Here is my crack at it.
we know that
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
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));
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?
