Need to reset the value of sequence in Oracle

Answer 1

This trick works for me. In my sequence (USERSUTPL_USERUTPL_SQ) the last number was 53. The last id in my table was 83

SELECT MAX(ID) FROM USERSUTPL_USERUTPL

Then 83 - 53 = 31. So:

ALTER SEQUENCE USERSUTPL_USERUTPL_SQ INCREMENT BY +31;
SELECT USERSUTPL_USERUTPL_SQ.NEXTVAL FROM dual;
ALTER SEQUENCE USERSUTPL_USERUTPL_SQ INCREMENT BY 1;

And its changes the last number. :D
