如何在JPARepository中编写内部联接查询

Question

I have the following query which runs perfectly in MySQL but it gives an error when I written in repository How can I write inner join query in JPARepository ?

@Query("Select address from Address a inner join Order o ON a.id=o.pickup_address_id where o.customer_id=: customerId  AND a.address LIKE 'C%'")
     Set<Address> findPickupAddress(@Param("customerId") Long customerId); 

Error : unexpected token: Order near line 1, column 66

Answer 1

order is a reserved word. If you can't rename the table you should use it like:

@Query("Select address from Address a inner join `Order` o ON ...")

Answer 2

There is no ON in JPQL so the query is updated as :

 @Query("Select a from Address a , Order o where a.id=o.pickupAddress AND o.customer.id=:customerId  AND a.address LIKE 'C%'")
     Address findPickupAddress(@Param("customerId") Long customerId);
}
