Dear all

I have a question here hopy you guys can help me.
I tried to delete some of the transactions, then export the whole
db out, and then import it back and check on the size. but I noticed that
when I check it from the oracle enterprise manager, the number of rows still
the same as before deleting, but when I check using the sqlplus, apparently,
the number of rows decreased. Why? and what should i do if i really want to
know the exact size of the database after deleting?

Please help. Thank you
