How do you perform a JOIN operation using jOOQ?

A) join()
B) link()
C) combine()
D) connect()

Answer:

A) join()

Explanation:

The join() method in jOOQ is used to perform a JOIN operation between two or more tables. It allows you to combine rows from different tables based on a related column between them.

For example:


DSLContext create = DSL.using(configuration);

Result<Record> result = create.select()
                              .from(TABLE1)
                              .join(TABLE2)
                              .on(TABLE1.FIELD1.eq(TABLE2.FIELD2))
                              .fetch();

In this example, the join() method is used to perform an inner join between TABLE1 and TABLE2.
