in reply to DBI execute() args in array format (or similar) possible?

In your specific case, instead of using placeholders, you could try building the SQL SELECT stmt based on the number of arguments present. For example,
$sql = "select clli, traffic_date, count(distinct(traffic_hour)) from gvc_traffic30 where 1=1 "; $sql .= " and traffic_Date in ($date_ref_args) " if ( $date_ref_args ) +; ...etc...
The "1=1" part enables you to add a dynamic number of "And " clauses without any problems...

[tye]: disable /proc and then see what it does?
[davido]: then it reads from /etc/passwd to decide who my uid is.
[davido]: sorry, typed that before you asked me to disable proc
[davido]: but you stumped me; don't know how to disable proc.
[tye]: I don't know if you can just dismount, but I thought so.
[davido]: yeah, umount -f isn't powerful enough.
[tye]: probably something in the init subsystem that does the mounting that you could disable and reboot.
davido needs to close laptop to board flight home from yapc.
[davido]: I'll look into it in a few hours probably.
[davido]: when i do get to that point I think I'll do it in a vm snapshot just in case. :)
