Is there any sample for mysql --raw??

[Weihua Wang]

I am still trying to test mysql --raw option, but I failed to get some sample for this option.
from guide, i know that --raw can disable escaped chars and output literals.

first I insert some values in test table:
mysql> insert into test values ('OK\n');
mysql> insert into test values ('OK\\n');

then do mysql login:
# mysql -uroot -p -N -s -r

do the test table query, but I still cannot find 'OK\n' value to be treated as literals. only 'OK' with new line..

How can I pass this option testing?

Can anyone give me some samples for this --raw option?
