[Zope-DB] Results object

[Andrew Veitch]

Hi

I volunteered to update the Zope chapter on relational databases. I've got a
question about the Result.data_dictionary() method

It returns a dictionary of values for name, type, null and width.

Name, type and width are all pretty obvious but I've got no idea what 'null'
is. It always seems to have the value 1. I've had a look at the source and
it isn't immediately obvious.

TIA

Andrew
