How to fill `[Order]` column by order number in SQL Server?

Question

How to fill [Order] column by order number in SQL Server 2000?

For example, I have a SQL:

select Id, Tilte 
from Tbl 
order by Date

I need to write order number from this query to column [Order] of Tbl table.

How to do this?

Thanks a lot for the help!

You can use ROW_NUMBER:

WITH CTE AS
(
   SELECT Id, Title, [Order] 
   , OrderNumber = ROW_NUMBER() OVER (ORDER BY Date)
   FROM Tbl 
)
UPDATE CTE SET [Order] = CTE.OrderNumber;
