HQl查询以从管道行检索数据

Question

I had tried to fetch data which is returning as Array in oracle which is written in a function of oracle as pipe row.

When i tried using native query like select ar_0th_element from table(fn_name(arg)).

the above code works fine in native sql query.

how to do the same thing using hql.

Answer 1

HQL, much like JPQL, are languages that are designed to work on entities . Your table-valued function TABLE(fn_name(arg)) is not an entity, so it's best to stick to native SQL.

If your table-valued function actually returns values that can be mapped to entities, you can still do this using native SQL, by calling EntityManager.createNativeQuery(String, Class)
