SQL Query將地理類型返回爲XML

Question

我試圖從包含地理類型的表中返回XML。
SQL查詢：

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

，我發現了以下錯誤：

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

我怎樣才能施放此地理列的東西是可讀？
謝謝。

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的值將是在POINT (-77.010996 38.890358)格式。
