I think if you leave it out, you probably won't see your comments. The proper usage would be to test if there is a result set before trying to count it. I'll try to post an example, but I can barely type on the computer I'm on...

EDIT

Here's a little code snippet I took out of one of my projects:

Code:

if($query->num_rows() > 0)
{
    return $query->result();
}

This makes sure that there is a result set to count while attempting to count it.
