sql - 将地理类型返回为 XML 的 SQL 查询

Question

我正在尝试从包含 Geography 类型的表中返回 XML。
SQL查询：

SELECT *
From Events
ORDER BY HydrantId ASC
FOR XML RAW ('Event'), ROOT ('Events'), ELEMENTS XSINIL;

我收到以下错误：

FOR XML does not support CLR types -   
cast CLR types explicitly into one of the supported types in FOR XML queries.  

如何将此地理专栏转换为可读的内容？
谢谢。

Answer 1

SELECT Column1, Column2, Column3, cast(GeographyColumn as varchar(max))
From Events
ORDER BY HydrantId ASC
FOR XML RAW ('Event'), ROOT ('Events'), ELEMENTS XSINIL;

中的值GeographyColumn将采用POINT (-77.010996 38.890358)格式。
