如何在同一行中创建两个不同的值

Question

以下是我正在处理的数据集。

我正在尝试根据特定条件创建新列。下面是代码：-

SELECT
  *
,
CASE
WHEN [Partner Number] Like ('SAL%') THEN [Partner Name] 
ELSE ''
END AS [SAL Name],
    CASE
WHEN [Partner Number] Like ('SAL%') THEN [Partner Email Address] 
ELSE ''
END AS [SAL Email],
CASE
WHEN [Partner Number] Like ('CEO%') THEN [Partner Name] 
ELSE ''
END AS [CEO Name],
    CASE
WHEN [Partner Number] Like ('CEO%') THEN [Partner Email Address] 
ELSE ''
END AS [CEO Email],
    CASE
WHEN [Partner Number] Like ('VPS%') THEN [Partner Name] 
ELSE ''
END AS [VPS Name],
    CASE
WHEN [Partner Number] Like ('VPS%') THEN [Partner Email Address] 
ELSE ''
END AS [VPS Email]

     Into #Partner
  from (
         Select distinct  [Vendor Number],
[Purchasing Org],

[Partner Number],

[Partner Name]
, 
[Partner Email Address] from #Temp)k

但如果集合同时具有 SAL 和 CAL，它会生成两个不同的行。

可以在同一行生成它们，因为当我进行连接时，数据会爆炸。

理想情况下，Sal Name 和 cal Name 在同一行中。

我认为这更像是您应该在表示层中做的事情。

但是应该这样做：

WITH cte_cat
as
(
    SELECT *,   CASE    WHEN partnerNumber like 'CEO%' THEN 'CEO' 
                        WHEN partnerNumber like 'SAL%' THEN 'SAL'
                        ELSE 'OTHER' END as Category

    FROM #yourtable
),
cte_rn
as
(
    SELECT *,ROW_NUMBER () OVER (PARTITION BY vendorNbr,purchasingOrg,Category ORDER BY Commodity) as RN
    FROM cte_cat
)

SELECT oth.vendorNbr,oth.purchasingOrg,oth.commodity,oth.partnerNumber,oth.PartnerName,oth.ParterEmail,CEO.partnerNumber,CEO.PartnerName,CEO.ParterEmail,SAL.partnerNumber,SAL.PartnerName,SAL.ParterEmail
FROM cte_rn oth
LEFT JOIN cte_rn CEO
    ON CEO.Category = 'CEO'
    AND oth.RN = CEO.rn
    AND oth.vendorNbr=CEO.vendorNbr
    AND oth.purchasingOrg = CEO.purchasingOrg
LEFT JOIN cte_rn SAL
    ON SAL.Category = 'SAL'
    AND oth.RN = SAL.rn
    AND oth.vendorNbr=SAL.vendorNbr
    AND oth.purchasingOrg = SAL.purchasingOrg

WHERE oth.Category ='OTHER';
