while (Qrows.isValidRow()){
//Ti.App.questionsId = {questionsDesc:Qrows.fieldByName('Questions_Id')};
var questId = Qrows.fieldByName('table1_Id');
var questDesc = Qrows.fieldByName('table2_Desc');
//alert( Ti.App.questionsId.questionsDesc+"..."+Qrows.fieldByName('Questions_Id'));
Qrows.next();
}
//var l=0;
 var picker = Ti.UI.createPicker({
  top:'18%',
  //visibleItems:4,
  useSpinner: true
});
picker.selectionIndicator = true;   
self.add(picker);
 
var pickerValues = [];
 
var rows = db.execute('SELECT * FROM Table');
 
while (rows.isValidRow())
{
pickerValues=Ti.UI.createPickerRow({
    title:rows.fieldByName('table_Name'),
    id:rows.fieldByName('table_Id') 
});
picker.add(pickerValues);
rows.next();
}
picker.addEventListener('change',function(e){
     Ti.App.tableId = {tableDesc:e.row.id};
     infoBtn.title = 'info';

infoBtn.addEventListener('click',function(){
    var db = Titanium.Database.open('DB1'); 
var dbRows = db.execute('SELECT * FROM Table3 WHERE table_Id = "'+Ti.App.tableId.tableDesc+'" And table1_Id = "'+questId+'" ');
while (dbRows.isValidRow())
{
    var textField= Ti.UI.createWebView({

       // backgroundColor:'transparent',
        //backgroundImage:'../images/bg2.png'
    });
    self.add(textField);
dbRows.next();
}
 
db.close();
 
});
