Hi,

just a simple question:

How can I set a field NOT NULL constraint afterwards.
There is a lot of data in that table and too much depencies
so I cannot drop and recreate that field again.

I suppose "DEFAULT 0"  would also be enough.

This is a problem because I have triggers which
increment and decrement that value and that can't be done
if value is NULL.

Thanks for reading
Mika Parjanen
