mysql select查询
提问于 2011-07-17 01:34:35
我有两个表：interviews & interview_keywords。
面试有5个排序的关键字。我需要在排序列表的正确位置指定关键字的面试列表。这就是我到目前为止所得到的，它不起作用：
SELECT i.id,
i.title
FROM interviews AS i
LEFT JOIN interview_keywords AS ik ON i.id = ik.interview_id
WHERE i.cat_id = 1
AND ( (ik.keyword_id = 39 AND ik.sort = 1)
AND (ik.keyword_id = 33 AND ik.sort = 2)
AND (ik.keyword_id = 51 AND ik.sort = 3)
AND (ik.keyword_id = 96 AND ik.sort = 4)
AND (ik.keyword_id = 97 AND ik.sort = 5)) 回答 1
