Hi
I am not sure what you are trying to attain as using something that is not
persisted will give you different results each time you query it e.g.
CREATE VIEW MYOBJECTS AS
SELECT NEWID() AS guid, * FROM SYSOBJECTS
SELECT * FROM MYOBJECTS
SELECT * FROM MYOBJECTS
If you want to rank the items then you can use a subquery e.g.
CREATE VIEW MyRanking AS
SELECT (SELECT COUNT(*) FROM SYSOBJECTS S WHERE S.ID <= O.ID) AS Rank, O.*
FROM SYSOBJECTS O
This would require the table you are using to have a method of uniquely
identifying each row.
