OOPs! I misquoted fetchall the quote was from fetchrow. Bad, Bad starbolin. But, now I notice that you do not use the value returned from fetchall. How come? I would expect to see something like print @{$row} where $row is dereferenced back to an array or foreach @{$row} { do-something-with-$_ } to loop over the data in the array referenced by $row.

Do you understand references? Do these statements make sense? If not, perhaps a read of perlreftut is in order.
