比较MySql中的数据

Question

如果下一个条件没问题：（reserva.desde＆gt;＆＃39; 2015-07-03 23：59：59＆＃39;）或者（reserva.hasta＆lt;＆quot;＆quot;＆quot;＆quot;＆quot; 2015-07-02 00 ：00：00＆＃39）。显示全部。

如果后面条件是ko但是数据＆＃34; id_vehiculo＆＃34;与后面条件相同，我不想显示后面的数据。

我的现状查询：

package  {

    import flash.display.MovieClip;


    public class Main extends MovieClip {

        var list:List;
        public function Main() {
            butdin.addEventListener (MouseEvent.CLICK, sayit);
        }
        private function sayit (e:MouseEvent):void
        {


            list = new List();
            list.setSize (361,291);
            list.move (421, 254);
            //var i:uint;
            //for (i=1; i<8; i++)
            //{
            //list.addItem ( { label: "Track " + i } );
            //}
            list.addItem ( { label: "Track 1" } );//Opens swf file 1.swf in next frame on stage
            list.addItem ( { label: "Track 2" } );//Opens swf file 2.swf in next frame on stage
            list.addItem ( { label: "Track 3" } );
            list.addItem ( { label: "Track 4" } );
            list.addItem ( { label: "Track 5" } );
            list.addItem ( { label: "Track 6" } );
            list.addItem ( { label: "Track 7" } );

            addChild (list);
            list.addEventListener (Event.CHANGE, itemClick);


        }
        private  function itemClick ()
        {

            status_txt.text = "You selected: " + event.target.selectedItem.label;

        }
    }

}
