returning only specific rows on a Mysql query
===

My application is a video game I'm writing and I'm trying to write a script to move my creatures around the map.
so I am trying to return unique spawn_id,posx,posy combinations (only 1 row per unique combination)  It doesn't matter which one is returned id is my key field.

    SELECT id,spawn_id,posx,posy,land,movelimit,next_turn FROM `game_moblist` WHERE 1 GROUP BY spawn_id,posx,posy

so given the data

    id spawn_id posx posy
    1  1        55   55
    2  1        55   55
    3  1        110  55

the query should return rows 1 and 3 (or 2 and 3 doesn't really matter) but not 1,2, and 3.
