in reply to Array of Hashes

Hi, you are debugging with:

$field1 = $row->{field1}; $field2 = $row->{field2}; $field3 = $row->{f +ield3}; print "Row id is $field1, field 2 is $field2, field 3 is $field3\n";

You might like sprintf, you can skip all that assigning to temporary variables just to debug an interpolated string:

print sprintf "Row id is %s, field 2 is %s, field 3 is %s\n", @{$row}{ +qw/field1 field2 field3/};

Hope this helps!

    Why print sprintf ... instead of printf ...?

    Optimising for fewest key strokes only makes sense transmitting to Pluto or beyond

      Hi Grandfather, because I would use

      say()
      but didn't want to introduce that change in my comment.

      And because usually I am doing

      $log->debug(sprintf 'format', @values)
      or even
      $msg = sprintf 'format', @values; $DEBUG && say $msg && $log->debug($msg);

      Basically, I've never used printf alone in the last 20 years, because it does not meet my needs.
