Question

Use a DB in another system with different credentials

Asked by: xchange

Dear all,

 I have created a DB being logged in as the W2k3 admin user: Steak
During creation (which was done by a script) I specified the owner to be the user: Potatoes
So, when I look up the db's properties, enterprise manager says it is owned by Steak and the dbo role is the user Potatoes with login: Potatoes.
So far so good.
Now, I backup the db and try to restore it on a foreign server that has none of the above but the sa account.
Unfortunately, when I restore it brings back the Potatoes USER in the database but not the Potatoes LOGIN in the foreign server. No matter what I do, I can not re-create the Potatoes login without getting a 'duplicate login' error although the login does not show up in the security|logins section of the server.
Result: My app tries to log-on as Potatoes and gets an error.
How can I reset the db's owner to whatever login I want?

Thank you,
--

Hi xchange,
use sp_changeDbOwner

Changes the owner of the current database.

Syntax
sp_changedbowner [ @loginame = ] 'login'
    [ , [ @map = ] remap_alias_flag ]

Arguments
[@loginame =] 'login'

Is the login ID of the new owner of the current database. login is sysname, with no default. login must be Microsoft® SQL Server™ login or a Microsoft Windows NT® user that already exists. login cannot become the owner of the current database if it already has access to the database through an existing alias or user security account within the database. To avoid this, drop the alias or user within the current database first.

[@map =] remap_alias_flag

Is the value true or false, which indicates whether existing aliases to the old database owner (dbo) are mapped to the new owner of the current database or dropped. remap_alias_flag is varchar(5), with a default of NULL, indicating any existing aliases to the old dbo are mapped to the new owner of the current database. false indicates that existing aliases to the old database owner are dropped.



Cheers!

amit_g: You were spot on!

aneeshattingal: I changed the owner another way: I detached the db and re-attached specifying the new owner.
But, although the db's owner has changed the db's children (tables, views, ...) still keep their old owner.
Will your suggestion fix the owner on all children or the db object only?

Cheers,
