SQL code generation - ETL^ORM

Hibernate does SQL code generation. Often sub-optimal. Now I think ETL tools probably avoid SQL code generation. Reason is efficiency.

Suppose your legacy app has business logic in query or sproc. ETL tools often emulate the same business logic but outside the database, and often at a much faster throughput.
