Access attributes for a non spatial table from mapViewer JavaScript API

Question

I have a non spatial table that contains bridge attributes that are identified by a unique bridge number. There is a spatial table containing the bridge location and bridge no. I have tried to add both tables as a JDBC theme but there is no attribute data:
var baseQuery="select b.obj, b.bridge_no, b.travel_direction_code, cway_code "+
", m.design_load_code DESIGN_LOAD "+
" from bridge b LEFT OUTER JOIN BRIDGE_MISCELLANEOUS m on b.id= m.bridge_id where b.road_no ='" + roadNo+"'";
var theme = '<themes><theme name="JDBC_THEME_BRIDGE" >' +
'<jdbc_query ' +
'datasource="wms" '+
'jdbc_srid="28355" ' +
'spatial_column="obj" '+
'asis="true" ' +
'render_style="M.BRIDGE_BW">' + baseQuery +
'</jdbc_query></theme></themes>' ;
bridgeTheme = new MVThemeBasedFOI('bridgeTheme1',theme);
This displays the bridges ok but there is no attribute data it seems like the query only returns the spatial object. Is there another way to access the attributes?

Answer 1

add the hidden_info tag to the theme def as in:
var theme = "<theme name='JDBC_THEME' fetch_size='200'>" +
"<jdbc_query spatial_column='geom' jdbc_srid='8307' " +
"render_style='m.star' datasource='mvdemo'>select geom, id, name from test_points" +
"<hidden_info>"+
" <field column=\"NAME\" name=\"My name\"/>"+
" <field column=\"ID\" />"+
"</hidden_info>"+
"</jdbc_query></theme>" ;
