Removes the ability of a user to manage passwords and administer the system privilege.
REVOKE [ ADMIN OPTION FOR ] CHANGE PASSWORD [(target_user_list | ANY | ANY WITH ROLES target_role_list )] FROM userID [,...]
REVOKE CHANGE PASSWORD (Sally, Bob) FROM Joe
REVOKE ADMIN OPTION FOR CHANGE PASSWORD FROM Sam
Depending on how the CHANGE PASSWORD system privilege was initially granted, using the ADMIN OPTION FOR clause when revoking the CHANGE PASSWORD system privilege has different results. If the CHANGE PASSWORD system privilege was originally granted with the WITH ADMIN OPTION clause, including the ADMIN OPTION FOR clause in the revoke statement revokes only the ability to administer the CHANGE PASSWORD system privilege (that is, grant the system privilege to another user). The ability to actually manage passwords for other users remains. However, if the CHANGE PASSWORD system privilege was originally granted with the WITH ADMIN ONLY OPTION clause, including the ADMIN OPTION FOR clause in the revoke statement is semantically equivalent to revoking the entire CHANGE PASSWORD system privilege. Finally, if the CHANGE PASSWORD system privilege was originally granted with the WITH NO ADMIN OPTION clause, and the ADMIN OPTION FOR clause is included in the revoke statement, nothing is revoked because there were no administrative rights granted in the first place.
You can revoke the CHANGE PASSWORD system privilege from any combination of users and roles granted.
