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.
