( #3333=superdoc: print w/replies, xml ) Need Help??
my @columns = map { substr($_,1) } keys %{$q{'-values'}};
Um, all that does is create a list of the columns with the first letter of the column name missing...

Anyhow, about specifying the columns in any order in the SQL query, would the following code always work correctly?

my $ph = join ', ', ('?') x values %{$q{'-values'}}; my $sth = $self->{$db_handle}->prepare( "INSERT INTO $q{'-table'} (" . join(',', keys %{$q{'-values'}}) . ") VALUES($ph)" ); $sth->execute(values %{$q{'-values'}});

All I'm really asking is whether the order of keys %hash and values %hash are always the same in perspective to each other...

Update: lol, as soon as I finished posting this post, your update was there :) I understand now why you supplied the code you did. It was to get rid of the hyphens you thought were there :)

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).
