Select *, perform generic query

I use the new cayenne 1.2M3, and I need run this query:

 

SELECT * FROM DBAORA.TT10COTIZACION, DBAORA.TT20MODELO

WHERE TT10NROCOT = 1

AND TT10NROCOT = TT20NROCOT

 

DataContext ctxt = BasicServletConfiguration.getDefaultContext(request.getSession());
String sql = "SELECT * FROM DBAORA.TT10COTIZACION, DBAORA.TT20MODELO " +                      " WHERE  TT10NROCOT = 1 AND TT10NROCOT = TT20NROCOT"; 
SQLTemplate query = new SQLTemplate(Vtvh010Clientes.class,sql,true); 
List data = null;    
try{
     data = ctxt.performQuery(query);
}catch(org.objectstyle.cayenne.CayenneRuntimeException e){

but don't return any rows, why???

the Vtvh010Clientes.class not corresponding with 2 tables for this query DBAORA.TT10COTIZACION, DBAORA.TT20MODELO, it is the problem??? how to resolve this problem, beucase i need all colunm the query.

 

In general, my problem is, How i can perform a generic query in the DataContext (SqlSelectQuery is deprecated) without any ObjEntity and DbEntity 

 

Any help would be much apreciatted. Thanks
