Database Diagram Support Objects cannot be Install

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?

Answer 1

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.

Answer 2

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

Answer 3

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.

Answer 4

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

Answer 5

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

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
