谷歌地图v3 OVER_QUERY_LIMIT-用PHP MYSQL进行地理编码

我在使用谷歌地图api v3时出现OVER_QUERY_LMIT错误。我想通过地理编码从数据库中添加标记。如果我在sql查询中使用limit，那么会显示标记，如果我将limit增加到大于10，那么它会显示错误。

<?php
mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('dbname') or die(mysql_error());    

$result = mysql_query("SELECT * FROM deal WHERE cityID=44 LIMIT 10") or die(mysql_error());
$count = 0;
echo mysql_num_rows($result);
$row = mysql_fetch_array($result);
