Question

我使用的是SQL Server 2005，我希望得到1张发票的总价值

当前输出：

Invoice     price    
-------------------
1234       2000    
1234       2500     
9012        3000       
3456        1000

但是我的选择字段（这是为了价格）已经很长了，而且我不知道如何在其上添加总和，

   RIGHT('000000000000'+ convert(varchar,cast(A.IVC_ForeignGrossAmt as decimal(9,2))),13) as IVC_ForeignGross,

预期输出应为：

Invoice     price   
-------------------
1234       4500        
1234       4500       
9012        3000       
3456        1000

Answer 1

使用相关子查询，如下所示：

SELECT
  Invoice,
  (SELECT SUM(t2.price)
   FROM table1 t2
   WHERE t1.invoice = t2.invoice) price           
FROM Table1 t1;

这会给你：

| INVOICE | PRICE |
-------------------
|    1234 |  4500 |
|    1234 |  4500 |
|    9012 |  3000 |
|    3456 |  1000 |

Answer 2

您可以将SUM-OVER与PARTITION BY Invoice一起使用（类似于Group By）：

SELECT
   Invoice, SUM(price) OVER (PARTITION BY Invoice) AS price   
FROM 
   dbo.Table

（但是，不确定问题的RIGHT('000000000000...部分）

Answer 3

你的意思是出局意图，

Invoice     price   
-------------------
1234       4500             
9012        3000       
3456        1000

您可以尝试

SELECT INVOICE.ID, SUM(PRICE) FROM INVOICE
GROUP BY INVOICE.ID

Answer 4

SELECT Invoice, SUM(price) FROM table1 GROUP BY Invoice;

Answer 5

根据发票上的SUM，您只需要GROUP BY的价格，并根据需要格式化价格。

SELECT A.Invoice, 
RIGHT('000000000000'+ convert(varchar,cast(SUM(A.IVC_ForeignGrossAmt)
as decimal(9,2))),13) as IVC_ForeignGross 
FROM yourTable A
GROUP BY Invoice;

SQL获取总值
