在HQL中加入多个表

Question

任何人都可以帮助我将此查询转换为HQL

SELECT      
  supplierOrderDetails.productID,
  supplierOrderDetails.orderQty,
  supplierOrderReceiveDetail.qtyArrived
FROM
 supplierOrder
INNER JOIN
  supplierOrderDetails
ON
  (supplierOrderDetails.supplierOrderID = supplierOrder.ID)
INNER JOIN 
    supplierOrderReceive
ON  
 (supplierOrderReceive.supplierOrderID = supplierOrder.ID)
INNER JOIN 
    supplierOrderReceiveDetail
ON  
 (supplierOrderReceiveDetail.supplierOrderReceiveID = supplierOrderReceive.ID)  
   AND 
 (supplierOrderReceiveDetail.ProductID =supplierOrderDetails.ProductID)     
WHERE supplierOrder.ID = 1

这是表关系

Answer 1

我为那些想知道如何在HQL中联接多个表的人添加了查询

SELECT supplierOrderDetails.productID as product, supplierOrderDetails.orderQty as orderedQty,sum(supplierOrderReceiveDetail.qtyArrived) as qtyArrived 

FROM SupplierOrder as so, SupplierOrderDetails as supplierOrderDetails,  SupplierOrderReceiveDetail as supplierOrderReceiveDetail, SupplierOrderReceive as supplierOrderReceive

INNER JOIN supplierOrderDetails.supplierOrderID

INNER JOIN supplierOrderReceive.supplierOrder

INNER JOIN supplierOrderReceiveDetail.supplierOrderReceive

GROUP BY supplierOrderDetails.productID, supplierOrderDetails.orderQty

要使休眠连接实体，您必须定义实体之间的关联/映射。
Hibernate 使用 Hibernate 映射文件中定义的关系名称。
