我正在尝试使用连接创建一个选择查询
select distinct code from view req
inner join assoview assreq ON assreq.id_2 = req.id
where req.type_name = 'REQUEST' order by code
仅返回具有
之类关联的代码ABC003
ABC005
但是当我做左联时
select distinct code from view req
left join assoview assreq ON assreq.id_2 = req.id
where req.type_name = 'REQUEST' order by code
我得到了结果
ABC001
ABC002
ABC003
ABC004
ABC005
但我正在寻找如何获得没有像
这样的关联的代码ABC001
ABC002
ABC004

和<service>：
left join您也可以使用where . . . is null或select distinct code
from view req left join
assoview assreq
on assreq.id_2 = req.id
where req.type_name = 'REQUEST' and
assreq.id_2 is null
order by code;
，但这符合您当前的逻辑。

只需在IS NULL表
LEFT JOIN”即可
SELECT DISTINCT code
FROM view req
LEFT JOIN assoview assreq
ON assreq.id_2 = req.id
WHERE req.type_name = 'REQUEST'
AND assreq.id_2 IS NULL
ORDER BY code
答案 3 :(得分：0)
select distinct code from view req
inner join assoview assreq ON assreq.id_2 <> req.id
where req.type_name = 'REQUEST' order by code
