Hello There,

So, I might get burned for asking this, but it has been on my mind and I want to really understand.

I tend to avoid using -w for one reason, it complains about a habit I have. I like to do this: 

my $query = "SELECT something FROM somewhere";
my $sth = $dbh->prepare($query);
my $rv = $sth->execute;
my $first_result = $sth->fetchrow_hashref;

my $query = "SELECT somethingelse FROM somewhereelse";
my $sth = $dbh->prepare($query);
my $rv = $sth->execute;
my $second_result = $sth->fetchrow_hashref;

... then do something with $first_result and $second_result

Is this really *that* bad? If so why? And how would you rewrite the same block? Just omit the my's or use different variable names?

Also, if I "reuse" $query, $sth, $rv several times (as in the above example) what is actually happening in memory?

Thanks for your insight and helping me be a better Perl programmer :)
