Re: Tom Kyte procedure that works in 8i will not work in 9i any ideas?

Seems to work fine in 9.0.1.3.0 under Linux. Maybe a 9.0.1.0.0 bug. There was a problem with bulk insert handling nulls in arrays so there might be something similar here. Can you send a specific invocation just to be sure?

Note: seems odd that the p_n argument is a varchar2, what's that about?
