php,while中使用mysql查询语句问题

Question

php的mysql查询语句可不可以这样用呢？$query = "SELECT name FROM bank WHERE area LIKE 'aaa'";$result = mysql_query($query) or die(mysql_error());while($row = mysql_fetch_array($result)) {    $http = $row['http'];    $task_query = "SELECT * FROM task WHERE link LIKE'%$http%'";    $task_result = mysql_query($task_query) or die(mysql_error());    while($task = mysql_fetch_array($task_result));            echo $task['high'].'<br />';    }
