If you have the latest sybperl I think you can say $dbh->{UseChar} = 1
to tell sybperl to convert very large numeric values to strings
instead of numbers. The problem you are seeing is that your very large
numeric value doesn't fit in a 32 bit int.
In general I've found that using identity values beyond decimal(9,0)
creates more problems than it solves, unless you *really* expect to
have a *huge* amount of rows in your database.
