Thanks for the suggestions. You're quite right about
bind_columns being called after execute; I've been bitten
by that in the past.<p>
As for the 4 arguments to bind_columns, and the first
argument being undef... I believe this is an anachronism
of DBI. I just looked at the manpage, and you're right
that it seems to only expect 3 arguments, now.<p>
In the past, though, I *think* the first argument to bind_columns
was supposed to be a hash ref. So I got into the habit
of using undef as the first arg, because I never cared
about passing anything in the hash ref. I can't find that in the DBI
manpage anymore, but I did find this:
<code>
bind_columns
....
For compatibility with old scripts, if the first
parameter is undef or a hash reference it will be
ignored.
</code>
I don't remember what the hash ref was supposed to hold--nor
would I, really, since I never actually used it. :) I always
just used undef. Thanks for pointing this out.
