Question

我有这个hql查询。

Query query = session.createQuery(
                    "select inv from Invoice inv " +
                            "where 1=1  " +
                            "and inv.edited = false  " +
                            "and businessSubscription.customer.user.id = :userId " +
                            "and inv.customerInvoice is null " +
                            "and inv.parentInvoice is null order by inv.id desc " +
                            "and exists (select 1 from InvoiceItem invItm where invItm.invoice.id = inv.id and invItm.product.id in (:productIdList))"
            );

为什么会收到此异常？

org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: and near line 1, column 228 [select inv from Invoice inv where 1=1  and inv.edited = false  and businessSubscription.customer.user.id = :userId and inv.customerInvoice is null and inv.parentInvoice is null order by inv.id desc and exists (select 1 from InvoiceItem invItm where invItm.invoice.id = inv.id and invItm.product.id in (:productIdList))]

语法错误在哪里？
我认为问题出在invItm.invoice.id = inv.id上，可以在括号中使用外部别名吗？

Answer 1

您会收到此异常（unexpected token: and near line 1, column 228），因为您在and exists之后有order by inv.id desc。将exists移到您的子句中（在order by之前）。

存在子句中的Hibernate HQL语法错误
