Chandra,

Are you connecting through a script or through the command line?

What's the code you're using to connect?

When i connect through command prompt the system works fine.
When i connecting mysql thro' PHP i am gettin g following error

Warning: Access denied for user: 'root@localhost' (Using password: NO) in c:\apache\htdocs\order\ClsOP_Connection.inc on line 20

Warning: MySQL Connection Failed: Access denied for user: 'root@localhost' (Using password: NO) in c:\apache\htdocs\order\ClsOP_Connection.inc on line 20
Could not connect

code is

<?
include("ClsOP_Connection.inc");

$ObjConnection = new OP_Connection("localhost","root","root","Orderprocessing");

$ObjConnection->Open();
?>

//ClsOP_Connection.inc----included file
<?
include("ClsOP_Connection.inc");

$ObjConnection = new OP_Connection("localhost","root","root","Orderprocessing");

$ObjConnection->Open();
?>


//ClsOP_Connction.inc
<?
class OP_Connection
{
var $StrHost;
var $StrUserid;
var $StrPassword;
var $StrDatabase;
var $StrLink;

Function OP_Connection($THost, $TUserid, $TPwd, $TDatabase)
{
$this->StrHost = $THost;
$this->StrUserid = $TUserid;
$this->StrPassword = $TPwd;
$this->StrDatabase = $TDatabase;
}

Function Open()
{
$this->Strlink = mysql_connect($this->Strhost, $this->StrUserid, $this->Password)
or die ("Could not connect");
mysql_select_db($this->StrDatabase)
or die ("Invalid Data base");
}

Function Close()
{
mysql_close();
}

}

?>

Function Open()
{
$this->Strlink = mysql_connect($this->Strhost, $this->StrUserid,

$this->Password

Should this be - $this->StrPassword
