[postgis-users] ST_DWithin with radius 0.000001

[nguyen liem]

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?


Cheers.
