I think that in your database it is :

substring(loc, 1, 3) as loc1

Anyway, the error is not where you are getting the message, the query failed
and this you don't have a valid resource to ask the number of rows or do
anything else. You should add an 'or die("message: " . mysql_error()) to
your query to trap the error.
