常用的数据库链接方式

1.　用Asp链接access数据库
使用ODBC: 　
"dsn=baogao;uid=用户名;pwd=密码;"
使用OLE DB:　
"Driver={Microsoft Access Driver(*.mdb)};Dbq=/somepath/mydb.mdb;Uid=Admin;Pwd=password;"
2.　用Asp链接Sql Server 数据库
"Driver={SQL Server};Server=ServerName;Uid=xxxx;Pwd=xxxx;DataBase=DataBaseName"
3.　用php链接access数据库
<?
$dbc=new com("adodb.connection");
$dbc->open("driver=microsoft access driver (*.mdb);dbq=/path/db.mdb;Uid=Admin;Pwd=password;");
$rs=$dbc->execute("select * from tablename");
$i=0;
while (!$rs->eof){
$i+=1
$fld0=$rs->fields["UserName"];
$fld0=$rs->fields["Password"];
....
echo "$fld0->value $fld1->value ....";
$rs->movenext();
}
$rs->close();
?>
