关于php访问access的困惑,困扰了一天也没解决

<br />
$connstr="DRIVER=Microsoft Access Driver (*.mdb);DBQ=".realpath("D:/zhxlweb/web/www.test.com/zhxl.mdb") ; <br />
    $connid=odbc_connect($connstr,"","",SQL_CUR_USE_ODBC ); <br />
	<br />
	$sql = "select * from zhxl_article";<br />
	<br />
	$query = odbc_exec($connid,$sql);<br />
	<br />
	while($row=odbc_fetch_array($query)){<br />
		print_r($row);<br />
	}<br />
Copy after login


这样每次都可以把$row打印出来,我想返回结果只包含一个指定字段:
把 这句 $sql = "select * from zhxl_article"; 换成 $sql = "select article_title from zhxl_article";这样就什么也打印不出来,获取不到任何数据,我的字段都是正确的,只能返回(*),其余的都不行
