--本人是初学者，不知道还有没有更好的方法create table PASSWD_CHANGED

USER_NAME VARCHAR2(20),
OLD_PASSWD VARCHAR2(100),
NEW_PASSWD VARCHAR2(100)
)
CREATE OR REPLACE FUNCTION my_password_verify(username

VARCHAR2)
RETURN BOOLEAN IS
v_days NUMBER(20);
BEGIN
EXECUTE

u.username=:username'
INTO v_days
USING username;
IF v_days
< 1 THEN
raise_application_error(-20001, 'the password has
expired!'||chr(10)||'Contact :13611111111');
END IF;
/*
IF
LENGTH(password) < 6 THEN
raise_application_error(-20001,'Password must
be at least 6 characters long');
END IF;
*/
INSERT INTO
passwd_changed VALUES (username, old_password, password);
