我的结果如下:
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
我需要获得第二张图表中的结果。基本上我在每一行都有收到的数量,如果我需要在最后一行显示任何短缺,我需要显示收到的数量与预期数量。
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.

问题的一部分是获得预期项目状态的运行总计。为此,您需要一种方法来区分具有相同项目的行以及相同项目数量的排序规则。
为了尝试解决您的问题,我将假设有一个时间戳列,其值提供了放电顺序,并且在相同的项目组中是唯一的。
以下是我正在测试我的解决方案的示例数据定义:
CREATE TABLE TableA (Item varchar(50), ExpectedQty int, Timestamp int);
INSERT INTO TableA
SELECT 'Item01', 30, 1 UNION ALL
SELECT 'Item01', 20, 2 UNION ALL
SELECT 'Item02', 40, 1 UNION ALL
SELECT 'item03', 50, 1 UNION ALL
SELECT 'item03', 30, 2 UNION ALL
SELECT 'item03', 20, 3;
CREATE TABLE TableB (Item varchar(50), ReceivedQty int);
INSERT INTO TableB
SELECT 'Item01', 45 UNION ALL
SELECT 'Item02', 38 UNION ALL
SELECT 'item03', 90;
这是我的解决方案:
SELECT
Item,
ExpectedQty,
ReceivedQty = CASE
WHEN RemainderQty >= 0 THEN ExpectedQty
WHEN RemainderQty < -ExpectedQty THEN 0
ELSE RemainderQty + ExpectedQty
END,
Short = CASE
WHEN RemainderQty >= 0 THEN 0
WHEN RemainderQty < -ExpectedQty THEN ExpectedQty
ELSE ABS(RemainderQty)
END
FROM (
SELECT
a.Item,
a.ExpectedQty,
RemainderQty = b.ReceivedQty - a.RunningTotalQty
FROM (
SELECT
a.Item,
a.Timestamp,
a.ExpectedQty,
RunningTotalQty = SUM(a2.ExpectedQty)
FROM TableA a
INNER JOIN TableA a AS a2 ON a.Item = a2.Item AND a.Timestamp >= a2.Timestamp
GROUP BY
a.Item,
a.Timestamp,
a.ExpectedQty
) a
INNER JOIN TableB b ON a.Item = b.Item
) s
答案 2 :(得分:0)
SELECT a.ExpectedQty,
b.ReceivedQty,
CASE WHEN b.ReceivedQty < a.ExpectedQty
THEN b.ReceivedQty - a.ExpectedQty
ELSE 0
END Short
FROM dbo.a a
INNER JOIN dbo.b b
ON a.ItemId = b.ItemId
