Question

此存储过程具有来自两个不同表的3个函数。

如果表B中的行确实存在qty字段。
如果表B中不存在该行，请从表A中插入。
最后将表A和表B中的数量相加，并使用新的求和值更新表B数量字段。

我唯一的问题是存储过程对表B中的每一行求和，而不是正确的行或插入的新行。可以用一些方向来解决？提前谢谢。

为什么不将SET语句更改为InvTotalQtyOnOrder + = 1，如果您只想增加计数？

此外，WHERE子句是多余的，因为您的INNER JOIN使用相同的列标准，因此您已经限制为该数据子集。

编辑：在讨论问题后，我想我对你想要的结果有了更好的了解。尝试使用此更新语句而不是第3次更新时使用的更新语句，看看它是否符合您的要求

UPDATE [InventoryMaster_tbl]
    SET InvTotalQtyOnOrder += (SELECT SUM(POLineItemQty) FROM PurchaseOrderItems_tbl WHERE InvManPartNumber = PartManufPartNum)
FROM InventoryMaster_tbl

编辑2：将WHERE子句添加到UPDATE以仅更新采购订单临时表中包含制造部件号的记录，以便仅更新新的采购订单。

UPDATE [InventoryMaster_tbl]
    SET InvTotalQtyOnOrder += 
    (SELECT SUM(POLineItemQty) FROM PurchaseOrderItems_tbl WHERE InvManPartNumber = PartManufPartNum)
FROM InventoryMaster_tbl
WHERE InvManPartNumber IN (SELECT PartManufPartNum FROM PurchaseOrderTmp_tbl)

如何阻止此查询汇总所有行而不只是一行？
