Necromaning:
If you don't want to use the SQL-Server 2000 views (deprecated), use this:

-- Restore sid when db restored from backup... 
DECLARE @Command NVARCHAR(MAX) 
SET @Command = N'ALTER AUTHORIZATION ON DATABASE::<> TO <>' 
SELECT @Command = REPLACE 
                  ( 
                      REPLACE(@Command, N'<>', QUOTENAME(SD.Name)) 
                      , N'<>' 
                      ,
                      QUOTENAME
                      (
                          COALESCE
                          (
                               SL.name 
                              ,(SELECT TOP 1 name FROM sys.server_principals WHERE type_desc = 'SQL_LOGIN' AND is_disabled = 'false' ORDER BY principal_id ASC )
                          )
                      )
                  ) 
FROM sys.databases AS SD
LEFT JOIN sys.server_principals  AS SL 
    ON SL.SID = SD.owner_sid 


WHERE SD.Name = DB_NAME() 

PRINT @command 
EXECUTE(@command) 
GO

Also prevents bug on oddly named database or user, and also fixes bug if no user is associated (uses sa login).
