AX - How use Query with enum in where condition

When you need use enum item in Query where condition, use queryValue() function:

ProdRouteTrans prodRouteTrans;
Query q; 
QueryBuildDataSource qDS; 
QueryBuildRange qRange;
QueryRun qRun;
...
while
  select * from vm_resources
  where
  vm_resources.resource_mask != "" &&
  vm_resources.active == NoYes::Yes
  {
    q = new Query();
    qDS = q.addDataSource( TableNum( ProdRouteTrans ) );

    /* where condition: Qty only */
    qRange = qDS.addRange( FieldNum( ProdRouteTrans, TransType ) );
    qRange.value( queryValue( ProdRouteTransType::Qty ) );

    qRun = new QueryRun( q );
    while ( qRun.next() )
    {
       /* get ProdRouteTrans data from query */
       prodRouteTrans = qRun.get( TableNum( ProdRouteTrans ) );
       ...
    }
  ...
}
