mysql - 有一个 mysql 查询，我希望能够从第二个表运行 order by

Question

SELECT * 
FROM app_detailsvvv as dtable 
WHERE primaryGenreName='".$ov['title']."'
  AND composed='1' AND 
  (SELECT COUNT(*) as c 
   FROM new_apps 
   WHERE trackId=dtable.trackId AND top>0) > 0 
ORDER BY top ASC

我在这里想要做的是ORDER BY表new_apps的顶部而不是app_detailsvvv，因为它甚至没有顶部字段，该怎么做？

Answer 1

为此使用INNER JOIN。这将是您的查询:

SELECT dtable.* FROM app_detailsvvv as dtable 
INNER JOIN new_apps ON new_apps.trackId=dtable.trackId
WHERE primaryGenreName='".$ov['title']."'
    AND composed='1' AND
    (SELECT COUNT(*) as c
    FROM new_apps
    WHERE trackId=dtable.trackId AND top>0) > 0
ORDER BY new_apps.top ASC
