通过基于最大值的联接获取整行

Question

在mysql中，我有以下两个表：

**Seasons**
id
number
current

**Episodes**
id
number
season_id
other_info

我想从得到一个完整的排Episodes ，从加盟排Seasons都基于最大number两表的价值。

例如，如果我有第1、2、3季，我想从最近的第一个季中获取最新的剧集。

我从以下查询开始：

SELECT e.id as episode_id, s.id as season_id, MAX(s.number) AS season_number, MAX(e.number) AS episode_number, e.other_info
FROM (episodes AS e)
JOIN seasons AS s ON e.season_id=s.id
WHERE s.current =  1

可以，但是显示错误的other_info值。 我知道这是因为MAX()行进行了分组，但是其他值是随机的，因此我认为它只是从可用的第一行显示other_info 。

环顾四周，我发现了我认为可以解决的问题，但没有：

SELECT e.id as episode_id, s.id as season_id, MAX(s.number) AS season_number, MAX(e.number) AS episode_number, e.other_info
FROM (episodes AS e)
JOIN seasons AS s ON e.season_id=s.id
WHERE s.current =  1 AND
e.number = (select max(sube.number) from episodes sube);

在这种情况下，我只获取所有NULL值。

我认为这将帮助您：

SELECT seasons.*, episodes.* 
FROM episodes
INNER JOIN seasons ON episodes.season_id = seasons.id
ORDER BY seasons.number DESC ,episodes.number DESC 
limit 0,1
