Historically, Hibernate users would have relied on the addSynchronizedQuerySpace/addSynchronizedEntityName methods of org.hibernate.SQLQuery to indicate the tables needing flushed. JPA however has no such notion.<br /><br />As I see it, I think the change here needs to be to implicitly perform a *full flush* when a JPA native SQL query is executed where the wrapped/underlying org.hibernate.SQLQuery does not define any "query spaces"; a partial flush just is not possible in that case. That allows us to pass the TCK, but still allows users to set "query spaces" if they wish to do the more efficient partial auto-flush.</span> <span class="diffremovedchars" style="background-color: #ffe7e7; text-decoration:line-through;"> </span> <span class="diffaddedchars" style="background-color:#ddfade;"> <br /><br />----<br /><br />For posterity, HEM users can still accomplish this by unwrapping to Hibernate's native {{org.hibernate.SQLQuery}} adding to the "synchronized query spaces", like:<br />{code}<br />Query jpaSqlQuery = entityManager.createNativeQuery( ... );<br />jpaSqlQuery.unwrap( org.hibernate.SQLQuery.class ).addSynchronizedEntityClass( Person.class );<br />...<br />{code}<br /><br />There are 3 forms of adding "synchronized query spaces":<br />* <br />* addSynchronizedEntityClass - Add the tables to which the given entity (by class) is mapped<br />* addSynchronizedEntityName - Add the tables to which the given entity (by name) is mapped<br /></span>
