Lemme guess, you're on Oracle and the column you keep removing to make it work is "date", right? :-) (You can't have a column called "date" in Oracle. Or "count", or "abs", etc.)

Another thing, you might want to add "use strict" at the top of your script.

Another thing, you'll want to look up "placeholders" in the DBI documentation.

Another thing, you'll want to look at using the following notation:

$sth->bind_columns(\my(
    $dates,
    $run_time,
    $run_die,
    # ...
));
