Hi,
 
Your %data% looks rather similar than the example. You seem to miss
"using unique", try what happens if you add it.

This is my Layer:

                SIZE 2
             END
        END
END # layer




My %data% is "geo_coordenada FROM (select cod_referencia as oid,
geo_coordenada, ind_cor from ponto_referencia where cod_referencia = 1 )
as map using SRID=4326"
The SQL brings me an geo info
("0101000020E610000079E9263108DC42C08716D9CEF75338C0") that in text is =
"POINT(-37.719 -24.328)"

Hi,

First add DEBUG 5, it may generate some interesting information for you
into ms_errorfile. Next, comment out maxscale to be sure it is not
preventing the rendering. Change it to MAXSCALEDENOM later, maxscale is
not to be used any more. Add PROJECTION into your LAYER for getting more
control on what is happening. And tell us the exact request you were
using. Very often a blank map without any errors means that Mapserver
does not find data from the requested map window, and very often it is
because of some misconfiguration or misunderstanding with projections.

What does "not working" mean? Steve

Hello
I'm trying to make an POINT in the map but it's not working

this is my Layer
layer
        name "ponto"
        connectiontype POSTGIS
        connection "dbname=xxxx user=xxxxx host=xxxxx port=xxxxx"
        data "geo_info from table"
        type point
        status on
        metadata
                tile_source "nocache"
        end
        maxscale 3000001
        class
                style
                        size 4
                        symbol "circulo"
                        color 0 0 0
                end
                style
                        size 1
                        symbol "circulo"
                        color 255 255 255
                end
        end
end


The SQL brings me an geo info
("0101000020E610000079E9263108DC42C08716D9CEF75338C0") that in text is =
"POINT(-37.719 -24.328)"


Any Ideas ?
