db_owner and login

I am trying to restore a database on DR server, after my restore, i cannot
use the ID to login to the application. 3 observations:
1) I am using scripts, so all my commands are in SQL statements. Here is my
script for restoring the database:
Alter database FRR_SGMAS set single_user with rollback immediate
go
restore database FRR_SGMAS from DISK='F:\program files\microsoft sql
server\mssql\backup\frrsgmas_b.dmp'
WITH MOVE 'FRR_SGMAS_Data' TO 'F:\Program Files\Microsoft SQL
Server\MSSQL\data\FRR_SGMAS_Data.mdf',
MOVE 'FRR_SGMAS_Log' TO 'F:\Program Files\Microsoft SQL
Server\MSSQL\data\FRR_SGMAS_Log.ldf',
FILE = 1
go
Alter database FRR_SGMAS set multi_user
go
2) At the security of DR server level, the ID was not granted the rights to
access the database. I need to re-grant the rights.
3) The ID need db_owner rights, I notice if i have 2 IDs, it is impossible
to grant 2 IDs with db_owner rights by script.
As a result, I cannot login to this application, since the ID does not have
DB_owner access. The application require the ID to have db_owner access.
How can i grant the rights by running SQL script? As I mentioned before, i
have 2 ID that needs to have db_owner rights.
I have tried to drop user and login, and add user and login. However, i am
still not sure how can i add dbowner roles to the ID. I tried
sp_changedbowner, however, i cannot do it to another user.
Thanks for the help in advance.
Have you tried using sp_change_users_login? Please see BOL for details of
this command.
