The question here is to List the details of all the tours for cruise number 373 that did not attract any passengers in 2011.
I was trying to solve this problem by using MINUS or NOT IN statement, but none of them worked, so can you please help me? Thanks a lot.
PS: Do I need to post all the CREAT TABLE and INSERT VALUE queries?

Answer 1

the posting all the CREATE TABLE and INSERT's are helpful...
-- List the details of all the tours for cruise number 373 in 2011
select t.*
from TRAVEL tr, TOUR t
where
tr.TOURID  = t.TOURID
and CRUISEID = 373
and to_char (TOUR_DATE ,'YYYY') = '2011'
-- List passengers of all the tours for cruise number 373 in 2011
    select *
    from TOUR_PARTICIPANT p
    where p.CRUISEID  = tr.CRUISEID -- =373
    and p.TOURID = t.TOURID -- Tours for CRUISEID = 373 in year 2011
-- If exist tour for CRUISEID = 373 in year 2011 and not exists passengers [PASSID] then:
select t.*
from TRAVEL tr, TOUR t -- (List the details of all the tours for cruise number 373 in 2011)
where
tr.TOURID  = t.TOURID
and CRUISEID = 373
and to_char (TOUR_DATE ,'YYYY') = '2011'
and not exists -- (List passengers of all the tours for cruise number 373 in 2011)
    select 1
    from TOUR_PARTICIPANT p
    where p.CRUISEID  = tr.CRUISEID
    and p.TOURID = t.TOURID
    )
