然给了我一个Unknown column 'posts.title' in 'field list'。如何根据类别的slug选择所有帖子？

Answer 1

看起来你想要

SELECT `posts`.`title`

而不是

SELECT `posts.title`

Answer 2

应该是

SELECT `posts`.`title`
