The 5/6 are quite confusing. Any what I gather from here is, that this question talks about JPQL. So things in em.createQuery(JPQL), where JPQL has to be something related to our schemas. right?
There is also createNativeQuery which does not expect JPQL, it requires native queries.
In terms of these, JPQL does not have insert statement as such.
