Using 5.8.2, Adapter

In earlier versions I used GetFieldPersistenceInfo() and InsertPersistenceInfoObjects() in a custom DataAccessAdapter to retrieve SQL names and predicates, but these methods are not available anymore.

What is now the best way to retrieve the persistence info?

They have been moved to the QueryCreationManager class.

Please follow the instructions mentioned in the docs(here)

Oops, missed that. Thanks for pointing it out.
