I have a layer classification issue. I want to do something along the lines of
(semi-pseudocode ahead) --
$layerObj->{data} = 'the_geom FROM (SELECT gid, the_geom, class_name,
class_color FROM table) t USING UNIQUE gid';
$layerObj->{classitem} = 'class_name';
while (my $row in $layerObj->{data}) {
create class with 'name = class_name', 'expression = class_name',
'color = class_color'
}
How do I iterate over the rows retrieved from the table in order to create
classes? I don't see any obvious reference to a db result
set._______________________________________________
