PHP + Mysql左边加入和喜欢

Question

我希望左连接到其他表格并且喜欢

  

我的代码：

    SELECT * 
    FROM `offer` 
    LEFT JOIN `category` ON (category.id=offer.brand OR category.id=offer.model) 
    WHERE offer.active='1' AND `finish`='0' AND 
         (category.title LIKE '%2013%' OR category.title_en LIKE '%2013%' OR
          offer.year LIKE '%2013%') 
GROUP BY offer.id 
ORDER BY `last_update` DESC LIMIT 0, 10

  

优惠表：

id     year     brand      model
------------------------------------
1      1390     1          2
2      2050     2          3
3      2010     1          4
4      2200     4          1

2      optima    optima_url
3      name      name_url
