Just to close this loop:

End up i am able to using code above to connect SQL/EXPRESS which is:

$dbh=DBI->connect("dbi:MTODBC:PC-NAME:Yield","<usr>","<pw>") || die "$
+DBI::errstr\n";

The problem i met is ODBC.ini setup incorrectly especially the port, we have to setup properly, but how?

here's some code to help:

1) tsql -LH <SERVER_NAME> => use this to get port and server name information.

   output: 
   ServerName ABC
   InstanceName SQLEXPRESS
    IsClustered No
        Version 12.0.xxxxxxx
            tcp xxxxx
             np \\ABC\pipe\MSSQL$SQLEXPRESS\sql\query

2) In SSMS (SQL query), type command like "select distinct local_net_address, local_tcp_port from sys.dm_exec_connections where local_net_address is not null"

this shows the port and local net address.

Thanks and Cheers!!!!! :)
