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.

如何将此地理位置列转换为可读的内容？感谢。

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中的值将采用POINT (-77.010996 38.890358)格式。

SQL Query将Geography类型作为XML返回
