You could do that using OGR virtual layer; Wiki page is
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?VirtualSpatialData.

Set DSN in odbc connection; for exemple French,
then Ovf file look like this :
<OGRVRTDataSource>
    <OGRVRTLayer name="STATIONS">
        <SrcDataSource>ODBC:French,STATIONS</SrcDataSource>
     	<SrcLayer>STATIONS</SrcLayer>
    	<GeometryType>wkbPoint</GeometryType>
    	<LayerSRS></LayerSRS>
                 <GeometryField encoding="PointFromColumns"
x="X_LAMBERT_II_ET" y="Y_LAMBERT_II_ET"/>
 </OGRVRTLayer>
</OGRVRTDataSource>
where X_LAMBERT_II_ET is X coordinates and Y_LAMBERT_II_ET is Y.

Map file layer tag is :
LAYER
    NAME OVF
    TYPE POINT
    CONNECTIONTYPE OGR
    CONNECTION "french.ovf"
    DATA "STATIONS" # the name of the OGRVrtLayer
    STATUS DEFAULT
    PROJECTION
      "init=epsg:27582"
    END
  DUMP TRUE
	CLASS
    		TEMPLATE "ttt_query.html"
    		SYMBOL "circle"
    		SIZE 6
    		NAME "STATION_FR"
    		OUTLINECOLOR 239 16 16
	END
END

You could also use Mapscript.
