Re: Problem: Like-Statement and NULL-Fields

Hi,

of course
SELECT * FROM Users WHERE Flags is not null and flagsNOT LIKE 'D%'; would do, but you said, you can't change the select-statement

so, change the table-def.
a. rename users to users_
b1. create view users as select * from users_ where flags is not null; or
b2. create view users as select bla1, bla2, ..., blam, nvl(flags, ' ') as flags from users_;

in case b2 U might have to use instead-of-triggers for dml on users
