我必须从2个表中获取有限表的数据我正在使用此查询,并面临一个错误This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery
SELECT S.* FROM softwares S
WHERE S.SoftId IN (
SELECT V.* FROM versions as V
WHERE V.SoftId = S.SoftId
ORDER BY DateAdded DESC LIMIT 1
) LIMIT 5
我必须从Softwars.SoftId=Versions.SoftId的版本和软件中选择所有列,并从表版本中选择最新版本。
谢谢
最佳答案
SELECT s.*,v.*
FROM softwares s LEFT JOIN versions v ON s.SoftId = v.SoftId
WHERE DateAdded IS NULL
OR DateAdded = (
SELECT MAX(DateAdded)
FROM versions v2
WHERE v2.SoftId = s.SoftId
)

关于php - 此版本的MySQL尚不支持'LIMIT&IN/ALL/ANY/SOME子查询,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/51938960/
