GROUP BY syntax Error - sql

Question

SELECT
SinifNo, OgrNo, Kalan, Ad, Soyad, MAX(VadeGunu)
FROM
(SELECT
o.SinifNo, a.OgrNo, o.Ad, o.Soyad, o.Sezon, o.SubeKod,
o.TCNo, o.AnneAd, o.AnneMobil, o.BabaAd, o.BabaMobil,
a.Tarih, a.Tutar, a.Odenen, a.Kalan,
DATEDIFF(DAY, a.Tarih, (getdate() + 1)) AS VadeGunu
FROM
TblTahPlan a
JOIN
TblOgrenci o ON a.OgrNo = o.OgrNo)
GROUP BY
SinifNo, OgrNo, Kalan, Ad, Soyad
It is my SQL query. But I'm getting this error:
Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword 'group'.
What can I do to solve this?

Answer 1

If you format your query, it becomes more easy to read and more easy to spot the mistake:
select SinifNo
, OgrNo
, Kalan
, Ad
, Soyad
, MAX(VadeGunu)
FROM (
SELECT o.SinifNo,a.OgrNo,o.Ad,o.Soyad,o.Sezon,o.SubeKod,o.TCNo,o.AnneAd,o.AnneMobil,o.BabaAd,o.BabaMobil,a.Tarih,a.Tutar,a.Odenen,a.Kalan
, DATEDIFF(DAY,a.Tarih,(getdate()+1)) as VadeGunu
FROM TblTahPlan AS a
JOIN TblOgrenci AS o
ON a.OgrNo=o.OgrNo
) AS T1
GROUP by SinifNo,OgrNo, Kalan,Ad,Soyad
You were missing an alias for your subquery, and a space before the group by. Why are you selecting all those attributes in your subquery? Why do you use a subquery at all? You could just as easily do:
SELECT o.SinifNo
, a.OgrNo
, a.Kalan
, o.Ad
, o.Soyad
, MAX(DATEDIFF(DAY,a.Tarih,(getdate()+1))) as VadeGunu
FROM TblTahPlan a
JOIN TblOgrenci o
ON a.OgrNo=o.OgrNo
GROUP by o.SinifNo
, a.OgrNo
, a.Kalan
, o.Ad
, o.Soyad

Answer 2

Change to the code
join TblOgrenci o on a.OgrNo=o.OgrNo) as tbl group by SinifNo,OgrNo,

Answer 3

Dont write code for yourself. Have proper alignment and formatting in place.
Change your query as below. You have to give alias to your inner query.
select
SinifNo,
OgrNo,
Kalan,
Ad,
Soyad,
max(VadeGunu)
from (select
o.SinifNo,
a.OgrNo,
o.Ad,
o.Soyad,
o.Sezon,
o.SubeKod,
o.TCNo,
o.AnneAd,
o.AnneMobil,
o.BabaAd,
o.BabaMobil,
a.Tarih,
a.Tutar,
a.Odenen,
a.Kalan,
DATEDIFF(DAY,a.Tarih,(getdate()+1)) as VadeGunu
from TblTahPlan a
join TblOgrenci o on a.OgrNo=o.OgrNo) as tblA
group by SinifNo, OgrNo, Kalan, Ad, Soyad

Answer 4

you can use this way
SELECT SinifNo,OgrNo, Kalan,Ad,Soyad, max(VadeGunu)
FROM
(SELECT o.SinifNo As SinifNo
, a.OgrNo As OgrNo
, o.Ad As Ad
, o.Soyad As Soyad
, o.Sezon As Sezon
, o.SubeKod As SubeKod
, o.TCNo As TCNo
, o.AnneAd As AnneAd
, o.AnneMobil As AnneMobil
, o.BabaAd As BabaAd
, o.BabaMobil As BabaMobil
, a.Tarih As Tarih
, a.Tutar As Tutar
, a.Odenen As Odenen
, a.Kalan As Kalan
, DATEDIFF(DAY,a.Tarih,(getdate()+1)) AS VadeGunu
FROM TblTahPlan a
Inner Join
TblOgrenci o
On a.OgrNo = o.OgrNo ) c
GROUP BY c.SinifNo
, c.OgrNo
, c.Kalan
, c.Ad
, c.Soyad
