Question 68/139
Which statement will return the last sequence number generated by the EMP_ SEQ sequence?
Correct Answer: B
* A: NEXTVAL is used to increment the sequence and return the next value; it does not give the last number generated.
* B: CURRVAL returns the current value of the sequence, which is the last value generated in the user's current session. However, CURRVAL cannot be queried unless NEXTVAL has been called at least once in that session.
* C: CURRVAL is used correctly, but the syntax 'sequence.CURRVAL' is not correct in Oracle SQL.
* D: NEXTVAL is used to generate the next sequence number, not to retrieve the last one generated.
