Return Dates Not in Table

Just wondering if anyone could help with returning dates not in a table eg
Orders table has a number of Orders with OrderDate stored. I would like to
write a query that displays all dates between say 01 October 2005 and 30
October 2005 that did not have a OrderDate, ie if there were no Orders with
an OrderDate recorded on the 5 October then the query would return 5 October.

Below is one way you could achieve this using a Calender Reference Table:
CREATE TABLE orders
(
OrderID INT,
OrderDate SMALLDATETIME
)
INSERT orders SELECT 1, '1 Oct 2005'
INSERT orders SELECT 2, '2 Oct 2005'
INSERT orders SELECT 3, '3 Oct 2005'
INSERT orders SELECT 4, '4 Oct 2005'
-- Create Calender Reference Table
CREATE TABLE calender
(
CalenderDate SMALLDATETIME
)
DECLARE @.dt SMALLDATETIME
SET @.dt = '1 Jan 2005'
WHILE @.dt < DATEADD(YEAR, 1, '1 Jan 2005')
BEGIN
INSERT calender SELECT @.dt
SET @.dt = DATEADD(DAY, 1, @.dt)
END
SELECT calenderdate
FROM Calender
WHERE calenderdate BETWEEN '1 Oct 2005' AND '31 Oct 2005'
AND NOT EXISTS (SELECT 1 FROM orders WHERE OrderDate = calenderdate)

retrieve only new customers with orders

I have a table with orders and customer info. I want to retrieve only customers with new orders only. These are the available fields: customer Id, Order Id, Order Date, and Order Subtotal. I need help with the "where" section of the query.

Hi Ray, this mainly depends on how you define "new" relative to the date values in your data. But assuming "new" means orders placed today, you could use something like "where datediff(dd,OrderDate,getdate()) = 0". You can review the SQL Server books online for more information about getdate(), datediff(), or the other date functions you could use here.

Thanks, Dean
