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
