SQlite删除内连接

Question

我已经阅读了很多其他答案，但无法使其正常工作！

select * from invTypes
inner join invGroups on invtypes.groupID = invgroups.groupID
where invGroups.categoryID = 25;

如果类别ID匹配到25

，我只想删除invTypes中的记录

非常感谢帮助

我已经尝试过了：

delete from invTypes
inner join invGroups on invtypes.groupID = invgroups.groupID
where invGroups.categoryID = 25;

给出错误： “inner”附近：语法错误：

DELETE FROM invTypes
WHERE groupID in ( SELECT groupID FROM invGroups INNER JOIN invTypes ON (invGroups.groupID = invTypes.groupID) 
WHERE invGroups.categoryID = 25);

给出： 模糊列名：groupID：DELETE FROM invTypes WHERE groupID in（SELECT groupID FROM invGroups INNER JOIN invTypes ON（invGroups.categoryID = invTypes.categoryID）WHERE invGroups.categoryID = 25）;

Answer 1

您可以将delete与where子句

一起使用

delete from invTypes
where groupId in ( select groupId from invGroups where CategoryID =25)

Answer 2

DELETE invTypes
FROM invTypes
INNER JOIN invGroups
ON invTypes.groupID = invGroups.groupID
WHERE invGroups.categoryID = 25;
