基于点位于给定多边形内将多边形表连接到点表时出错

Question

我试图实现的总体目标是基于一个表中的一个点（从以英尺为单位的 xy 坐标创建）将两个表连接在一起，该点落在另一个表的多边形内。预期的结果是记录和它所在的多边形的名称。执行查询时，返回以下错误，总结如下：

在执行用户定义的例程或聚合“几何”期间发生 .NET Framework 错误： System.FormatException: 24114: 输入熟知文本 (WKT) 中的标签 395 无效。

由于不熟悉 SQL 中的几何数据，我不确定自己是否走在正确的道路上，因此不胜感激。

我尝试加入的多边形表是一个临时表，多边形被格式化为几何图形。通过创建空间输出，单独运行以下代码会按预期执行。

抱歉，我的手机似乎无法进行代码格式化，并且我的工作计算机的浏览器不支持。

DECLARE @Hex1 TABLE    (PolyGeom geometry, Hex varchar(6))                 

INSERT INTO @Hex1

多边形表所连接的表没有点，因此创建了一个包含计算点字段的表。通过返回带有点的记录，单独运行以下代码可以按预期工作。

INSERT INTO #Points (Primary_Key, geom)
select a.rID, geometry::STGeomFromText('POINT('+convert(varchar(20),a.x_coordinate)+' '+convert(varchar(20),a.y_coordinate)+')',0) as geom
from data_a a'''

表格连接如下所示

 WITH CTE1 AS --Due the number of polygons exceeding insert limits, multiple tables are created and unioned in a CTE

  ( Select*
  From @Hex1

  UNION ALL
  Select*
  From @Hex2

   UNION ALL
  Select*
  From @Hex3

   UNION ALL
  Select*
  From @Hex4)

select a.rID, C.Hex
from data_a a --Existing table with x y coordinates

left join #points p  --Joins the point created in points table to the same case in go_data
on a.rID = p.Primary_key

left join CTE1 C   --Joins the hexagon to the point if hex containts the point
on p.geom.STIntersects (c.hex) =1'''

下面是完整的代码，每个表格中的多边形数量减少了

IF OBJECT_ID('tempdb..#Points') IS NOT NULL DROP TABLE #Points

create table #Points (Primary_key numeric identity not null,  geom  geometry)
SET IDENTITY_INSERT #Points ON


INSERT INTO #Points (Primary_Key, geom)
select g.rin, geometry::STGeomFromText('POINT('+convert(varchar(20),a.x_coordinate)+' '+convert(varchar(20),a.y_coordinate)+')',0) as geom
from data_a a

Answer 1

这不只是一个错字吗？您应该将点几何与多边形的几何相交，而不是十六进制列。

left join CTE1 C   --Joins the hexagon to the point if hex containts the point
on p.geom.STIntersects (c.PolyGeom) =1
