JPQL查詢，inclause

Question

我dynamicallu生成此查詢，但得到調用例外：

Select p From Product p Inner Join ProductFeatureValue pv Where p.productID = pv.productID and p.category.categoryID = 5 and pv.value in ('Blue','Black')

Answer 1

你應該做這樣的事情

和p.category .categoryID = 5和pv.value in（：colorlist） List colorlist = Arrays.asList（「Blue」，「Black」）;

q.setParameter（「colorlist」，colorlist）;

Answer 2

您的查詢無效。如果這些實體之間沒有關聯，則不能在兩個實體之間進行連接。

所以，要麼你有這樣一個協會，和查詢應該是：

select p from Product p inner join p.featureValues pv 
where p.category.categoryID = 5 and pv.value in ('Blue','Black') 

或者（如果關聯的另一面）：

select p from ProductFeatureValue pv inner join pv.product p 
where p.category.categoryID = 5 and pv.value in ('Blue','Black') 

或者你不有這樣的聯繫（但你應該擁有它），並且查詢應該是：

select p from Product p, ProductFeatureValue pv 
where p.productID = pv.productID 
and p.category.categoryID = 5 and pv.value in ('Blue','Black')
