As always, backup your database before making changes.
You may need to change the "smf_" table prefix to reflect the database prefix you are actually using.
This query is for SMF 1.1.4 but may work with previous versions. You will have to check that for yourself.
ALTER TABLE `smf_members` CHANGE `hideEmail` `hideEmail` TINYINT( 4 ) NOT NULL DEFAULT '1'
