Database Diagram Support Objects cannot be Installed … no valid owner

StackOverflow https://stackoverflow.com/questions/2043382

Question

I tried to create a database diagramm with SQL Server 2008, but an error occurs:

Database diagram support objects cannot be installed because this database does not have a valid owner. To continue, first use the Files page of the Database Properties dialog box or the ALTER AUTHORIZATION statement to set the database owner to a valid login, then add the database diagram support objects.

Then I tried the following:

EXEC sp_dbcmptlevel 'Ariha', '90';
GO
ALTER AUTHORIZATION ON DATABASE::Ariha TO [WIN-NDKPHUPPNFL\Administrator]
GO
USE Ariha
GO
EXECUTE AS USER = N'dbo' REVERT
GO

Next erorr pops up:

Msg 15404, Level 16, State 11, Line 1 Could not obtain information about Windows NT group/user 'WIN-NDKPHUPPNFL\Administrator', error code 0x534.

The Problem is the name of the PC has changed into "DevPC" I also changed this in the update script, but still the same error 15404.

What can I do to fix this annoying error?

Was it helpful?

Solution

You should consider SQL authentication account for database ownership; then you don't have to worry about accounts coming and going, databases or instances moving to different servers, and your next PC name change. I have several systems where we use:

ALTER AUTHORIZATION ON DATABASE::Ariha TO [sa];

Or if you want to change the owner to that local Administrator account, then it should be:

ALTER AUTHORIZATION ON DATABASE::Ariha TO [DevPC\Administrator];

Because renaming the machine to DevPC has eliminated the local account that used to be named WIN-ND...\Administrator and this has also invalidated the current owner of the database.

If SELECT @@SERVERNAME; is not accurate (it should say DevPC), then in order to ensure that your server rename has taken hold within SQL Server, you may also want to issue the following:

EXEC sp_dropserver @server = N'old server name';
GO
EXEC sp_addserver @server = N'DevPC', @local = N'local';
GO

OTHER TIPS

In SQL Server Management Studio do the following:

  1. Right Click on your database, choose properties
  2. Go to the Options Page
  3. In the Drop down at right labeled "Compatibility Level" choose "SQL Server 2005(90)" 3-1. choose "SQL Server 2008" if you receive a comparability error.
  4. Go to the Files Page
  5. Enter "sa" in the owner textbox. 5-1 or click on the ellipses(...) and choose a rightful owner.
  6. Hit OK

after doing this, You will now be able to access the Database Diagrams.

enter image description here

USE [ECMIS]
GO
EXEC dbo.sp_changedbowner @loginame = N'sa', @map = false
GO

It works.

Enter "SA" instead of "sa" in the owner textbox. This worked for me.

I had the same problem.
I wanted to view my diagram, which I created the same day at work, at home. But I couldn't because of this message.
I found out that the owner of the database was the user of my computer -as expected. but since the computer is in the company's domain, and I am not connected to the company's network, the database couldn't resolve the owner.

So what I did is change the owner to a local user and it worked!!
Hope this helps someone.

You change the user by right-click on the database, properties, files, owner

This fixed it for me. It sets the owner found under the 'files' section of the database properties window, and is as scripted by management studio.

USE [your_db_name]
GO
EXEC dbo.sp_changedbowner @loginame = N'sa', @map = false
GO

According to the sp_changedbowner documentation this is deprecated now.

Based on Israel's answer. Aaron's answer is the non-deprecated variation of this.

Select your database - Right Click - Select Properties

Select FILE in left side of page

In the OWNER box, select button which has three dots (…) in it

Now select user ‘sa and Click OK

I just experienced this. I had read the suggestions on this page, as well as the SQL Authority suggestions (which is the same thing) and none of the above worked.

In the end, I removed the account and recreated (with the same username/password). Just like that, all the issues went away.

Sadly, this means I don't know what went wrong so I can't share any thing else.

1.Right click on your Database , 2.Then select properties . 3.Select the option in compatibility levels choose sql 2008[100] if you are working with Microsoft sql 2008.

4.Then select the file and write ( sa ) in owner`s textbox

100% works for me.

An easier way to solve this issues would be to right click the name of your database, choose "New Query", type " exec sp_changedbowner 'sa' " and execute the query. Then you'll be good to go.

you must enter as administrator right click to microsofft sql server management studio and run as admin

Only need to execute it in query editor ALTER AUTHORIZATION ON DATABASE::YourDatabase TO [domain\account];

The real problem is that the default owner(dbo) doesn't have a login mapped to it at all.As I tried to map the sa login to the database owner I received another error stating "User,group, or role 'dbo' already exists...".However if you try this code it will actually works :

EXEC sp_dbcmptlevel 'yourDB', '90';

go

ALTER AUTHORIZATION ON DATABASE::yourDB TO "yourLogin"

go

use [yourDB]

go

EXECUTE AS USER = N'dbo' REVERT

go

right click on your Database , then select properties . select the option in compatibility levels choose sql 2005[90] instead of 2008 if you are working with Microsoft sql 2008. then select the file and write ( sa ) in owner`s textbox. it will work probably
