ACCESS数据库向MySQL快速迁移小程序(一)

为此我只好花了点时间写了两个小程序，用于将ACCESS数据库的内容向MySQL迁移，经使用，效果还不错，特在此写出奉献给各位一试或评判。
先概述一下使用方法，
1，将ACCESS的数据库建立一个"system DSN";
2，根据ACCESS数据库中各表的名称，在MySQL中建立相应的各个空表；
3，运行fdlist.php;
4，运行import.php;
5，每运行一次3，4步可迁移一个表，然后修改fdlist.php中的ACCESS源表名和MySQL中的目标表名，再运行3，4步，直至迁移所有的表，

以下为 fdlist.php源程序

or die("<p style='font-size:9pt;font-family:verdana;color:#803333;font-weight:bold'>No Database,</p>") ;
$odbc_table = "youroriginaltable" ; // The original table name in your ODBC database
$mysql_table = "yournewtable" ; // The new table name in your Mysql Database.

$recordsid = odbc_exec($conn, $odbc_query);
$idcounts = odbc_num_fields( $recordsid ) ;
$fdlist1 = "" ;
for ( $i = 1 ; $i <= $idcounts ; $i ++)
$fdlist1 .= odbc_field_name($recordsid,$i)."," ;

$fdlist1 = substr($fdlist1,0,strlen($fdlist1)-1) ;
