使用地理点 SQL Server 查找位于另一个内部的段

Question

让我解释一下附图Yellow line termed as Construction Planning identified by Planning Id and all other colors termed as Construction Segment identified by SegmentId。我正在尝试使用地理点的STDistance 函数通过传递PlanningID=25801 来查找SegmentId=12689 和SegmentId=12687。我的程序应该返回值12689 和12687，因为这两个值完全位于PlanningID=25801 中。但是，它应该排除值SegmentId=12688，因为该段不完全位于或该段的大部分不在施工规划内。 我在 SQL Server 中创建了以下脚本

declare    @Planningid INT
declare    @agencyID int
set @Planningid=25801
set @agencyID=79
DECLARE @finalresult int
DECLARE @result TABLE (id INT, starting sys.geography, ending sys.geography,
                          chachedroute sys.geography)
DECLARE @tablevar TABLE(id INT)
insert into @result select id,
starting,Ending,CachedRoute from Route R where AgencyId=@agencyID and LayerId=1 
                  and CachedRoute.STDistance((select CachedRoute from route 
                                               where id=@Planningid))<0.5
select * from @result
/* the above part of the code is working fine as it should */

/* the next part of the logic is not working and it is excluding all the Segment Id when it 
                                should not and should only exclude SegmentId=12688 */
insert into @tablevar
select id from @result where 
            chachedroute.STDistance((select starting from route where id=@Planningid))<700 
            and 
            chachedroute.STDistance((select ending from route where id=@Planningid))<700
intersect
select id from @result

select * from @tablevar

我猜这个问题是因为代码第二部分中的and 逻辑，它计算值是否在 700 米之内。这段代码最初是根据每个PlanningId 应该只有一个SegmentID 的概念创建的，这就是我通过匹配段的开始和结束来编码它的原因。但现在的修改是单个PlanningId 可以有多个SegmentID，我猜这就是问题所在。 任何有关如何修改代码的帮助将不胜感激。 表Route 包含以下属性：

1. ID（整数）
2. 起点（地理点）
3. 结局（地理点）
4. 缓存路线（地理点）
5. LayerId (int)
6. AgencyId(int)

值LayerId=1指的是Construction Segment，LayerId=4指的是Construction Planning

我已将上述函数更改为以下使其工作：

CREATE FUNCTION [dbo].[GetSegmentId]
(   
    @Planningid INT,
    @agencyID int
)

RETURNS @tablevar TABLE 
(
    id INT
)

AS

BEGIN
        declare    @CachedRoute geography
        DECLARE @finalresult int
        DECLARE @result TABLE (id INT, starting sys.geography, ending sys.geography,chachedroute sys.geography)
        

        set @CachedRoute = (select CachedRoute from route where id = @Planningid)

        insert into @result select id,
        starting,Ending,CachedRoute from Route R where AgencyId=@agencyID and LayerId=1 and CachedRoute.STDistance(@CachedRoute)<0.5 

        insert into @tablevar
        select id from @result where @CachedRoute.STDistance(starting)<700 and @CachedRoute.STDistance(ending)<700
        intersect
        select id from @result


    RETURN;
END;
