will help you You said that you want all booking (confirmed/cancelled) which are in future, and only cancelled bookings which are before today's date. Try following predicate for that.
code :
NSPredicate *futureBookings = [NSPredicate predicateWithFormat:@"bookingDate > %@", [NSDate date]];
NSPredicate *cancelledPreviousBookings = [NSPredicate predicateWithFormat:@"bookingDate < %@ AND cab.confirmationStatus == 1", [NSDate date]];
NSPredicate *compoundPredicate = [NSCompoundPredicate orPredicateWithSubpredicates:@[futureBookings, cancelledPreviousBookings]];

Oracle & PL/SQL Developer - Access predicates and Filter predicates no longer shown

Oracle & PL/SQL Developer - Access predicates and Filter predicates no longer shown

may help you . I'm using Allround Automation PL/SQL Developer with Oracle 10g, and today I've noticed that explain plans no longer display anything for Access Predicates or Filter Predicates. The only thing that's changed (that I know of) is that yesterday I tried using Oracle Enterprise Manager to explain a query plan, and after that PL/SQL Developer no longer populated these two columns. , Can you
code :
SELECT owner, table_name
  FROM dba_tables
 WHERE table_name = 'PLAN_TABLE'

seems to work fine No it doesn't, and it's also in the idea graveyard as something that won't be done (Predicates.sameAs). I imagine it's more or less for the reasons Mark Peters gives.

Any of those help You can't define a Realm model property in a protocol that the model class conforms to. It must be done in the class definition itself.
code :
@interface DziObject : RLMObject <StalenessChecking>
@property NSDate* refresh;
@property (getter=isStale) bool stale;
@end

I hope this helps . I agree with @lurker that this database is badly designed, but that doesn't mean you can't get some value out of it. For instance, this query will tell you all the "animals" that are mammals:
code :
  ?- current_predicate(Animal, _), 
     clause(Animal, Clause), 
     Clause = ','(mammal, _).
Animal = ungulate,
Clause =  (mammal, verify(has_hooves), !) ;

Animal = ungulate,
Clause =  (mammal, verify(chews_cud)) ;

Animal = tiger,
Clause =  (mammal, carnivore, verify(has_tawny_color), verify(has_black_stripes)) ;

Animal = cheetah,
Clause =  (mammal, carnivore, verify(has_tawny_color), verify(has_dark_spots)) ;

false.
Computed property as in predicates, and as sortProperty in RealmSearchViewController?

I think the issue was by ths following , Unfortunately, at the moment, querying for Realm objects can only be done with non-computed, Realm-persisted properties.
There's plans within Realm to add a feature where it's possible to manually sort Realm objects with a block, but there's no time frame for that yet.
