We have container transaction with Spring and JPA (Hibernate). I need to make an update on a table to "flag" some rows via native statements. Then we insert some rows via EntityManager from JPATemplate to this table. After that, we need to calculate changes in the table via native statement (with Oracle's union and minus, complex groups...)

I see that changes from step 1 and 2 are not commited and thats why the statement from 3 fails. I already tried with transaction propagation REQUIRES_NEW, EntityManager.flush... Didn't work.

1) update SOMETABLE acolumn = somevalue (native)
2) persist some values into SOMETABLE (via entity manager)
3) select values from SOMETABLE

Is there a possibility to read the changes from step 1 and 2 in step 3?
