dear monks, i have to write a program, that takes database name, new user name and password as input from the user and create the database. I have written the following program.

use DBI;

    $drh = DBI->install_driver("mysql");
    $database ='testg1';
    $host ="localhost";
    $user = "root";
    $password = "passowrd";

    $rc = $drh->func('createdb', $database, $host, $user, $password, '
+admin');
    if ($rc == 1){print"new database created.."; }
            else{print "could not create database: $DBI::errstr\n";}

Though i am able to make the new database, i am not able to use it to create new user and grant rights. I am getting the following error.

DBI->connect(testg1:164.xxx.x.xxx:yyyy) failed: Access denied for user
+: 'root@myhost' (Using password: YES) at create.pl line 19
