In Hibernate how to ignore associated table in selection - spring-boot

Question

I am using spring boot and Hibernate and I have two tables order and orderdetails and I need two queries, first I want to select records in order along with records that relate to that order in order detail table which works fine, but when I want to select only records from order table I can't because it will bring all associated records for each order in the order detail(just like the first one). How I can select records from the order without selecting related records in order detail table?
I also tried to use #JsonIgnore annotation but it doesn't work like what I want.
My entity classes
orders
#Entity
#Setter
#Getter
public class Orders {
#Id
#NotNull
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "order_id")
private Long orderId;
#Column(name = "user_id")
private Long userId;
#Column(name = "user_name")
private String userName;
#Column(name = "created_date", columnDefinition = "DATE")
#JsonFormat(pattern = "MM/dd/yyyy")
private LocalDate createdDate;
private String status;
private float amount;
#Transient
String error;
#OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
#JoinColumn(name = "order_id")
private List<OrderDetail> orderDetails;
}
order detail
#Entity
#Setter
#Getter
public class OrderDetail {
public OrderDetail() {
}
public OrderDetail(Long productId, String productName, int quantity, float unitPrice, float subtotalPrice){
this.productId = productId;
this.productName = productName;
this.quantity = quantity;
this.unitPrice = unitPrice;
this.subtotalPrice = subtotalPrice;
}
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "order_detail_id", nullable = false)
Long orderDetailId;
#Column(name = "product_id")
Long productId;
#Column(name = "product_name")
String productName;
int quantity;
#Column(name = "unit_price")
float unitPrice;
#Column(name = "subtotal_price")
float subtotalPrice;
}
Queries that I tried:
#Query(value = "select orders.order_id, orders.amount, orders.created_date, orders.status, orders.user_id, " +
"orders.user_name from orders where orders.user_id = :userid", nativeQuery = true)
List<Orders> selectAllOrdersOfSpecificUser(#Param("userid") Long userId);
==================================================================================
List<Orders> findAllByUserId(Long userId);
Both of them bring all the records from the orders table and associated records in the order detail table.

Answer 1

FetchType.EAGER will retrive all the orderdetails as well. Use FetchType.LAZY and create a special JOIN FETCH query for getting orderdetails with orders.
