It's a hack for MySQL.

Displays the number of affected rows, when doing "write" type queries (insert, update, etc.).

Note: In MySQL "DELETE FROM TABLE" returns 0 affected rows. The database class has a small hack that allows it to return the correct number of affected rows. By default this hack is enabled but it can be turned off in the database driver file.
