USERNAME PASSWORD PACKAGE/Procedure in PL/SQL

I have oracle 9.2.01 release 2.  Im looking to find pl/sql code that will let users set a username and password.  I would like to store that uname and pword into a table.  Then if the user comes back, they will be able to use the uname and pword to log back in to the gateway to the web system.  ANY HELP IS APPRECIATED>> SAMPLE CODE OF SOMETHING SIMILAR WOULD BE GREAT!!!!

Here's a SQL script for you to adapt to pl/sql, i've included the part you need to insert the us/pw into a table  :

Do you need something more ? Is this working for you ?
Is that was you needed ?

IT NEEDS TO BE IN PL/SQL!!!
Ok, It's just because I read in the post
ANY HELP IS APPRECIATED>> SAMPLE CODE OF SOMETHING SIMILAR WOULD BE GREAT!!!!

I thought you were able to convert this logic to pl/sql.
Here's a pl/sql one :

REM alterpwd.sql
create or replace procedure CHANGE_MY_PASSWORD(NewPass IN VARCHAR2) AS
    Cursor_Name INTEGER;
    String VARCHAR2(100);
    cursor USERNAME_CURSOR is
      select User from DUAL;
    UserNm VARCHAR2(32);
BEGIN
   open USERNAME_CURSOR;
   fetch USERNAME_CURSOR into UserNm;
   close USERNAME_CURSOR;
   String:= 'alter user '||UserNm||' identified by '||NewPass ;
   Cursor_Name := DBMS_SQL.OPEN_CURSOR;  
   DBMS_SQL.PARSE(Cursor_Name, String, dbms_sql.Native);
   DBMS_SQL.CLOSE_CURSOR(Cursor_Name);
END;
/


You could use the insert command also to insert the username and password in a table if you want.
With 2 input variables

create or replace procedure CHANGE_MY_PASSWORD(Newuser IN VARCHER2 NewPass IN VARCHAR2) AS
    Cursor_Name INTEGER;
    String VARCHAR2(100);
    UserNm VARCHAR2(32);
    PassNm VARCHAR2(32);
BEGIN
   String:= 'alter user '||UserNm||' identified by '||NewPass ;
   Cursor_Name := DBMS_SQL.OPEN_CURSOR;  
   DBMS_SQL.PARSE(Cursor_Name, String, dbms_sql.Native);
   DBMS_SQL.CLOSE_CURSOR(Cursor_Name);
   String:= 'insert into yourtab select '''||UserNm||''','''||NewPass||'''||' from dual' ;
   Cursor_Name := DBMS_SQL.OPEN_CURSOR;  
   DBMS_SQL.PARSE(Cursor_Name, String, dbms_sql.Native);
   DBMS_SQL.CLOSE_CURSOR(Cursor_Name);
END;
/

I WOULD WORSHIP ANYONE WHO CAN HELP WITH THE FOLLOWING:  I need to translate this small piece of php into something that would work with an oracle DB.  As it reads right now, it is setup to interface with mySQL.  I have been using the OCI and ORA functions through PHP and I cant get it to work right.  SOMEONE HELP PLEASE

User Authentication-Version 1.3
Written and designed by Jaime R. Gouveia-Snap Survey Software 2003
This page is designed for authenticating users to log into specific surveys.

The only configurations that may need to be adjusted are for the validation of username and password lengths.
Nothing else should need to be modified.

By default, the data entered for the password is required to be 5 characters. Username has no restriction on the length. However, the username can only be alphanumeric characters, spaces and underscores.

10/24/03-Added validation of data. Need to include a validation for illegal characters in the username.
10/27/03-Added validation for illegal characters. Starting to tweak query for db.
