Hi all At the first time i used ST_Contains but it take a long time, so I used ST_Dwithin to improve the performance for the query statement but i don't know it is correct or not. I would like to know my points are within in polygon or not:
SELECT id, geom FROM my_neighbour WHERE ST_Dwithin (geom, *geometry*, *0.00001*) *geometry:* is a polygon(input parameter). *0.00001:* I means the radius of *geometry* is 1 meters, is it right?
