immediately where as the other takes about 10 seconds before the first
row is returned.

I am trying to add a unique constraint on a column that can be null. The
documentation states that null is treated as non equal values but I want
them to be equal. Is there another way of doing this other than writing
a before insert trigger?

Yup that's what happened. Dropped them and all is good. I really should

see if any others are missing.

I would like to know if I can update part of a column. ie
update myfile set substr(direct_key,1,10)='1234567890' where
substr(direct_key,1,10)='0987654321';
This does not work. Is this possible? Or am I looking at this the wrong
way?
