如何在Sql 2008中执行此空间查询？

i'm trying to do a spatial query in sql 2008 -> for a given list of POI's (point of interest, long/lat GEOGRAPHY data), which postcodes do they exist in (multipolygon GEOGRAPHY data).

我正在尝试在sql 2008中进行空间查询 - >对于给定的POI列表(兴趣点,长/纬度地理数据),它们存在于(多字形地理数据)中。

So this is the query i tried, but it's syntactically incorrect:-

所以这是我试过的查询,但它在语法上是不正确的: -

SELECT PostCodeId, ShapeFile
FROM Postcodes a
WHERE a.ShapeFile.STIntersects(
    SELECT PointOfInterest
    FROM PointOfInterests
    WHERE PointOfInterestId IN (SELECT Item from dbo.fnSplit(@PoiIdList, ','))

So this means i pass in a csv list of POI Id's and split them. That's not a problem .. it's my subquery in the STIntersects. That's invalid.

所以这意味着我传递了一个POI Id的csv列表并将它们分开。这不是问题..这是我在STIntersects中的子查询。那是无效的。

So .. any suggestions folks?

那么..有什么建议吗?

How about:

SELECT a.PostCodeId, a.ShapeFile
FROM (SELECT Item from dbo.fnSplit(@PoiIdList, ',')) AS POI_IDs
INNER JOIN PointOfInterests
    ON PointOfInterests.PointOfInterestId = POI_IDs.Item
INNER JOIN Postcodes a
    ON a.ShapeFile.STIntersects(PointOfInterests.PointOfInterest) = 1
