Question

我想从表格中提取超过1万个代码，并在单独的列中显示欧元和英镑的售价。我的代码重复了每个代码，并在1万列中返回了两种货币，这些行超过2万行。

我不是高级技术人员：-（我正试图找到一种更好的做事方法。我浏览了一些不太复杂的示例，并提出了PIVOT或Dynamic Table函数，但我不明白如何在其中实现我的代码，因此我可以联系到你们。我知道您可以闭着眼睛做到这一点。

SQL代码

SELECT
    SI.Code AS [Item Code], SI.Name AS [Item Name], 
PLSA.SupplierAccountNumber AS [Supplier Code], SC.Symbol AS [Currency], 
SIS.ListPrice AS [€ Selling Price], PG.Code AS [PG Code]
    , PG.Description AS [PG Name], SIP.Price AS [Standard Cost]
    , CASE WHEN PB.PriceBandID = 129519 THEN '£ Standard'
    WHEN PB.PriceBandID = 1001 THEN '€ Standard'
    ELSE 'UNKNOWN' END AS [Selling Currency Std] 
    , SIS.SupplierStockCode AS [Supplier Stock Code], 
SIStatus.StockItemStatusName [Stock Code Status], SI.AnalysisCode8 AS 
 [Core / Non-Core]
    , SI.AnalysisCode7 AS [Product Chart], SI.AnalysisCode6 AS [Website Product]
FROM StockItem SI
    INNER JOIN StockItemSupplier SIS ON SIS.ItemID = SI.ItemID
    INNER JOIN PLSupplierAccount PLSA ON SIS.SupplierID = 
PLSA.PLSupplierAccountID
    INNER JOIN SYSCurrency SC ON PLSA.SYSCurrencyID = SC.SYSCurrencyID
    INNER JOIN ProductGroup PG ON PG.ProductGroupID = SI.ProductGroupID
    INNER JOIN StockItemPrice SIP ON SIP.ItemID = SI.ItemID
    INNER JOIN PriceBand PB ON PB.PriceBandID = SIP.PriceBandID
    INNER JOIN StockItemStatus SIStatus ON SIStatus.StockItemStatusID = 
SI.StockItemStatusID

结果是

| Item Code |...   |Selling Currency Std|
----------------------------
|        M1 |      |     €1.00 |
|        M1 |      |     £0.90 |
|        M2 |      |     €5.00 |
|        M2 |      |     £4.50 |
|        M3 |      |     €9.99 |

我想要的是什么

| Item Code |...   |Selling Currency Std €|Selling Currency Std £|
------------------------------------------------------------------
|        M1 |      |                €1.00 |                 £0.90|
|        M2 |      |                €5.00 |                 £4.50|
|        M3 |      |                €9.99 |                 £8.99|

我建议您使用类似excel的sumif之类的东西，仅在条件为true时才求和。如果（项目，货币）没有重复项，则总和将只增加2个值，一个始终为0，另一个为特定货币的实际SalesPrice。

; with ItemPriceList as
    (select
        SI.Code as [Item Code]
        , sum(iif(PB.PriceBandID = 1001, SIP.Price, 0)) as [Selling Currency Std €]
        , sum(iif(PB.PriceBandID = 129519, SIP.Price, 0)) as [Selling Currency Std £]
    from
        StockItem SI
        inner join StockItemPrice SIP on SIP.ItemID = SI.ItemID
            inner join PriceBand PB on PB.PriceBandID = SIP.PriceBandID
    group by
        SI.Code
    )
select
    IPL.[Item Code]
    , IPL.[Selling Currency Std €]
    , IPL.[Selling Currency Std £]
from
    ItemPriceList IPL
    --inner join the additional data for analysis

哦，不要再加上[供应商代码]，[PG代码]等附加信息，在您收集销售价格时，以后可以添加它们，这就是我使用CTE的原因

SQL在单独的列中返回重复行的对应值
