Can anyone help me to convert this query in to 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
Here is the table relationship
482
HQL Join : HQL supports inner join, left outer join, right outer join and full join. For example, select e.name, a. city from Employee e INNER JOIN e.
Here, we use the @JoinTable annotation to specify the details of the join table (table name and two join columns - using the @JoinColumn annotation); and we set the cascade attribute of the @OneToMany annotation so that Hibernate will update the associated articles when the category is updated.
The HQL Group By clause is used to group the data from the multiple records based on one or more column. It is generally used in conjunction with the aggregate functions (like SUM, COUNT, MIN, MAX and AVG) to perform an aggregation over each group.
More than one entity can also appear in HQL which will perform cartesian product that is also known as cross join.
I have added the query for those who want to know how to JOIN multiple tables in HQL
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
