如何转置以使各列具有不同的值，每列具有多行

Question

我有一个表格，每一行都有一个客户名称和一个GUID，该GUID是针对受众的代码。 我想要一个结果，每个列都有每个客户的GUID。

原始表格：

Customer        | Audience
                |
Customer A      | a4e7c9b7-c9d6-4698-8dc8-e0f2920f6bb7
Customer B      | 7a1d31b9-ecec-4c09-9eb9-cb10a8cc7d58
Customer A      | fa89f93d-ad7c-47ee-9a0c-598430c63c43
Customer C      | 0bc45f14-6c1b-48cf-a79e-a7cdc24deecc
Customer A      | 980b90cc-c923-46be-a180-bbbdf43169b2
Customer B      | 29d4806f-70fb-4b5f-9630-7314c32a536a

我需要一些东西，例如“选择客户A，客户B，客户C ........来自表的受众群体”

我需要的结果是这样的：

它可以将所有内容导出并在其中表现出色并进行操作。

谢谢！

一种选择是使用ROW_NUMBER为每个客户为每个GUID分配任意职位的数据透视查询。 我们可以通过三个独立的CTE来完成此操作，对于您数据集中的三个客户，每个CTE：

WITH cteA AS (
    SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) rn
    FROM yourTable
    WHERE Customer = 'Customer A'
),
cteB AS (
    SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) rn
    FROM yourTable
    WHERE Customer = 'Customer B'
),
cteC AS (
    SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) rn
    FROM yourTable
    WHERE Customer = 'Customer C'
)

SELECT
    a.Audience,
    b.Audience,
    c.Audience
FROM cteA a
FULL OUTER JOIN cteB b
    ON a.rn = b.rn
FULL OUTER JOIN cteC c
    ON a.rn = c.rn AND b.rn = c.rn;
