fetch() add row =null

[Former user]

When i use the

$rows = $db->from('mytable')->fetch();
$affected = $db->affected_rows ;   that's right, i have the good result.
but the array "$rows" has a line add at the end = null

I am unable to duplicate the issue. It returns the result correctly. I can take a look at your code if you share to see what is going on.
