How to Use a boolean function in a process

Question

Hi,
I created a boolean function named change_pwd with 3 varchar2 parameters : login_name, old-pwd and new_pwd. I would like to use it in a process but I can't, this is how I do it :<br><br>
select change_pwd (
v('P12_Login'),v('P12_Old_Pwd'),v('P12_New_Pwd')) from dual;
<br><br>

I got this error : <br><br>
ORA-06550: line 2, column 8: PLS-00382: expression is of wrong type ORA-06550: line 2, column 1: PLS-00428: an INTO clause is expected in this SELECT statement
<br><br>
and here is my function :<br><br>
create or replace function "CHANGE_PWD"<br>
(p_username in VARCHAR2,<br>
p_old_password in VARCHAR2, <br>
p_new_password in VARCHAR2)<br>
return boolean<br>
is<br>
l_count number;<br>
l_password varchar2(4000);<br>
l_stored_password varchar2(4000); <br>
l_idcontact number;<br>
begin<br>
-- Check to see if the user is in the user table<br>
select count(*) into l_count from CONTACTS where MATRICULE = p_username;<br>
if l_count > 0 then<br>
-- take the stored password<br>
select u.MOTDEPASSE, u.IdContacts into l_stored_password, l_idcontact from <br>UTILISATEURS u, CONTACTS c where u.IdContacts = c.IdContacts AND c.MATRICULE = p_username;<br>
<br>
-- apply the cash function<br>
l_password := user_hash(p_username, p_old_password);<br>
<br>
-- compare the hashed password with the stored password<br>
if l_password = l_stored_password then<br>
-- change password<br>
update UTILISATEURS set MotDePasse = user_hash(p_username, <br>p_new_password) where idcontacts = l_idcontact;
return true;<br>
else<br>
return false;<br>
end if;<br>
else<br>
return false;<br>
end if;<br>
end;<br>
