Answer Posted / ankit sinha
equijoin will produce only the common record.
A right outerjoin B will produce all common records with
remaining records from B . The point to be noticed here is A
is right outerjoined to B which means common records from A
as well as remaining records from B
Opposite things happen with A left outerjoin B
Full outer join means common records and remaining records
from both the tables
crossjoin means multiplications
suppose A has 4 records and B has 4 records.
Total output will have 16 records.
