I'm sorry, maybe you will not like my answer, but when I wanted to
find not null columns that have nulls, I wrote simple application,
with cycle for each table executing query searching for nulls in not
null columns (where field is null) by simple scanning records
with non-buffering query component (I did it with IBX.TIBSQL).

I know that it work long, but anyway, the task is to find record with
null that must not have null, so, scanning all records for the whole
database is necessary measure.

Thus, if you expert in execute statement - write it. Otherwise write
plain program with serveral simple for/while cycles.

My old app is about 70 lines in Delphi, and it is too big to post it
here. If you want me to be ashamed for the old crappy code, send me private message, I will
give you link to exe and pas sources. :-)
