功能代码如下：

include ("conn/conn.php");

$sql = "select * from tb_user where id limit 5 "; //创建sql语句

$rst = $conn->execute ( $sql ) or die ( 'error： ' . $conn->errorMsg () ); //执行查询语句

$array = array ();

while ( ! $rst->EOF ) {

$array ['id'] = $rst->fields ['id']; # process $arr

$array ['user'] = iconv ( "utf-8", "gb2312", $rst->fields ['user'] ); # process $arr

$array ['pass'] = $rst->fields ['pass']; # process $arr

$array ['dates'] = $rst->fields ['dates']; # process $arr

if ($_GET ['insert'] == "导出") {

$sqls = "select * from tb_user where id=0 "; //创建sql语句

$ret = $con->execute ( $sqls ) or die ( 'error： ' . $con->errorMsg () ); //执行查询语句

$insert = $con->getInsertSQL ( $ret, $array ) or die ( 'update error：' . $con->errorMsg () ); //添加新数据

$con->execute ( $insert );

}

?>

<?php

echo $rst->fields ['id'];

?>

<?php

echo $rst->fields ['user'];

?>

<?php

echo $rst->fields ['dates'];

?>

$rst->movenext (); //指针下移

}

$rst->close (); //关闭连接

$conn->close ();

?>

-------------------

conn.php

include_once('../adodb5/adodb.inc.php'); //载入(include)adodb.inc.php文件

$conn = ADONewConnection('mysql');  //建立连接

$conn ->PConnect('localhost','root','111','db_database13'); //连接数据库

$conn -> execute('set names utf8');   //设置编码格式

$con = ADONewConnection("access");   //连接Access数据库

$con ->PConnect("Driver={Microsoft Access Driver (*.mdb)};Dbq=E:\\Program File\\phpdevlepe\\AppServ\\www\\practice\\13\\545\\conn\\data\\db_database13.mdb");

$con ->execute('set names gb2312');   //设置编码格式

?>

如果是sqlserver 则是：$conn-> PConnect("Driver={SQL Server};Server=localhost;Database=db_database13;",'sa','');这个格式
