如何在JPARepository中編寫內部連接查詢

Question

我有以下在MySQL中完美運行的查詢，但是當我在存儲庫中編寫時會出現錯誤如何在JPARepository中編寫內部連接查詢？

@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); 

錯誤：意外的標記：鄰近線1階，柱66

Answer 1

order是一個保留字。如果不能重命名錶，你應該使用它想：

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

Answer 2

有一個在JPQL沒有ON所以查詢作爲更新：

@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); 
}
