如何在JPARepository中编写内部联接查询

Question

我有以下查询，该查询可以在MySQL中完美运行，但是在存储库中编写时却给出了错误。如何在JPARepository编写内部JPARepository查询？

@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); 

错误：意外令牌：第1行第66列附近的订单

Answer 1

order是保留字。 如果您不能重命名该表，则应按以下方式使用它：

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

Answer 2

JPQL中没有ON ，因此查询更新为：

 @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);
}
