Sequences and serials
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
Sequences implement the org.jooq.Sequence interface, providing essentially this functionality:
// Get a field for the CURRVAL sequence property Field<T> currval(); // Get a field for the NEXTVAL sequence property Field<T> nextval();
So if you have a sequence like this in Oracle:
CREATE SEQUENCE s_author_id
You can then use your generated sequence object directly in a SQL statement as such:
// Reference the sequence in a SELECT statement:
Field<BigInteger> s = S_AUTHOR_ID.nextval();
BigInteger nextID = create.select(s).fetchOne(s);
// Reference the sequence in an INSERT statement:
create.insertInto(AUTHOR, AUTHOR.ID, AUTHOR.FIRST_NAME, AUTHOR.LAST_NAME)
.values(S_AUTHOR_ID.nextval(), val("William"), val("Shakespeare"))
.execute();
