SQL Server无法识别多边形

Question

我从openstreetmap中提取了一堆区域的多边形坐标。令我惊讶的是，当我运行它时，它不会将其识别为多边形，而当我通过线串绘制它时，它会正确地绘制它。谁能告诉我为什么以及如何解决它？

我正在使用SQL Server 2016

select @poly as polygon, @linestring as linestring

Answer 1

如果你改变了 declare @poly geography和set @poly=geography::STPolyFromText... 至 declare @poly geometry和set @poly=geometry ::STPolyFromText...

您将在空间结果标签中看到多边形。
