Answer / shai
select *
from user_sequences;
The last_number column will display the number available
next.
if no_cache is used in sequence definition then you can
trust on last_number column from user_sequence.
But if cache is used then below will take place:
If Cache is 20 then last_number will display any number
within range of sequence currval+20

Answer / p.rajasekar
We cannot directly get Current value from the sequence.So
first we need to get the next value, then we can get the
current value in the same scope
select sequencename.nextval from tablename
select sequencename.currval from tablename
