问题描述
所以基本上我有两个表.第一张称为照片"的表格如下所示:
So basically I have two tables. First table called 'photos' looks like this:
id title
1 Some text here
2 Another text here
第二个名为"likes"的表如下所示:
and the second table called 'likes' looks like this
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
photos_id corresponds to id from 'photos' table
我正在使用以下查询进行全文布尔搜索,然后按相关性排序
I am using the following query to do fulltext boolean search and then sort by relevance
SELECT *, MATCH (title) AGAINST ('text' in boolean mode)
AS score FROM photos
WHERE MATCH (title) AGAINST ('text' in boolean mode) order by score desc;
按相关性排序很有效,但是现在我想按相关性相等时的喜欢总数进行排序...类似"按分数排序,total_likes desc ".有帮助吗?
Sorting by relevance is working well but now I want to sort also by total number of likes when the relevance is equal ... something like "order by score, total_likes desc". Any help?
推荐答案
您可以为此进行Left Join
并检查 SQLFiddle 此处.
You can do Left Join
for it and check SQLFiddle here.
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
