Fetch is a method used in dialogs that is overwritten, if the user wants more control over the output

<xpp> public boolean fetch() {

   Query q;
   QueryRun qr;
   // Get query from the dialog 
   qr = new QueryRun(this);
   if ((qr.prompt()) && (element.prompt()))
       while (qr.Next())
           InventTable = qr.get(tablenum(InventTable));
           // Do something, e.g.:
           //    element.send(InventTable);
           //    element.executesection(sectionname);
       // User cancel
       return false;
   return true;

} </xpp>
