No, it's not true. If Refresh is called and the only DML in the
transaction was inserts, then IBO will only bring over the new
rows. However, look at the RefreshAction property - this determines where
in the output set the "buffer window" is located after a Refresh. An ORDER
BY in the statement may affect the scope of a refresh, too.

See above.

No, because the PK doesn't exist in the database until the new row is
committed. If you are using AutoCommit, do make sure that your
transaction's Isolation level is tiReadCommitted. If it is tiConcurrency
and you are using AutoCommit, then your transaction won't see your inserts
after a refresh - they will seem to "disappear".
