BUG #: 16830



SYMPTOMS
You may experience the following error message when a database owner (DBO) assigns permissions for a view that contains 2^N - 1 columns, where N is >= 3 (such as 7, 15, 31, 63... in decimal or 111, 1111, 11111, 111111... in binary):

Msg 4601, Level 16, State 1

Only owner <%.*s> of object <%.*s>,in database %.*s

can GRANT/REVOKE this permission.

The following scripts demonstrate this problem:

Step 1: Connect to SQL Server as a systems administrator (SA) from ISQL/w.

USE pubs GO  sp_dropalias pubsdbo GO  sp_droplogin pubsdbo GO  sp_addlogin pubsdbo, NULL, pubs GO  sp_addalias pubsdbo, dbo GO  SETUSER GO  IF EXISTS (SELECT NULL FROM sysobjects      WHERE id = object_id('user1.user1view') and type = 'V') DROP VIEW user1.user1view GO  sp_dropuser user1 GO  sp_dropuser user2 GO  sp_droplogin user1 GO  sp_droplogin user2 GO  sp_addlogin user1, NULL, pubs GO  sp_addlogin user2, NULL, pubs GO  sp_adduser user1 GO  sp_adduser user2 GO  GRANT CREATE VIEW TO user1 GO  SETUSER 'user1' GO  IF EXISTS (SELECT NULL FROM sysobjects     WHERE id = object_id('user1.user1view') and type = 'V') DROP VIEW user1.user1view GO  CREATE VIEW user1view AS SELECT 1 as c1, 2 as c2, 3 as c3, 4 as c4, 5 as c5, 6 as c6, 7 as c7  GO   GRANT ALL ON user1view TO DBO WITH GRANT OPTION GO  SETUSER GO

Step 2: Connect to SQL Server and log on as "pubsdbo" with no password.

GRANT SELECT ON user1.user1view TO user2 GO



WORKAROUND
To work around this problem, create a view with the number of columns that has fewer or more than 2^N - 1 columns, where N >= 3.



STATUS
