我在HQL中编写了一个查询，然而，它给了我一个错误。在调查错误时，我意识到Hibernate不允许FROM中的子查询。
我是编写查询的新手，因此不知道如何将下面提到的查询转换为Hibernate接受的格式。
@Query("FROM (SELECT t, " +
"MAX(t.transactionId.versionId) OVER (PARTITION BY t.transactionId.referenceId) AS MAX_VER_ID " +
"FROM CurrentTransaction t) ABC " +
"where t.transactionId.versionId=MAX_VER_ID")
我确实知道SO不适合这样的问题，但如果有人可以帮我转换上面的Hibernate查询，那就太好了。
编辑：错误是，

我尝试了这个查询，但它也返回了一个错误，
@Query("select t from CurrentTransaction t JOIN (SELECT t.transactionId.referenceId ,MAX(t.transactionId.versionId) AS MAX_VER FROM CurrentTransaction GROUP BY t.transactionId.referenceId ) MAX_VER ON t.t.transactionId.referenceId=MAX_VER.t.transactionId.referenceId AND t.t.transactionId.versionId=MAX_VER.MAX_VER")
答案 0 :(得分：0)
您无法将使用窗口函数实现的逻辑转换为HQL / JPQL。在HQL中，这些派生表都不可能。
坚持使用SQL并可能使用本机查询来实现生成的实体：
List<CurrentTransaction> trx = em.createNativeQuery(
"SELECT t.* "
+ "FROM ("
+ " SELECT "
+ " t,*, "
+ " MAX(t.transactionId.versionId) "
+ " OVER (PARTITION BY t.transactionId.referenceId) AS MAX_VER_ID "
+ " FROM CurrentTransaction t"
+ ") t "
+ "WHERE t.transactionId.versionId = MAX_VER_ID"
, CurrentTransaction.class)
.getResultList();
注意，虽然您在某些ORDBMS中存在用于取消引用t.transactionId.versionId或t.transactionId.referenceId等嵌套记录的语法，但我怀疑您一直试图表达关系HQL中的路径。在这种情况下，您必须使用JOIN来使用经典SQL。
