SQL Query将地理类型返回为XML

Question

我试图从包含地理类型的表中返回XML。
SQL查询：

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

，我发现了以下错误：

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

我怎样才能施放此地理列的东西是可读？
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; 

在GeographyColumn的值将是在POINT (-77.010996 38.890358)格式。
