select a row that doesn't have a condition said - mysql

Question

I know the title doesn't make sense, I don't know how to reworded it.
So here's what I'm facing right now. I have one table, a big one, it has almost 2M rows. This is the table and it already filtered by NoRegis=1411940 and Jumlah>0
|| Kode || Nama || Kali || Hari || Resep || Jumlah ||
++======++======++======++======++=======++========++
||AL-128||SP 5 || || ||A ||5.00 ||
||AL-132||SP 10 || || ||A ||3.00 ||
||AL-132||SP 10 || || ||A ||7.00 ||
||DS-074||PARACE||3 ||1 ||R ||10.00 ||
||DS-119||ASP 81||1 ||1 ||R ||5.00 ||
||AL-242||VEN 2 || || ||A ||1.00 ||
||AL-242||VEN 2 || || ||R ||1.00 ||
I want a result that only consist of data that has Resep='R'. Something like this:
|| Kode || Nama || Kali || Hari || Resep || Jumlah ||
++======++======++======++======++=======++========++
||DS-074||PARACE||3 ||1 ||R ||10.00 ||
||DS-119||ASP 81||1 ||1 ||R ||5.00 ||
see, the last data (AL-242) has two rows consist of both Resep='R' and Resep='A', I tried something simple like
SELECT Kode,Nama,Kali,Hari,Resep,sum(Jumlah) FROM Frm_Ranap
where NoRegis=1411940 and Jumlah>0 and resep<>'A' GROUP by Kode
But I still got AL-242, which is not supposed to be there. I also tried something like
SELECT Kode,Nama,Kali,Hari,Resep,sum(Jumlah) FROM Frm_Ranap
WHERE kode not in (
select Kode FROM Frm_Ranap WHERE NoRegis=1411940 and Jumlah>0 and Resep='A')
and NoRegis=1411940 and Jumlah>0 GROUP by Kode
but every time I tried to run this query, it never show me any result and can't stop working, maybe because it has too much data.
Any sugestion?

Answer 1

Let's stick with the first query that returns. You just need to move the condition on A to a having clause instead of a where clause:
SELECT Kode, Nama, Kali, Hari, Resep, sum(Jumlah)
FROM Frm_Ranap
WHERE NoRegis = 1411940 and Jumlah > 0
GROUP by Kode
HAVING sum(resep = 'A') = 0;
The having expression counts the number of rows in each group (i.e. for each kode) that match the condition. The = 0 specifies that there are no such rows in the group.

Answer 2

You first select all rows that don't have what you want:
SELECT Kode FROM Frm_Ranap where resep<>'R' GROUP by Kode
Then you select the ones you want, but not the ones that are in the first select:
SELECT Kode,Nama,Kali,Hari,Resep,sum(Jumlah) FROM Frm_Ranap where NoRegis=1411940 and Jumlah>0 and Kode not in (SELECT Kode FROM Frm_Ranap where resep<>'R' GROUP by Kode) group by Jumlah

Answer 3

I Think this might help you
SELECT Kode,Nama,Kali,Hari,Resep,sum(Jumlah)
FROM Frm_Ranap
WHERE NoRegis=1411940
AND Jumlah>0
AND resep<>'A'
AND SUBSTRING(Kode, 1, 2) != 'AL'
GROUP by Kode
SUBSTRING(Kode, 1, 2) != 'AL' will filter the record which you want to eliminate

Answer 4

You can use not exists to select kode that doesn't have any Resep of type A. Generally, not exists is faster than not in when the subquery returns a large result set and the table is properly indexed.
select Kode,Nama,Kali,Hari,Resep,sum(Jumlah)
from Frm_Ranap t1
where NoRegis=1411940 and Jumlah>0 and Resep <> 'A'
and not exists (select 1 from Frm_Ranap t2
where t2.Kode = t1.Kode and t2.Resep = 'A'
and t2.NoRegis = 1411940 and t2.Jumlah > 0)
group by Kode
This query can take advantage of a composite index on (NoRegis,Kode,Resep,Jumlah)
