Re: [algogeeks] DBMS gate 2012 query
Hi, Result of A U B has 5 tuples and C has 2 tuples. condition is either A.Id > 40 or C.Id < 15 First consider C.Id < 15 : 1 tuple from C satisies this condition Hence join this 1 tuple with 5 tuples of A U B = 5 new tuples A.Id > 40 yields 2 tuples from A U B - join this with the remaining tuple of C = 2 new tuples Hence 7 new tuples. --

Re: [algogeeks] DBMS
it should be 2^(m-1)-1 because in given m elements 1 element should be primary key, which will combined with other attributes to form super key. so there will be 2^(m-1) such subset now we subtract 1 for the phi.so this should be 2^(m-1)-1. correct me if i m wrong,,, -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
