Hi, reading the thread "Difference between ST_Intersects and && operator "
If I understand exactly this mean that a query filter like this: select ... from table1 as a, table2 as b where ( (a.geom && b.geom) && (ST_Intersects(a.geom,b.geom)=true ) ) if faster than a query without the && like this: select ... from table1 as a, table2 as b where ( ST_Intersects(a.geom,b.geom)=true ) I understand correctly ? Thx, Andrea Peri. _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
