How to check current sequence value in Oracle?
To check the current sequence value in Oracle, you can use the following SQL query:
SELECT sequence_name.currval from dual;
This query will return the current value of the sequence.

ALTER SEQUENCE sequence_name RESTART;
2. Can I check the last value generated by a sequence in Oracle?
Yes, you can check the last value generated by a sequence in Oracle by using the following SQL query:
SELECT sequence_name.last_number FROM user_sequences;
3. How can I increment a sequence by a specific value in Oracle?
To increment a sequence by a specific value in Oracle, you can use the following SQL query:
ALTER SEQUENCE sequence_name INCREMENT BY value;
4. Is it possible to check the minimum and maximum values of a sequence in Oracle?
Yes, you can check the minimum and maximum values of a sequence in Oracle by using the following SQL query:
SELECT min_value, max_value FROM user_sequences WHERE sequence_name=’my_sequence’;
5. How can I check the cache size of a sequence in Oracle?
To check the cache size of a sequence in Oracle, you can use the following SQL query:
SELECT cache_size FROM user_sequences WHERE sequence_name=’my_sequence’;
6. Can I check if a sequence is set to cycle in Oracle?
Yes, you can check if a sequence is set to cycle in Oracle by using the following SQL query:
SELECT cycle_flag FROM user_sequences WHERE sequence_name=’my_sequence’;
