我在 IF() 条件下执行 SUB SELECT 时遇到问题。

如果类型不等于某个值，我试图让它选择选择 MIN 保存时间，从计算中排除该值。

这是我当前的 SQL 查询，除了 IF() 之外有效：

SELECT
t.episode,
t.anime_id,
MAX(t.type) as type,
MIN(t.HD) as HD,
MAX(t.thumbnail) as thumbnail,
IF((MAX(t.type)!="raw"),(SELECT MIN(e.saved) FROM anime_episodes e WHERE e.type=MAX(t.type) AND t.episode=e.episode AND t.anime_id=e.anime_id GROUP BY e.anime_id, e.episode), (MIN(t.saved))) as time,
// UP HERE ^
MAX(t.filler) as filler,
m.anime_name,
m.furl,
m.video_thumb
FROM anime_episodes t
LEFT JOIN anime_list m ON
( t.anime_id=m.anime_id )
WHERE t.approved=1 AND t.locked=0 AND m.status=0 AND t.episode>=m.latest_ep
GROUP BY t.anime_id, t.episode
ORDER BY time DESC LIMIT 0,24

我的语法有什么问题吗？对我来说看起来不错，但错误是：

SQL error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE type!="raw")) as time, MAX(t.filler) as filler,m.anime_name, m.furl, m.vid' at line 1

编辑：正确答案，但我必须添加一些分组，因为它返回多个结果。谢谢！

您忘记添加from table语句

尝试这个：：

SELECT
t.episode,
t.anime_id,
MAX(t.type) as type,
MIN(t.HD) as HD,
MAX(t.thumbnail) as thumbnail,
IF((type="raw"),(MIN(t.saved)), (SELECT MIN(saved) from  anime_episodes WHERE type!="raw")) as time,
// UP HERE ^
MAX(t.filler) as filler,
m.anime_name,
m.furl,
m.video_thumb
FROM anime_episodes t
LEFT JOIN anime_list m ON
( t.anime_id=m.anime_id )
WHERE t.approved=1 AND t.locked=0 AND m.status=0 AND t.episode>=m.latest_ep
GROUP BY t.anime_id, t.episode
ORDER BY time DESC LIMIT 0,24
