sql-server - SQL Server : Specify Column Name as Attribute Using FOR XML

Question

我需要从 SQL Server 返回 XML 中包含空格的列别名。由于 XML 列名称中不能有空格，因此我想在“columnName”属性中返回此别名。一般来说，XML 需要如下所示:

<customers>
 <customer name="Shmo, Joe">
    <over50 columnName="Number of Orders Over 50 Pounds" value="10">
    <cancelled columnName="Orders Cancelled" value="2">
 </customer>
</customers>

表格如下:

|Name     |over50|cancelled
---------------------------
|Shmo, Joe|  10  |    2

如果可能的话，我真的很想使用“FOR XML”的 XML 提取方法。预先感谢您的任何见解。

Answer 1

这应该可以。

SELECT Name AS [@name],
       'Number of Orders Over 50 Pounds' AS [over50/@columnName],
       over50 AS [over50/@value],
       'Orders Cancelled' AS [cancelled/@columnName],
       cancelled AS [cancelled/@value]
FROM YourTable
FOR XML PATH('customer'), ROOT('customers')
