明智地根据余额调整付款答案

【问题标题】：Adjusting payments against balances some id wise明智地根据余额调整付款

【问题描述】：

我在表格中有Store_IDs 的总付款，需要针对transactions_ids 为各自的store_ids 结算/调整付款。

可以按如下方式创建表：

--- CREATE STORE_PAYMENTS TABLE--- CONTAINS RECEIVABLE AGAINST RECEIPTS NOS FOR STROES-------
CREATE TABLE DBO.STORE_PAYMENTS
 (STORE_ID VARCHAR(10) NOT NULL,
 RECEIPT_NO VARCHAR(10) NOT NULL,
 RECEIVABLE INT NOT NULL,
 PAYMENT_ADJUSTED INT NOT NULL,
 BALANCE INT NOT NULL)
 GO

INSERT INTO DBO.STORE_PAYMENTS
(STORE_ID,RECEIPT_NO,RECEIVABLE,PAYMENT_ADJUSTED,BALANCE)
VALUES
('STR1',1,100,0,0),
('STR1',2,200,0,0),
('STR1',3,300,0,0),
('STR2',1,100,0,0),
('STR2',2,100,0,0),
('STR2',3,50,0,0),
('STR3',1,0,0,0),
('STR3',2,150,0,0),
('STR3',3,300,0,0)

---- CREATE STORE_BALANCE TABLE --- CONTAINS INFORMATION OF IN HAND PAYMENTS -----------------
CREATE TABLE DBO.STORE_BALANCE
 (STORE_ID VARCHAR(10) NOT NULL,
 PAYMENTS INT NOT NULL)
 GO

INSERT INTO DBO.STORE_BALANCE
(STORE_ID,PAYMENTS)
VALUES
('STR1',600),
('STR2',700),
('STR3',300)

SELECT * FROM DBO.STORE_BALANCE
SELECT * FROM DBO.STORE_PAYMENTS

调整支付的顺序可能是基于RECEIPT_NO order或rowid。

突出显示的列中的必需输出：

将示例数据共享为 DDL + DML 很棒，但您还应该解释所需输出的逻辑，并展示您已经尝试过的内容。
为什么 str2 在 250 的账单上支付了 700？
亲爱的 Zohar，我尝试在 SQL 中应用会计中使用的 FIFO 方法，但这对于这个问题来说太复杂了。
STR1,STR2... 是分配给不同商店的 ID，这些商店可能在特定时间点之前累积付款。付款可能少于未付总额，也可能多于未付金额（针对多张发票）。有时，我们需要根据未付发票/收据调整付款。我们必须根据可用付款关闭尽可能多的收据。
