Which three are true regarding the use of outer joins? (Choose three.)
A)You cannot use IN operator in a condition that involves an outerjoin.
B)You use (+) on both sides of the WHERE condition to perform an outerjoin.
C)You use (*) on both sides of the WHERE condition to perform an outerjoin.
D)You use an outerjoin to see only the rows that do not meet the join condition.
E)In the WHERE condition, you use (+) following the name of the column in the table
without matching rows, to perform an outerjoin.
F)You cannot link a condition that is involved in an outerjoin to another condition by
using the OR operator.
ANSWER: TK says D, E, F
IMO: A, E, F
