Mapserver blank image

[Alejandro Rico]

Hi Raymond

looking at your mapfile, i found in the data source part in the layer, that
you aren't using an identifier in the select statement, and mapserver need
it, so add the column name that identify your geometries and use the clause
USING UNIQUE column_name.

May be this can help
