SQL运行减法
我的结果集如下:
Item ExpectedQty ReceivedQty Short
Item01 30 45 5
Item01 20 45 5
Item02 40 38 2
item03 50 90 10
item03 30 90 10
item03 20 90 10
查询是:
select a.Item, a.ExpectedQty,b.ReceivedQty, b.Short
from a join b on a.Item = b.Item
我需要获得第二个图表中的结果。基本上,我每行都有收到的总数量,我需要根据预期数量显示收到的数量,如果有任何短缺,我需要在最后一行显示。
预期:
Item ExpectedQty ReceivedQty Short
item01 30 30 0
item01 20 15 5
item02 40 38 2
item03 50 50 0
item03 30 30 0
item03 20 10 10
提前致谢。

-- Just a brief of business scenario is table has been created for a good receipt.
-- So here we have good expected line with PurchaseOrder(PO) in first few line.
-- And then we receive each expected line physically and that time these
-- quantity may be different
-- due to business case like quantity may damage and short quantity like that.
-- So we maintain a status for that eg: OK, Damage, also we have to calculate
-- short quantity
-- based on total of expected quantity of each item and total of received line.

SELECT ''as'ITEM', ''as'PO#', ''as'ExpectedQty',''as'ReceivedQty',
''as'DamageQty' ,''as'ShortQty' UNION ALL
SELECT 'ITEM01','PO-01','30','30','0' ,'0' UNION ALL
SELECT 'ITEM01','PO-02','20','15','5' ,'0' UNION ALL
SELECT 'ITEM02','PO-01','40','38','2' ,'0' UNION ALL

SELECT 'ITEM03','PO-02','30','30','0' ,'0' UNION ALL
SELECT 'ITEM03','PO-03','20','10','10','0' UNION ALL
SELECT 'ITEM04','PO-01','30','25','0' ,'5'
I have a result set as below:
Item ExpectedQty ReceivedQty Short
Item01 30 45 5
Item01 20 45 5
Item02 40 38 2
item03 50 90 10
item03 30 90 10
item03 20 90 10
query is:
select a.Item, a.ExpectedQty,b.ReceivedQty, b.Short
from a join b on a.Item = b.Item
I need to get result as in second chart. Basically I have a total of received quantity in each line and I need to show received quantity against Expected Quantity, if there is any shortage I need to show in last line.
Expected:
Item ExpectedQty ReceivedQty Short
item01 30 30 0
item01 20 15 5
item02 40 38 2
item03 50 50 0
item03 30 30 0
item03 20 10 10
Thanks in advance.

问题的一部分是获取预期项目数量的运行总计。为此,您需要一种方法来区分具有相同项目的行,以及卸载相同项目数量的顺序的规则。
为了尝试解决您的问题,我将假设有一个时间戳列,其值提供放电顺序并且在同一项目组中是唯一的。
这是我正在测试我的解决方案的示例数据定义:
这是我的解决方案:
One part of the problem is to get the running totals of expected item qunatities. For that you'd need a way to distinguish rows with same items from each other and a rule for the order of discharging same item quantities.
For the purpose of my attempt at solving your problem I'm going to assume there's a timestamp column whose values provide the order of discharge and are unique within same item groups.
Here's the sample data definition I was testing my solution on:
And here's my solution:
