根据相关性和一个领域进行排序
所以基本上我有两张桌子。 第一张名为“照片”的表格如下所示:
id title
1 Some text here
2 Another text here
而名为'likes'的第二张表看起来像这样
id photos_id user_id
1 1 10
2 1 11
3 2 12
photos_id对应于'照片'表中的ID
我正在使用以下查询来执行全文布尔搜索,然后按相关性进行排序
SELECT *, MATCH (title) AGAINST ('text' in boolean mode)
AS score FROM photos
WHERE MATCH (title) AGAINST ('text' in boolean mode) order by score desc;
根据相关性排序效果很好,但现在我想在相关性相同的情况下按喜欢的总数排序......例如“ 按分数排序,total_likes desc ”。 任何帮助?
你可以为它做Left Join
,并在这里检查SQLFiddle 。
SELECT
p.*,
MATCH (title) AGAINST ('text' IN BOOLEAN MODE) AS score ,
COUNT(li.id) AS total_likes
FROM photos p
LEFT JOIN likes li
ON p.id = li.photo_id
WHERE MATCH (p.title) AGAINST ('text' IN BOOLEAN MODE)
GROUP BY
li.photo_id
ORDER BY
score , total_likes DESC
