Hello world.   
Using MyGeneration, doodads, and Oracle XE, is it possible to implement an "auto number primary key" scheme?
Problem facts:
I am using Oracle XE. I have implemented the following table and trigger:
CREATE TABLE  "USERS" 
   (    "ID" NUMBER(38,0), 
    "USER_NAME" VARCHAR2(50), 
    "PASSWORD" VARCHAR2(50), 
    "EMAIL" VARCHAR2(100), 
     CONSTRAINT "USERS_PK" PRIMARY KEY ("ID") ENABLE
   )
/
CREATE OR REPLACE TRIGGER  "BI_USERS" 
  before insert on "USERS"               
  for each row  
begin   
    select "USERS_SEQ".nextval into :NEW.ID from dual; 
end; 
/
ALTER TRIGGER  "BI_USERS" ENABLE
/
MyGeneration / Doodads created the following stored proc...
CREATE OR REPLACE PROCEDURE "XXX"."PI_USERS"
(
    p_ID IN USERS.ID%type,
    p_USER_NAME IN USERS.USER_NAME%type,
    p_PASSWORD IN USERS.PASSWORD%type,
    p_EMAIL IN USERS.EMAIL%type
)
IS
BEGIN
    INSERT
    INTO USERS
    (
        ID,
        USER_NAME,
        PASSWORD,
        EMAIL
    )
    VALUES
    (
        p_ID,
        p_USER_NAME,
        p_PASSWORD,
        p_EMAIL
    );
END PI_USERS;
The sequence and trigger combination is working fine.   The BusinessEntity class in C# does not receive the new ID.
Any recommended ways to allow the calling code receive the new record ID?
