Código Delphi [-]
case RadioGroup1.ItemIndex of
  0:buscar:='Select codart,desart,pvpart,stkart From articulo.DB Where codart Like "' + (Edit1.text) + '%"';
  1:buscar:='Select codart,desart,pvpart,stkart From articulo.DB Where desart Like "' + (Edit1.text) + '%"';
  2:buscar:='Select codart,desart,pvpart,stkart From articulo.DB Where stkart <=10';
