clarification on docs pg 53 transaction control methods

pg 53 Tansaction Control Methods

"By default iBATIS does not actually commit unless it detects that the
database has been changed by a call to insert, update or delete. If
you’ve somehow made changes without calling these methods, then you
can pass true into the commit and rollback methods to guarantee that
it will be committed"

What would be an example of changes done 'without calling these
methods' where you might want to force a commit with true?  Are you
referring to an external manipulation of the row in question from
outside the app (ie manual update.)

I assume it won't hurt anything to always be safe and call
commit(true) on the inserts,updates, deletes ?

A case would be something like a stored proc that does a bunch of stuff,
then returns a bunch of stuff... where some of that stuff includes updates.
If you call that with the  .selectList() method, then you'll want to call
commit(true).

It's rare, but happens.
