I mistyped, that should be alter table D add constraint onlyjuly check (date1 >= '2009-07-01' and date1 < '2009-08-01') Then this is also run alter table O add constraint notjuly check (NOT(date1 >= '2009-07-01' and date1 < '2009-08-01')) If I ran a select * from A where date1 >= '2009-07-02' and date1 < '2009-07-15' then I would think it wouldn't check O. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
