根据记录类型计算总和

Question

我被卡住了像图片这样的计算函数，我只能通过借方进行求和。

的歌手是他的系统

Saldo =如果位置1栏第2信用借记借记所以结果 - 信用，信用IF 1栏第2个积分，则结果为一信用 - 信用，信用IF第1栏第2借记卡，信用卡+借记这样的结果，等作为图片

这里是我的代码

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' 

Answer 1

这样的事情？

/* 
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
