[jQuery] Return Query Results From $.ajax POST


Is it possible to return Query results from a jquery $.ajax POST call?
It seems as though it will only return one value. What am I missing?
var formval = { preceptname:$(this) .val()};
$.ajax({
     type: "POST",
     url: "request_processor.cfm",
     dataType: "text",
     data: formval,
     success: function(response){
         $('#contentdiv').fadeIn(2000).html(response);
            }
        });
    });
