どのように私は、行ごとの収支を計算し、すべての借方と貸方のためのバランスを取得したい

Question

以下のクエリを使用してすべての行に対してバランスを得ることができます。..

SELECT SUM(IF(s.AMT>0 AND s.SLE_CODE=11,s.AMT,0)) AS DEBIT, 
     SUM(IF(s.AMT<0 AND s.SLE_CODE=11,s.AMT,0)) * -1 AS CREDIT 
FROM 
    sldtl AS s 
LEFT JOIN 
    transtype 
ON 
    transtype.TransTypeID = s.TR_CODE 
WHERE 
    s.SL_BRCODE= 1 AND s.SL_CLIENTID= 267 AND s.SLC_CODE= 13 AND s.SLT_CODE= 15 AND 
    s.REF_NO= s.REF_NO AND s.TR_DATE >= (SELECT s.TR_DATE FROM sldtl AS s ORDER BY s.TR_DATE DESC LIMIT 1)-INTERVAL 6 MONTH 
GROUP BY 
    s.TR_DATE DESC, s.TR_CODE, s.TR_CTLNO 

必要な結果

+-----------+--------------+---------------+ 
| DEBIT | CREDIT | BALANCE | 
+-----------+--------------+---------------+ 
|  0.00 |  700.00 |  -700.00 | 
|  0.00 |  700.00 |  -1400.00 | 
| 400.00 |   0.00 |  -1000.00 | 
| 2000.00 |  500.00 |  500.00 | 
+-----------+--------------+---------------+ 

Answer 1

問題の簡略化されたバージョンを考えてみましょう：

debitとcreditの列のみを含む表。

balanceTable：

debit credit 
    0  700 
    0  700 
400   0 
2000  500 


SELECT 
debit, 
credit, 
@balance := @balance + debit - credit AS balance 
FROM balancetable, (SELECT @balance := 0) var; 

SQL FIDDLE DEMO

だからあなたの場合には、それはのようになります：追加@balanceについて

SELECT 
t.DEBIT, 
t.CREDIT, 
@balance := @balance + t.DEBIT - t.CREDIT AS BALANCE 
FROM 
(
    SELECT SUM(IF(s.AMT>0 AND s.SLE_CODE=11,s.AMT,0)) AS DEBIT, 
       SUM(IF(s.AMT<0 AND s.SLE_CODE=11,s.AMT,0)) * -1 AS CREDIT 
    FROM 
     sldtl AS s 
    LEFT JOIN 
     transtype 
    ON 
     transtype.TransTypeID = s.TR_CODE 
    WHERE 
     s.SL_BRCODE= 1 AND s.SL_CLIENTID= 267 AND s.SLC_CODE= 13 AND s.SLT_CODE= 15 AND 
     s.REF_NO= s.REF_NO AND s.TR_DATE >= (SELECT s.TR_DATE FROM sldtl AS s ORDER BY s.TR_DATE DESC LIMIT 1)-INTERVAL 6 MONTH 
    GROUP BY 
     s.TR_DATE DESC, s.TR_CODE, s.TR_CTLNO 
) AS t , (SELECT @balance := 0) var; 

Answer 2

何そして、あなたはbalance列を計算したいですあなたの選択の最後に：

SELECT @debit : = SUM(IF(s.AMT>0 AND s.SLE_CODE=11,s.AMT,0)) AS DEBIT, 
    @credit := SUM(IF(s.AMT<0 AND s.SLE_CODE=11,s.AMT,0)) * -1 AS CREDIT, 
    @balance := @balance - @credit + @debit As BALANCE 
FROM sldtl AS s 
LEFT JOIN transtype ON transtype.TransTypeID = s.TR_CODE 
JOIN (SELECT @balance := 0) AS tmp 
WHERE s.SL_BRCODE = 1 
AND s.SL_CLIENTID = 267 
AND s.SLC_CODE = 13 
AND s.SLT_CODE = 15 
AND s.REF_NO = s.REF_NO 
AND s.TR_DATE >= (
    SELECT s.TR_DATE 
    FROM sldtl AS s 
    ORDER BY s.TR_DATE DESC 
    LIMIT 1 
) - INTERVAL 6 MONTH 
GROUP BY s.TR_DATE DESC, s.TR_CODE, s.TR_CTLNO
