In my code that line is smack bang in the middle of sub connect, the
line
unless (-d "$ENV{'II_SYSTEM'}/ingres") {
to be exact.
Why on earth that fails when line 81 is
unless ($ENV{'II_SYSTEM'}) {
I can't figure out.
Possibly your lines are not the same as mine?
I am not sure that you have connected to the database at all.
The 'normal' error here is to have forgotten to set $ENV{II_SYSTEM}
correctly - I assume that you have done that.

This error comes when the first argument to $sth->bind_param is not
numeric. How that can come about if the connection fails I just can't
imagine.

Brave man!
I havn't tested DBD::Ingres with Apache::DBI (we prefer not to allow
the web server to access the database directly) so you are trampling
on relatively virgin ground.
Some parts of Apache::DBI require cached statement handles - this is
*NOT* supported by the current version of DBD::Ingres. I have been
working on it, but my supply of tuits is low again.
