Hi Romain,
Assuming you have PostGIS installed and position is defined as a point or multpoint ADT then you could use the ST_Intersect operator
SELECT *
FROM map
WHERE ST_Intersects(position, 'MULTIPOINT(-1 -1,1 -1,1 1,-1 1)');

Hi, i'm trying to request a database using data type "point" using keyword "IN" with a list of point generated by PHP, like this:'SELECT * FROM map WHERE position IN ((point(-1,-1), (point(1,-1), point(1,1), point(-1,1))'
but this request returns me an error: operator doesn't exist point = point.
so i tried to use a path unstead of list of point like this:
'SELECT * FROM map WHERE position <@ path '(point(-1,-1), (point(1,-1), point(1,1), point(-1,1))'
but this request returns me the point 0,0???
Is anybody have a suggestions?
Thanks.
