Hi Jukka,

This is the error in the debug file:


Warning: [MapServer Error]: msDrawMap(): Failed to draw layer named 'test'. in /xxx/xx/xx/xxx.php on line 992

Warning: [MapServer Error]: msPOSTGISLayerParseData(): Error parsing POSTGIS data variable. Must contain 'geometry_column from table_name' or 'geom from (subselect) as foo' (couldnt find ' from '). More help: Error with POSTGIS data variable. You specified '%data%'. Standard ways of specifiying are : (1) 'geometry_column from geometry_table' (2) 'geometry_column from (sub query) as foo using unique column name using SRID=srid#' Make sure you put in the 'using unique column name' and 'using SRID=#' clauses in. For more help, please see http://postgis.refractions.net/documentation/ Mappostgis.c - version of Jan 23/2004. in /var/www/html/dev/jmonestel/trunk/app/lib/mapaMapscriptF.class.php on line 992




This is my Layer:
LAYER
	NAME test
	TYPE POINT
	STATUS ON
	connectiontype POSTGIS
	connection "dbname=xxxx user=xxxxx host=xxxxx port=xxxxx"
	data "%data%"
	projection
		"proj=latlong"
		"ellps=WGS84"
		"datum=WGS84"
	end
	CLASS
    	     NAME "juan"
    	     STYLE
		SYMBOL 'juan2'
		COLOR 0 119 255
		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 ?
