Try this if you want it all in a single column:

{
    local $" = "\n";
    while ( my @row = $sth->fetchrow_array ) {
        print FINAL "@row\n\n";
    }
}

This will print each element in @row on its own line, and will print an extra blank line between each fetchrow_array iteration. I made use of the special variable $" in order to cause interpolated lists to have a \n newline placed between each element.

If you don't like to use list interpolation within a quoted construct, you can also do it like this:

{
    local $, = "\n";
    while ( my @row = $sth->fetchrow_array ) {
        print FINAL @row, "\n";
    }
}
[download]

This has the same output. You'll notice that this time I'm only explicitly printing \n once, but because it's another item in a list, it gets a \n inserted between it and the last element of @row. So again, with this method, each element of @row will be on its own line, and you'll get a blank line between records.

And if you don't like playing with special variables, here's another approach:

while ( my @row = $sth->fetchrow_array ) {
    print FINAL map( { $_ . "\n" } @row ), "\n";
}
[download]

This time map is creating a new list to be printed, based on the elements of @row with a newline appended to each element. ...and of course that trailing newline is printed too, to put a blank line between records.
