Rafal, the test case below is different from the one you posted yesterday.
Below you are trying to add a constraint " foreign key(nip_h,nrpok_p) references pokoje(nip_h,nrpok_p) on delete set null " though you have declared " nip_h int(10) not null " in 'rezerwacje'. InnoDB does not accept the constraint because 'on delete set null' is not sensible when you declare the column not null. I have now added a note to InnoDB manuals about this.
