BUG: Use of Sp_dboption by an Aliased DBO Fails with Error 15244

• Microsoft SQL Server, versions 6.0 and 6.5

       15545 (6.0)

SYMPTOMS

When an aliased database owner (DBO) attempts to change any of the database options using the sp_dboption system stored procedure, the following error message is raised from the stored procedure:

   Msg 15244, Level 16, State 1
   Only the System Administrator (SA) or the owner of the database may set
   db options

Assume you have a login name of Raj aliased as the DBO in the pubs database. Log on as Raj and try to change the database option for the pubs database by executing the command below. You will encounter the error message described above.

   sp_dboption pubs, 'single', true

CAUSE

SQL Server incorrectly checks the user validation in the sp_dboption system stored procedure for aliased DBOs.

WORKAROUND

To work around this problem, log on as a system administrator (SA) to be recognized as the only DBO who will be able to make database option changes using the sp_dboption system stored procedure.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server versions 6.0 and 6.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
