Oracle-ösödik az SQL Server, gondolom ott már rég van ilyen.

Egy étteremkereső lekérdezés a fenti cikkből:

-Return Census Block regions with the count of restaurants
-contained in each region for each block group in the zipcode the user clicked on

DECLARE @clickedPoint dbo.Geometry;
SET @clickedPoint = dbo.Geometry::STPoint(@lat, @lon, 0);
SELECT c.id,
c.shape,
c.pop as [Population],
c.shape.STArea() as [Area],
(select count(*) from dbo.business b where c.shape.STIntersects(b.shape)=1
AND substring(sic,1,2)=’58′) as [Restaurant Count]
FROM dbo.census c, dbo.zipcodes z
WHERE c.shape.STIntersects(z.shape)=1 and z.shape.STIntersects(@clickedPoint)=1;
