将地理类型作为 XML 返回的 SQL 查询

Question

我正在尝试从包含 Geography 类型的表中返回一个 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.  

我如何将这个 Geography 列转换为可读的内容？
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;

GeographyColumn 中的值将在 POINT (-77.010996 38.890358)格式。
