取消旋转具有多个（非规范化）值的多个重复列

Question

我有一个这样的多列表格...

+-------+----------------+---------+---------+-----------+------------+-----------+-----------+------------+---------+-----------+------------+
| Name  |     Email      | Address | Order1  | Shipping1 |   Date1    |  Order2   | Shipping2 |   Date2    | Order3  | Shipping3 |   Date3    |
+-------+----------------+---------+---------+-----------+------------+-----------+-----------+------------+---------+-----------+------------+
| John  | john@abcd.com  |     123 | Rock    |       123 | 02/11/2017 | Computer  |       123 | 07/11/2017 | Pen     |       123 | 12/11/2017 |

+-------+----------------+---------+---------+-----------+------------+-----------+-----------+------------+---------+-----------+------------+

我想在 T-SQL 中将列取消透视成这样的行...

+-------+----------------+---------+-----------+----------+------------+
| Name  |     Email      | Address |   Order   | Shipping |    Date    |
+-------+----------------+---------+-----------+----------+------------+

我用谷歌搜索并检查了与此相关的其他帖子，但无法获得三个值。 :(

感谢您的帮助！

Answer 1

您根本不需要在这里使用UNPIVOT。

您将能够将三个非规范化的订单 UNION 重新合并为扁平输出，如下所示：

SELECT name, Email, Address, Order1 AS Order, Shipping1 as Shipping, Date1 AS Date
FROM Table1
UNION ALL
SELECT name, Email, Address, Order2, Shipping2, Date2
FROM Table1
UNION ALL
SELECT name, Email, Address, Order3, Shipping3, Date3
FROM Table1
ORDER BY Name, Date;

（列名由UNION中的第一个select设置，ORDER应用于最终的UNIONed数据）
