Affected Rows won't work when using batch insert/update

That's odd.

affected_rows() just calls the selected drivers' PHP function. As insert_batch() inserts the data with 100 rows at the same time, the figure could be incorrect (as you'll only see the last insert operation), but you see something else than zero.

Are you using transactions? If so, after a commit, the counter is reset to zero.
