Title: RE: Which method is more efficient

Jared,

Agreed, but what about the resources needs to find _which_ column changed ?? Would that offset the extra redo generated? Heck, I'd just generate the update statements based on two tables to _only_ update the changed columns. It is pretty easy, if both tables have _same_ columns ...

There are easier ways to test redo generation than mucking about with logminer.

Update only the column that changes and check redo generation:
