# Calculate sum as per record type

I am stuck with the calculation function like the picture, I can only do the summing by debit.

The singer is his system

Saldo = IF THE POSITION Column 1 Column 2 credit debit debit So the result - credit , credit IF Column 1 Column 2 credits , then the result is a credit - credit , credit IF Column 1 Column 2 debit , credit + debit So the result , and so on as the picture

here is my code

``````select
no,
tanggal,
O.debet,
(select sum(debet) from tbl_jurnal_umum where no <= O.no) 'Saldo'
from tbl_jurnal_umum O
where nama_perkiraan = 'kas'
``````

Something like this?

``````/*
DROP TABLE T;
CREATE TABLE T(NAME VARCHAR(3),ID INT, TRTYPE VARCHAR(1), AMOUNT INT);
INSERT INTO  T VALUES
('abc',1,'D','500'),('abc',1,'C','50'),('abc',1,'C','10'),('abc',1,'C','40'),
('abc',1,'D','500'),('abc',1,'C','100');
*/

SELECT S.NAME,S.ID,S.DEBIT,S.CREDIT,s.runtot runningtotal,
CASE WHEN S.DEBIT <> '' THEN S.RUNTOT ELSE '' END AS  DebitRunningTotal,
CASE WHEN S.DEBIT  = '' THEN S.RUNTOT ELSE '' END AS  CreditRunningTotal
from
(
SELECT T.NAME,T.ID,
CASE WHEN T.TRTYPE = 'D' THEN T.AMOUNT ELSE '' END AS DEBIT,
CASE WHEN T.TRTYPE = 'C' THEN T.AMOUNT ELSE '' END AS CREDIT,
@RUNTOT:=@RUNTOT + (
CASE WHEN TRTYPE = 'D' THEN AMOUNT
ELSE AMOUNT * -1
END )
AS RUNTOT
FROM   (SELECT @RUNTOT:=0) RT, T T
) s
