Poor Jennifer Null - always at the mercy of poor programming. But the ghost of my favorite Tom Kyte post always returns when I hear of this kind of problem. JUST BIND!!But to any programmer, it’s painfully easy to see why “Null” could cause problems for a database. This is because the word “null” is often inserted into database fields to indicate that there is no data there. Now and again, system administrators have to try and fix the problem for people who are actually named “Null” – but the issue is rare and sometimes surprisingly difficult to solve.
