I need to get the sequence value of a table before inserting a new record, so I am using currval, but I am getting an error stating that "currval is not defined for this session". I tried using nextval, but the sequence skips one value because nextval increments by one and also an additional increment is preformed by the insert operation.
How can I get the next available value avoiding these issues?
