左除く、私は2つのSQLクエリを持って

Question

を動作していない参加します。

Select * from users (Returns 74 rows) 

id  firstname  lastname 
1  vignesh   km 
2  hariram   v 
3  vijesh   g 
. 
. 
74  ram    k 


Select * from details where time between '2017-05-11 00:00:00' AND '2017-05-11 23:59:59' (Returns 5 row). 


id  userid  logindate 
57  1   2017-05-11 09:07:23 
63  3   2017-05-11 09:04:57 
65  6   2017-05-11 09:14:45 
83  13   2017-05-11 09:26:43 
65  74   2017-05-11 09:11:53 

私は両方が動作していない

SELECT * 
FROM details dt LEFT JOIN users us ON us.id = dt.userid 
WHERE dt.logindate BETWEEN '2017-05-11 00:00:00' AND '2017-05-11 23:59:59' OR dt.userid IS NULL 
GROUP BY dt.userid; (6 rows returning - in that one row contains full of null) 

と

SELECT * 
FROM details dt LEFT JOIN users us ON us.id = dt.userid 
WHERE dt.logindate BETWEEN '2017-05-11 00:00:00' AND '2017-05-11 23:59:59' 
GROUP BY dt.userid; (5 rows returning) 


id  userid  logindate    firstname  lastname 
57  1   2017-05-11 09:07:23  vignesh   km 
63  3   2017-05-11 09:04:57  vijesh   g 
65  6   2017-05-11 09:14:45  ..    .. 
83  13   2017-05-11 09:26:43  ..    .. 
65  74   2017-05-11 09:11:53  ram    k 

を試してみました。しかし、私は最初のクエリ結果で利用可能で、2番目のクエリ結果では利用できない69行が必要です。

Answer 1

、GROUP BYを使用しないでください：

select * 
from users u 
left join details d on u.id = d.userid 
and d.logindate BETWEEN '2017-05-11 00:00:00' AND '2017-05-11 23:59:59' 
where d.id is null 

または使用not exists

select * 
from users u 
where not exists (
    select 1 
    from details d 
    where u.id = d.userid 
    and d.logindate BETWEEN '2017-05-11 00:00:00' AND '2017-05-11 23:59:59' 
) 

Answer 2

Select * from users us 
left join details dt on us.id=dt.userid 
WHERE dt.logindate NOT BETWEEN '2017-04-26 00:00:00' AND 
'2017-04-26 23:59:59' GROUP BY dt.userid 

Answer 3

あなたがgroup byを使用している理由を私は知りませんが、あなたがdetailsに存在しませusersレコードを取得したい場合、あなたはこれを試すことができ

SELECT * FROM details dt 
LEFT JOIN users us ON us.id = dt.userid 
WHERE dt.userid IS NOT NULL AND dt.logindate 
BETWEEN '2017-05-11 00:00:00' AND '2017-05-11 23:59:59
