根据给定条件计算剩余运行余额的 SQL 查询 [英] SQL Query to calculate remaining running balances based on a given conditions
问题描述
我有一个这样的股票交易表:
I have a stock transaction table like this:
StockID Item TransDate TranType BatchNo Qty Price
10001 ABC 01-Apr-2012 IN 71001000 200 750.0
10002 ABC 02-Apr-2012 OUT 100
10003 ABC 03-Apr-2012 IN 71001001 50 700.0
10004 ABC 04-Apr-2012 IN 71001002 75 800.0
10005 ABC 10-Apr-2012 OUT 125
10006 XYZ 05-Apr-2012 IN 71001003 150 350.0
10007 XYZ 05-Apr-2012 OUT 120
10008 XYZ 15-Apr-2012 OUT 10
10009 XYZ 20-Apr-2012 IN 71001004 90 340.0
10010 PQR 06-Apr-2012 IN 71001005 50 510.0
10011 PQR 15-Apr-2012 IN 71001006 60 505.0
10012 MNO 01-Apr-2012 IN 71001007 76 410.0
10013 MNO 11-Apr-2012 OUT 76
我的每笔 IN 交易都有与之相关的价格和批号(批号).现在我想通过先进先出(FIFO)规则来计算剩余数量，这意味着先进先出.调整数量后，将针对同一项目的每个 IN 交易计算剩余余额，如下所示:
Each of my IN transactions has price associated to it and a batch number (lot number). Now I would like to calculate the remaining quantity by First In First Out (FIFO) rule, meaning the first in should be adjusted with first out. After adjusting the quantities the remaining balances are to be calculated against each IN transaction for the same item as shown below:
StockID Item TransDate TranType BatchNo Qty Price RemainingQty
10001 ABC 01-Apr-2012 IN 71001000 200 750.0 0
10002 ABC 02-Apr-2012 OUT 100
10003 ABC 03-Apr-2012 IN 71001001 50 700.0 25
10004 ABC 04-Apr-2012 IN 71001002 75 800.0 75
10005 ABC 10-Apr-2012 OUT 125
10006 XYZ 05-Apr-2012 IN 71001003 150 350.0 20
10007 XYZ 05-Apr-2012 OUT 120
10008 XYZ 15-Apr-2012 OUT 10
10009 XYZ 20-Apr-2012 IN 71001004 90 340.0 90
10010 PQR 06-Apr-2012 IN 71001005 50 510.0 50
10011 PQR 15-Apr-2012 IN 71001006 60 505.0 60
10012 MNO 01-Apr-2012 IN 71001007 76 410.0 0
10013 MNO 11-Apr-2012 OUT 76
从上表 ABC 中我们可以看到，在使用 FIFO 将 (125 + 100) OUT 数量与 IN 数量 (100 + 50 + 75) 进行调整后，批次 71001000 的剩余数量为 0，71001001 为 25并且批次 71001002 为 75.从剩余数量可以得出该值.
As we can see from the above table for item ABC, after adjusting (125 + 100) OUT qty against the IN qty (100 + 50 + 75) using FIFO the quantity remaining for the batch 71001000 is 0, 71001001 is 25 and for batch 71001002 is 75. From the remaining quantity the value can be derived.
请帮助我使用任何方法(基于光标或 CTE 或 JOINS 等)来实现这一点在此先感谢您的帮助.
Please help me to achieve this using any of the methods (either cursor based or CTE or JOINS, etc) Thanks in advance for the help.
