簡單的資料庫鎖表操作

	public function locktable(){
    $sql="LOCK TABLES think_members WRITE";
    $re=M()->execute($sql);
    $sql1="select * from think_members where uid=1";
    $res=M()->query($sql1);
    $sql2="update think_members set password=56565 where uid=1";
    $upd=M()->execute($sql2);
    sleep(5);
    $sql3 = "UNLOCK TABLES"; 
    M()->execute($sql3); 
	}
	public function locktables(){
	   $re=M('think_members')->select();
	   dump($re);
