getting rows from separate tables stacked in a single array ? (newbie, mysql)

Hi. This will probably sound simple to all of you but I am hitting my head on a brick wall so far :-). I need to generate a list (sorted by descending time) of different objects referenced in multiple tables. All those objects share a key related to a project. This works splendidly from a single table : $sql="select * from storyboards, where spot_id = \"$spot_id\" order by date_posted desc"; $result=MySQL_query($sql,$db); while($row=MySQL_fetch_array($result)) { $qt_title = $row["title"]; $qt_duration = $row["duration"]; $qt_date_posted = $row["date_posted"]; //(timestamp) $qt_description = $row["description"]; $qt_id = $row["quicktime_id"]; } Is there a mysql query that would allow me to stack complete rows in multiple tables at once (It seems more elegant because I can sort them while extracting them) or is there a way in PHP to concatenate results in a single array and then sort them by time... ? I tried to use a join query, wich produced an invalid query error. (I think it tries to produce a table with merged data, not just a stack of rows). $sql4="select * from quicktimes, other_images, storyboards, where quicktimes.spot_id, other_images.spot_id, storyboards.spot_id = \"$spot_id\" order by date_posted desc"; thank you for your help ! nicolas
