SQlite 删除内连接

Question

我已经阅读了很多其他答案，但无法正常工作！

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

如果类别 ID 与 25 匹配，我只想从 invTypes 中删除记录

非常感谢帮助

我已经试过了：

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

报错：在 "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：不明确的列名称：groupID：从 invTypes 中删除 WHERE groupID in ( SELECT groupID FROM invGroups INNER JOIN invTypes ON (invGroups.categoryID = invTypes.categoryID) WHERE invGroups.categoryID = 25);

Answer 1

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

Answer 2

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)
