Having trouble wrapping query as subquery in order to sum a column

I have a query whose first column in the "select" is something like "count(distinct t.id)", and the query has a "group by" for several columns.
This generates a number of rows with a number in the first column representing the number of distinct id values in the resulting group, and several other columns.
I need to create a modified query that produces the sum of that first column.
I figured this would look something like:
select sum(total) from (select count(distinct t.id) as "total", ... from ... ... where)
I'm not able to get this to work. It appears I can't refer to the alias from the parent query, but I've tried other ways of referencing that column value, and I just can't figure it out.
I'd prefer not to have to provide the original query here. I'm hoping that I've provided enough information that someone could use to give me a useful response.

Having trouble with query

I am trying to query for a report to list aircraft by manufacturer, model name, aircraft number, destinations flown, miler per charter and the total revenue per charter, as well as total amount of revenue generated and total number of mile flown for each aircraft. This is what I have so far, I keep getting stumped when I try to sum I get error that certain lines is not single-group group function.
-----DATA

test@ORA10G>Notes:
(1) Lines 29 and 30 (in bold) show that '4278Y', which corresponds to mod_code = 3 i.e. "Piper Navajo Chieftain", flew to ATL twice traveling 10 and 20 miles respectively.
(2) The last line of the resultset (in bold) shows the total miles for "Piper Navajo Chieftain" i.e. 35 miles.
The trip charge, consequently, is 35 miles * 0.3 * 0.035 = 0.3675
where 0.3 is the mod_chg_mile for "Piper Navajo Chieftain".
(3) Note the change in the columns that constitute the GROUP BY clause. What it does is - for every combination of:
 (i) m.mod_manufacturer
 (ii) m.mod_name
 (iii) a.ac_number
 (iv) c.destinationit sums up the c.char_distance and multiplies it with the product of m.mod_chg_mile and 0.035.
(4) Also note that you can use aggregate functions (sum, in this case) more than once in the SELECT <column_list> part of the query. You need to include the rest of the columns (the 4 above) in the GROUP BY clause.
Hope that helps.

I am having trouble with my bookmark bar changing order between my devices. I have them organized for convenience, but when I arrange them on one device they change on the others to a different order. how can I fix this?

I have 2 desktops and a laptops connected by Firefox sync which I set up at some time during the beta. I have several folders, dividers, and bookmarks on the toolbar which I try to keep organized based on their use (web design, hardware/tech support sites, personal, etc) but when I arrange them on one computer it screws them up on the others. I would like for it either to keep them in the same order on all machines, or at least have to arrange them on each machine separately without them affecting the other so they stay where I put them. Does anyone know how I can accomplish this?

This is what I'd suggest get your machines matched. Sync your machines so all data is on both. Then pick one to get all of your organizing as you want it. (or do this before you even setup sync) Then, when you do your initial sync from that organized machine, select: replace all other devices with this computers data. (you can also do that as Manage Account > reset sync.
After that, changes in order on one machine should be reflected on the other. Remember though Sync '''merges ''' the data from your machines. If you work on two machines side by side and make order changes on both without syncing either, once you do sync, Sync will have to again figure out how to merge the incongruities, which may not be what you expect.. Be careful, if order is important to you.

So to clairfy:
In the example above: team_id = 235 (Oakland) qualifies under the scope I've described. They won a four game series (game codes: 733814,733815,     733838, 733839), with the forth and final game being a 'W' (Win) on the road.
Four Game Series: Four consecuitive game dates where the same two teams play against each other.
The four game series including game_codes (733665,733666,733667,733813) doesn't qualify under the scope because the forth and final game of the four game series wasn't won at home.
So I have two issues,
1)I'm having trouble finding code to determine a four game series. In plain english it would be, where the same two team_id's play against each other for four consecutive game_dates), I'm having trouble translating that into sql code.
2) After I figure how to return a four game series, how to code: where the team 'W' (won) all four games in the four game series.
Please Note:
- Those are the only columns availble to figure out the scope i've described above
- The data I've provided is merely sample data that is convienent in showing what I'm trying to accomplish, the actual table clearly doesn't contain this convienent of data.

Hi,
We want to count the number of times where
(a) the away team won
(b) the same team won the last 3 games against the same oponent
The WHERE clause condition for (a) is: "away_outcome = 'W'
The WHERE clause condition for (b) is somewhat more complicated.
{code}
WITH     got_cnt     AS
     SELECT     away_outcome
     ,     COUNT ( DISTINCT
               CASE
                    WHEN home_outcome = 'W'
                    THEN home_team_id
                    ELSE away_tem_id
               END
          ) OVER ( PARTITION BY LEAST (home_team_id, away_team_id)
               ,     GREATEST (home_team_id, away_team_id)
               ORDER BY     game_date
               ROWS BETWEEN 3 PRECEDING
                    AND     CURRENT ROW
               ) AS cnt
     FROM     cs.tm_data
SELECT     COUNT (*)
FROM     got_cnt
WHERE     away_outcome     = 'W'
AND     cnt          = 1
{code}
First of all, how do we know which team wom any game?
{code}
CASE
     WHEN home_outcome = 'W'
     THEN home_team_id
     ELSE away_tem_id
END
{code}
How do we know if the same team won the last three games against the same oponent?
This just reeks of analytics: we need to partition by the pair of teams who played, sort by date, look at the window consiting of the last four games, and see if there was only won distinct winner in that window. I called this count cnt in the query above.
The tricky part of this is how to partition by pairs. Since they have unique ids, we can sort their ids and PARTITION BY x, y, where x is the lower one and y is the higher one.
Since this cnt is to be calculated by an analytic function and then used in a WHERE clause, it must be computed in a sub-query.
If you'd post the CREATE TABLE ... and INSERT statements for the sample data, as Centinul said, then I could test this.
Edited by: Frank Kulash on Jun 6, 2009 5:48 AM
The query above needs an additional check that there have been at least four games between these two teams.
One way to do this would be to repeat the analytic COUNT, but without DISTINCT, and check that it returned 4. ROW_NUMBER would be a shorter alternative.
Either way, the new analytic function would need the same CASE, GREATEST and LEAST calculations, so I would add another sub-query to calculate those values once.

News for Users having trouble ordering books

I was having trouble like many others ordering books during the last 2 weeks. I was also concerned about pending charges on my bank account. I received a very detailed explanation and helpful suggestions today form Apple Support. I am posting this in hopes that it helps others and ends all the frustration.
My name is Patrick and I'll be assisting you.
I understand that you're having an issue placing a book order. I also understand that there were charges on your credit card statement that were eventually dropped.
I reviewed the orders you submitted for the book titled "Honeymoon" and found that the file could not be opened. That is why your orders haven't processed completely. The size of the book shouldn't be an issue, so you don't need to change anything in it. Please keep submitting the order until you're successful. You may want to try during non peak hours so there'll be less traffic on your ISP's network.
As for the multiple charges, when you make a purchase using iPhoto, Apple sends an authorization request to your credit card company for the approximate amount of the purchase. This is to verify that your account has sufficient credit to cover the amount of sale. It is a temporary authorization hold, not an actual charge. Most credit card companies remove authorization holds within 48 hours.
Please note that even an unsuccessful attempt to purchase an item may cause an authorization hold, depending upon how much of the transaction was completed, and multiple attempts can cause multiple authorization holds.
If you have any questions about whether an amount found on your online statement is an authorization request or a charge, or when the authorization hold will be removed from your account, please contact your credit card company or financial institution.
To view your purchase history, visit http://www.apple.com/internetservices/yourorderstatus and sign in using your Apple ID and password.
I hope this clears things up for you. Please accept my apologies for any frustration this has caused you. I want your experience with us to be the best possible. Have a pleasant day.

It's really hard to say without seeing the form, and ideally being at the machine that it doesn't work with. I'd be happy to take a look at the form if you're free to send it to me: acroscript at gmail dot com

Having trouble with order

Is anyone but me having trouble getting a new iphone? My daughter and I ordered them on the 9th, had them canceled by apple on the 17th. We reordered them and I can tell that by tomorrow apple is about to cancel them again. My order status went from prepared to ship to not yet shipped today. I spent 4 hrs on the the phone between apple and ATT today about this. Each one blames the other. I have talked to so many people I have a headache, and am ready to throw my iphone at someones head. We both have the original iphone so we are ready to upgrade, but now we are bith so frustrated that I am ready to leave ATT and forget the whole thing.

On your first cancellation email, did it say that it was cancelled because it couldn't get an approval from ATT? if so, try calling ATT to see why it's not approved. I had similar issue where I accidentally placed 2 orders and one number can only buy one phone.

I would like to print a four sided programme, but am having trouble finding out how to organise the sections onto a 17 by 11 paper with the sections in the right order. Any help?

If all you are going to do is print double sided and them make
a single fold reducing the page to 8 1/2 x 11, one side of the
original 17 x 11 page will be page 4 on the left as you hold
the page facing you and page 1 on the right, reverse side
should be printed so top is same as top on the the first side
and will be page 2 to the left and page 3 to the right. Pick
up the double sided document with pages 2 and 3 facing you, fold
left edge to meet right edge; you should now have fold on the left
with page 1 facing up toward you, turn the page as you normally
would and pages 2 & 3 should be in order, and one more turn brings
you to page 4 and the fold should know be on the right. I hope this
explains clearly enough - if not, post back and some one should
join in with a better explanation.

I am having trouble uploading anAperture photographic book to Apple. The first time I tried “Buy Book” theorder proceeded normally but when it came to uploading the book to Apple it"uploaded" for six hours without going through so I aborted theattempt and cancelled the order.
The second time I tried the samething happened so after nine hours I found that the "Quit Aperture"button had greyed out so I had to Force Quit. I do not know if the order wascancelled but I do not think that the upload was successful.
What can I do about this problem?

I also am not able to print a book. I have Aperture on two Mac, MacBook Pro (current) and a MacPro - both printed books prior to update 3.1.3 now all I get is the spinning ball then I have to Force Quit. I tried books I have ordered in the past (trying to print a new book) and they also failed. This is not a picture problem but a problem with 3.1.3 update. I would like to print some more books and give Apple some money but can't.
Any suggestions?

I've done a separate search and found that other users are affected, but there doesn't seem to be a clear-cut solution ... (Norton, McAfee and Kaspersky don't seem to be able to detect/fix it).
I'd like to continue using the Firefox/Google combination (nb: the hijack virus also affects IE but not Safari) - do you have a patch/fix that could rectify the vulnerability in your software?
thanks

''' "... vulnerability in your software?" ''' 
And it affects IE, too? Ya probably picked up some malware and you blame it on Firefox.
Install, update, and run these programs in this order. They are listed in order of efficacy. '''''(Not all programs detect the same Malware, so you may need to run them all to solve your problem.)''''' These programs are all free for personal use, but some have limited functionality in the "free mode" - but those are features you really don't need to find and remove the problem that you have. 
''Note: If your Malware infection is bad enough and you are mis-directed to URL's other than what is posted, you may have to use a different PC to download these programs and use a USB stick to transfer them to the afflicted PC.''
