I was considering why some special commands in mysql like
drop user when correct passed return
"0 rows affected", which is not true! (rows in mysql db are affected indeed)
I know there are not standard queries, but if we do
delete from user where ... on
mysql database, we will see
N rows affected.
so it's countable in rather easy way.
otherwise response "Query OK (0.00 sec)" will be much accurate.
or am I missing sth? I verify above with a few mysql version 5.1-5.5.
