|ID|ItemID|Item|Prev Bal|Current Delivered|Current Consumed|Current Damaged|Balance| --------------------------------------------------------------------------------------
我以前曾问过如何在此论坛上汇总表,以某种方式我能够获得良好的结果,这要归功于该社区的帮助,但我最近遇到了如上所述的问题。
Select I.ID, I.Item,
(Select IFNULL(SUM( (SELECT Quantity FROM inventory WHERE DATE(ItemTransactionDate) < CURDATE() GROUP BY I.ItemID)),0) -
IFNULL((SELECT Quantity FROM inventory WHERE DATE(ItemTransactionDate) < CURDATE() GROUP BY I.ItemID),0) -
IFNULL((SELECT Quantity FROM consumeditemmonitoring WHERE DATE(TransactionDate) < CURDATE() GROUP BY I.ItemID),0) As NEWBALANCE From inventory INV
LEFT OUTER JOIN ( Select ItemID,IFNULL(SUM(Quantity),0) As Quantity from damagedinventory group by ItemID) DMG On INV.ItemID=DMG.ItemID
LEFT OUTER JOIN (Select ItemID,IFNULL(SUM(Quantity),0) As Quantity from consumeditemmonitoring group by ItemID) CSMD On INV.ItemID=CSMD.ItemID GROUP BY I.ItemID),
(SELECT SUM(Quantity) As CurrentDeliveries FROM inventory WHERE DATE(ItemTransactionDate) = CURDATE() GROUP BY I.ItemID),
IFNULL(D.Quantity,0) As damagedQTY,
IFNULL(C.Quantity,0) As ConsumedQTY,
IFNULL(SUM(I.Quantity),0) - IFNULL(D.Quantity,0) - IFNULL(C.Quantity,0) As NEWBALANCE From inventory I LEFT OUTER JOIN
(Select ItemID,IFNULL(SUM(Quantity),0) As Quantity from damagedinventory group by ItemID) D On I.ItemID=D.ItemID
LEFT OUTER JOIN (Select ItemID,IFNULL(SUM(Quantity),0) As Quantity from consumeditemmonitoring group by ItemID) C On I.ItemID=C.ItemID GROUP BY I.ItemID"
我是编程的新手,所以我对此确实没有足够的知识。任何帮助将不胜感激,谢谢。
答案 0 :(得分:0)
希望此方法可行,或者您可以对其进行调整。 我用了滞后功能。这将向您显示该列的上一个值(另请参见前导函数here)
SQL查询:
