( #3333=superdoc: print w/replies, xml ) Need Help??

I'm not interested in regexps as I'm not working with strings. This is being used to update database fields, so unless you're doing some really fancy tie-ing, regexps aren't gonna fly :)

For reference, the heart of the code that uses this snippet looks like this:

my $db = DBI->connect( $DSN, 'user', 'sekret', {AutoCommit => 0}) or die "Couldn't connect to database $DSN: ${\DBI->errstr}\n"; END { $db and $db->disconnect } my $ss = $db->prepare( q{update t set department = ? where department += ?}); die unless $ss; my $ok = 1; REPLACE: for my $r( @order ) { for my $key( keys %$r ) { print "$key -> $r->{$key}\n"; if( !$ss->execute( $r->{$key}, $key )) { warn "cannot update $key to $r->{$key}\n${\$ss->errstr}\n" +; $ok = 0; last REPLACE; } } } $ok ? $db->commit : $db->rollback;

NB: The above code is condensed from production code. I have excised things that have no relevance to the example, so it just may or may not compile :)

print@_{sort keys %_},$/if%_=split//,'= & *a?b:e\f/h^h!j+n,o@o;r$s-t%t#u'

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
