Hello friends .....I am stuck at one question in perl....I have wrote a subroutine which is called by someother subroutine.....The task of this subroutine is to insert value in database.The sub routine is as follows:

sub _get_user_scenario
{
    my ($self, $schema, $user_scenario) = @_;
    
    my $user_scenario_rs = undef;
    eval
    {
#get the number of user scenarios in the database table
my $count = $schema->resultset("UserScenario")->count();
        
#insert user scenario, or if already in database, update the descripti
+on
$user_scenario_rs =
            $schema->resultset("UserScenario")->update_or_create(
                { name  => $user_scenario->{name},
description => $user_scenario->{description}, },
                { key   => "u_user_scenario_name" },
            ) || die "Unable to update/insert data to table UserScenar
+io: $!\n";
    };
    
    if($@)
    {
        #warn();
        $self->log_writer()->write_error_row("Unable to get/insert dat
+a to table UserScenario: $@");
        return undef;
    }
    else
    {
        return $user_scenario_rs;
    }
}

If $user_scenario->{description} is empty then I don't want to replace the description for the existing sceanrio.And I wanna keep the value which is already there in the database for that scenario.How to achieve it?Any suggestions? Thanks in advance!!!!
