Question

我希望查询此事务表中的所有事务数据并相应地对它们求和。表格中的数据如下：

Company   PO      Document No   Document Type  Amount  
001       PO-001    222           OR            2.2
001       PO-001    222           OR            3.3  
001       PO-001    444           OP            4.4
001       PO-001    444           OP            5.5
001       PO-002    555           OP            1.2
001       PO-002    666           OR            1.2

只要相同采购订单编号的总金额但不同的文件类型没有理货我应该将它们显示为以下输出：

Company   PO     Document_No  DocumentType_OR  Amount DocumentType_OP Amount_PO  
 001      PO-001    222           OR              5.5         OP         9.9

你有没有建议我该怎么做？非常感谢你。

使用Group by和Sum Amount

select Company,PO,"Document No","Document Type",sum(Amount) as Amount
from yourtable
Where PO = 'PO-001'
group by Company,PO,"Document No","Document Type"

更新：使用conditional Aggregate

SELECT Company,
       PO,
       Min([Document No]),
       Max(CASE WHEN "Document Type" = 'OR' THEN "Document Type" END) As Document_Type_OR,
       Sum(CASE WHEN "Document Type" = 'OR' THEN amount END) AS Amount_OR,
       Max(CASE WHEN "Document Type" = 'OP' THEN "Document Type" END) As Document_Type_OP,
       Sum(CASE WHEN "Document Type" = 'OP' THEN amount END) AS Amount_PO
FROM   Yourtable
WHERE  PO = 'PO-001'
GROUP  BY Company,PO
