How to Compute the average six months of customer orders excluding the first orders

Hi all
I am writing some basic sql to generate some measures from a postgres database table that are going to be inserted into a SQL SErver table.
I have to two tasks where I am supposed to generate the average 6 months spend and average 1 year spend using the customer data but excluding the first time orders.
I have some sample data below:
CREATE TABLE orders
persistent_key_str character varying,
ord_id character varying(50),
ord_submitted_date date,
item_sku_id character varying(50),
item_extended_actual_price_amt numeric(18,2)
INSERT INTO orders VALUES ('01120736182','ORD6266073','2010-12-08','100856-01',39.90);

INSERT into orders values('01002319116','P00532470001','2010-05-04','HO 100482',49.99);
Using the data, this is what I have done:
SELECT q.ord_year, avg( item_extended_actual_price_amt )
FROM (
SELECT EXTRACT(YEAR FROM ord_submitted_date) as ord_year, persistent_key_str,
min(ord_submitted_date) as first_order_date
FROM ORDERS
GROUP BY ord_year, persistent_key_str
) q
JOIN ORDERS o
ON q.persistent_key_str = o.persistent_key_str and
q.ord_year = EXTRACT (year from o.ord_submitted_date) and
o.ord_submitted_date > q.first_order_date AND o.ord_submitted_date < q.first_order_date + INTERVAL ' 6 months'
GROUP BY q.ord_year
ORDER BY q.ord_year
Can someone help me look into my query and see whether I am doing it the right way.
Thanks,
Ion

How to get the first day in the month from a domain date ?

Hi,
I like to know how to get the first day in the month from a domain date?
Thanks
Stephen

Hi Gokul...
Instead of using the funtion module you can just write the 3 statements of code to get the first day of the week.
Its similar to the above one but instead of writing case statement you can achive the following.
data : w_res type i,
w_data type d,
w_res = w_date mod 7.
w_date = w_date - w_res.
write w_date.
This works.
Regards,
Siddarth

How to Capitalize the first letter or an entire word using a shortcut on the keyboard just like in microsoft that uses shift+F3

please how can one How to Capitalize the first letter or an entire word using a shortcut on the keyboard just like in microsoft that uses shift+F3

What do you mean there was "no effect?" I'm not aware of any effects.
It looks like that Service is also in the App Store. From their screen shots, the services are prefaced with WordService:
You can see an example in the App Store for their app: App Store
After installing, you should now have those text services in your Services menu. You can then add shortcuts in the Keyboard System Prefs.
Most Apple apps have a Transformations menu in the Edit menu. You can Make upper, lower, and Initial caps with those. I would stick with Word Services, but you can make Application Shortcuts for the items in the Transformations menu.
Again, in Keyboard System Prefs, Under Applications, Click the Add button on the right side pane.
Set it for All Applications
Enter the menu command exactly as they appear in the Transformation menu (separate entries for each),
Make Upper Case
Make Lower Case
Capitalize
Give them a shortcut.

something to look forward to then, because we get used not to use our shift button any more, since iPhone and iPad do it for us. entourage and other ms stuff do it. pages does it too now (put it on in the auto-correct in preferences). bizarre however some loose the capitalization when you copy the text. pages to stickies or mail does not. that's good !

How to include the first row of detail in every xquery transformed xml?

I am dealing with a XML file,where i need to publish to different BS.
First node will be a common node node which contains vital info,second node goes to one BS and third goes to another BS.
*<header></header>*
*<details></details> (they are unbounded, but the first detail tag which comes in the input file is a mandatory tag in such a way that it needs to be included in every transformed message)*
*<trailer></trailer>*
We need to apply x query transformation on it in such a way:
*</header></header>*
*<1st detail></1st detail>*
*<detail></detail> (2nd row of detail in input file)* -------------------------> Goes to BS1
*<trailer></trailer>..*
*<header></header>*
*<1st detail></1st detail>*
*<detail></detail> (3rd row of detail in input file)* ----------------------------->Goes to BS2
*<trailer></trailer>*..
And so on.
Now, the problem is how to include the first row( *1st detail* ) of detail in every xquery transformed xml?

are you looping of this input with a for each?
/yourdata/details[1] should return always the first detail element.
or before the for each do an assing of this first detail element to "generic_details_var"
and use this var in every looping iteration (in an assign or as input for xquery)

How to echo the first line???

Hi everybody,
I need to know how to echo the first line of an XML document with a SAX parser, for example :

        System.out.println("Data = (" + data + ")");
    }but it doesn't work.
Please, help me...

Windows Explorer - How to select the first item once we open the explorer?

Hi,
In Windows Explorer - How to select the first item once we open the explorer using keyboard shortcut. I typically use downward arrow, it goes to the 2nd item in the list, then I again have to use upward arrow to go up.
Is there a shortcut to select the first item in the list using keyboard? This is not specific to Windows 7, it has been the behavior even in previous Windows OS versions.
Thanks,
Mallik

Opening a Microsoft Ticket is probably your best option. Unfortunately the change will not happen immediately and it will require multiple users to send in a ticket. I hope this ends up being resolved though.
Good luck Mallik

How to select the first record?

A00000001 2001/02/02 AA
A00000002 2001/03/01 AC
A00000002 2001/05/07 AC
A00000003 2001/03/05 DD
result:
A00000001 2001/01/01 AA
A00000002 2001/03/01 AC
A00000003 2001/03/05 DD
Thanks

Vincent,
You could do it as Carl suggested, with a couple of
corrections. You would need to include the CustomNo column in
the order by clause of your cursor. You would also need to add
a where clause to your update statement, otherwise everywhere
Region in the table would be updated with the same value of the
last CustomNo in the cursor, regardless of the CustomNo in the
table. See corrected code below:
DECLARE
CURSOR     cust
IS
SELECT     DISTINCT CustomNo, Region, Purchase_Date
FROM       my_table
ORDER BY   CustomNo, Purchase_Date, Region;
c_customer VARCHAR2 (9) := '...';
c_region   VARCHAR2 (2) := '..';
cntr       NUMBER := 0;
BEGIN
FOR x IN cust
LOOP
    IF x.CustomNo != c_customer
    THEN
      c_customer := x.CustomNo;
      c_region := x.Region;
    ELSE
      UPDATE my_table
      SET    Region = c_region
      WHERE CustomNo = c_customer;
      cntr := cntr + 1;
      IF cntr = 25
      THEN
        COMMIT;
        cntr := 0;
      END IF;
    END IF;
END LOOP;
COMMIT;
EXCEPTION
WHEN OTHERS THEN
    NULL;
END;
Another option is that you could just use one update statement,
like this:
UPDATE my_table a
SET    Region =
       (SELECT DISTINCT Region
        FROM   my_table b
        WHERE (CustomNo, Purchase_Date) IN
               (SELECT   CustomNo, MIN (Purchase_Date)
                FROM     my_table
                GROUP BY CustomNo)
        AND    a.CustomNo = b.CustomNo)
