Please Help Me Populate My Date Fields

Hi,

I have the following table:

CREATE TABLE [Orders] (
[OrdID] [int] ,
[OrderDate] [datetime] ,
[OrderDateONLY] [datetime],
[OrderDayName] [nvarchar] (15),
[OrderMonth] [nvarchar] (25),
[OrderDayOfMonth] [smallint] NULL ,
[OrderWeekofYear] [smallint] NULL
)
GO

The field OrderDate contains BOTH Date and Time information. What I want to do is populate the fields (in bold above) from the OrderDate field... I have tried all that I could think of but nothing works. The last and the best try that I gave was the {B}following[/B] but that too does not work. Can you PLEASE help. Many thanks in advance:


Insert ORDERS
(OrderDateONLY, OrderDayName, OrderMonth, OrderDayOfMonth, OrderWeekofYear)
select
d, datename (dw, d), datename (mm, d), Year (d), datepart (ww, d)
from
(select convert (char (8), OrderDate, 112)as d
from ORDERS
) as x
