Greetings all,
Here is my crack at it.
we know that

$sth->{NAME_lc};
[download]

returns the column names selected and lower-cased. with that we then utilized those names as a hash slice from the hash %row with the

@row{ @{$sth->{NAME_lc}}};
[download]

part. So up to this point we have a hash %row with keys equal to the lower-cased column names returned from the query. So next we reference the slice for the bind_columns call, which we accomplish by doing an \ on the entire list; the same as saying

$sth->bind_columns(\($var1, $var2, $var3));
[download]

which would create references for each var in the list.
Nice way of doing it and probably one I will adopt in the future since I mostly use either fetchrow_hashref or just bind explicit vars.
Does that make sense?

• 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).
