Hi, I am dealing with some thematic map to be rendered with mapserver.
I am actually using mapserver data access connection methods ( http://mapserver.org/it/input/vector/postgis.html#data-access-connection-method ) to perform joins between geometry and attributes tables using mostly aggregate functions. I would like to use postgis views to put all the logic in the database but I am not sure I am doing it in the right way. I want to count the number of points in table A falling in each polygon in table B, thus obtaining a polygon table with an attribute. Here follows my view definition I would like to have feedback on: SELECT subquery.the_geom::geometry(MultiPolygon,32632) AS the_geom, count(s.count_att) FROM table1 A JOIN ( SELECT the_geom, gid FROM table2 B) subquery ON A.id = subquery.id GROUP BY subquery.the_geom; Regards /raffaele
