Hello monks!

I'm racking my brains here...

I'm using DBI to access a mysql database. I execute a simple select (select b from blah where user = bahbah) and put it in;

my $result = $sth->fetchall_arrayref({});

Now, I need to check whether there is anything in it or not. I had tried getting the value of;

@$result[0]->{'b'}

But Perl tells me;

Can't use an undefined value as a HASH reference


I'm hoping for some insight here.

Thanks all.
