Why?

Just check how many rows the query returned before trying to access 'em.

Think the model creation as a 2-step process: first it gets initialized 
by the columns definitions, *THEN* it gets filled by the actual rows 
returned (if any). Even if you run your query in the interactive command 
processor (psql for Postgres, don't know what's for MySql), when you run 
a query you always get an header, even when there are no rows selected.
