RE: Sql Question

See inline

I have an SQL statement that compares data in for one table in two
different
libraries. The SQL just says report any record where the initials are
different but when I run it I get nothing.

I had one record where the initials for in one record was Null and in
the
other FUL but the SQL reported them as equal. That doesn't make much
sense.

Agreed.

Does SQL bypass the test if one side is null?

No, it doesn't do that.

Isn't null just a absence of
data so they would not be equal?

That's right.

Have I found a bug (A big one?

Probably not. More likely it's an error in your JOIN or WHERE or whatever
you're doing to combine/compare the two tables. Since you have elected not
to share any code, it's difficult to go further.
