Total after each 25 records

Dear Metallica,

I would write the query that also returns a total of some columns after each 25 records.
Like this

CCNGO salary
1 5000
2 10000
----------------------
-----------------------
25 80000
Total < above 25 total >
26 25000
27 10000
---------------------
--------------------
50 13000
Total < total over 50 >


can achieve us


Waiting for response.

select 5 ccno,500 salary from dual union all

select 7 ccno,700 salary from dual
)--end of test data
,
intermd as (
select t.*,floor((row_number() over (order by t.ccno)-1)/3--here to change
)+1 rnum,row_number() over (order by t.ccno) rnum1 from tab t
),
intermd1 as (
select nvl(to_char(ccno),'total') ccno,max(rnum) rnum,sum(salary) salary,decode(ccno,null,max(rnum1)+1,max(rnum1)) rnum1 from intermd  group by grouping sets(ccno,rnum)
)
select ccno,case when ccno='total' then sum(decode(ccno,'total',salary,0)) over (order by rnum,rnum1) else salary end salary from intermd1 order by rnum,rnum1

because it is confusing if I calculate after 25 records (as I got less data), in this example I you shown after 3 drives...
Simply change the number to the observation within the query to 25, after taking this request to give the sum accumulated after each 25 records.

  • delay after each image record

    Hello

    Can someone help me please about an issue I'm facing. Basically, I managed to save five images in a directory, I now want to do is to save each image after a specific time period without interrupting the entire program. I tried to do this with the time elapsed time vi (under the calendar), but do not have to work. I know that it is possible using this vi. I think I have what I do is not the right way. Attached is a screenshot and the vi I haaving problems.

    Is that what you want? When you click on the button 'Save 5 images' type of lock, the VI is expected to produce 5 images, with a 3 second delay between them.

    Edit: this VI will also wait 3 seconds before you save the first file, if you want the first file to be created when the button is clicked, you must change the VI a little, so you can practice a little more

    Edit2: important to stress, that you didn't have any time in your loop to slow it down. If you run these timing loop, your computer tries to run it as soon as possible. This is not a good practice. So I put a wait 50 MS in the loop to be ok with this...

    Edit3: I also forgot to connect the cable to your digital indicator "picture #". You can put in the required place and connect the entire meter wire.

  • Favorites gets duplicated, rearranged, deleted, moved, or all the above after each cold start PC.

    Since the 26/08/12 in the bookmarks to a folder and subfolders either disappeared, were reorganized in other folders or "Unsorted Bookmarks", duplicate, 'old' old records of Netscape appeared in more recent cases of Mozilla, the bookmarks and folders were duplicated, but bookmarks in them were either older of the last (see Netscape) or have been removed or foregoing. The last folder of Netscape (version 8) and the Mozilla one have reversed positions, (the latter used as superior to Netscape one). This happens after each cold start PC. After several attempts of troubleshooting, it happens now in all folders. I save the bookmarks in a folder in My Documents separated as regular backups that seem to all be corrupted in the same way. I even purge the SYNCHRONIZED data and who has done nothing to solve this problem. I deleted the old bookmarks for Netscape 6/7 and the problem persists. Removal of duplicates is worse. Maintenance of places add worked only 2 consecutive days; Therefore, it is more effective. I have to restore the backup that I did whenever I use Fire Fox after a cold start.

    Have you checked all the backups JSON (10) in the folder bookmarkbackups to see if there are still no corrupted bookmarks?

    If all of your bookmark backups are damaged, you must first repair in a pure and uncorrupted places.sqlite file or try to do that via a tag HTML the backup is an appropriate HTML editor.

    If corruption always occurs after the computer starts and some security software is the most likely cause for this.

    You have not answered what firewall and antivirus that you use.

    Some security software has virtualization or sandbox features that can cause problems to protect and restore files in the Firefox profile folder.

  • Create a Windows 7 user profile which resets after each reboot.

    I want to configure a limited in Windows 7 user profile that performs the following steps after EACH restart or disconnection:

    • Reset the background / theme
    • Reset the desktop icons / shortcuts
    • Network mapped reset drives
    • Reset saved passwords
    • Delete the data stored since the last session
    • Remove newly installed applications / block the installation of the application
    • Reset the print queue to empty - if it was not already
    • Reset the default printer
    • Reset the homepage Internet Explore & settings
    • Reset the screen resolution

    The idea is to create a profile for workstations in an office of the admin who works a bit like an internet café. They have a couple of shared workstations, a network printer, and they store the data on a file server and work on a local application server.

    The current problem is that they constantly record their passwords, remove network drives and change the General configuration of work stations (by chance), which makes it difficult for other users to work - that they do not recognize the look & feel and now don't know where to do what.

    I want to create a 'shared' user profile where they can log on, and everything looks familiar. All settings are saved as defaults and no matter what you do, as soon as you log out or restart, the parameters of return by default.

    I would appreciate help.

    Here are a few options:

    • Windows steady state (http://www.microsoft.com/windows/products/winfamily/sharedaccess/default.mspx). The product is supported for Windows XP and Vista, but maybe it works for Windows 7 too. Or maybe there is an equivalent Windows 7 somewhere.

      Note this:
      -Before starting, you must use the robocopy command in reverse so that it fills the C:\Users\UserName.bak folder.
      -The task must be run under the system account.
      -The task will run with the highest privileges.

  • How can I make all my actions run automatically, without dialog boxes that appears after each step?

    My question is in what regards Actions. I have my Options of accelerated reading the value, and I unchecked the option 'Allow Recording tool', but every time I run a certain set of actions, a dialog box is displayed for each step and I have to press return to continue after each step. In my mind, which reduces the value of action in the first place. Any ideas on how to solve this problem? Thank you very much!

    In the control panel actions are two boxes next to each action. The first is a check mark and the second looks like one of three things: a red box, a gray or an empty box. If they red or grey area is there then the dialog boxes will be displayed. Turning point of this area on 'stop' should fix your problem.

  • Police have a capital 'A' with a carat on top after each period and 2 spaces. How can I fix it?

    Sometimes, I get this when I get emails. If I send an email and then go to the folder "sent" to see what I sent, there is a capital A with a carat on top after each sentence (but it seems that when I finished the sentence with a period and 2 spaces.)

    I tried to change the fonts, but that doesn't seem to help.

    Looks like the incorrect character encoding is used.

    What character encoding you have set here:
    Edit > Preferences > display > formatting tab
    Click on the button "Advanced".

    See my example below image

    You can edit an image showing what you have selected, is much easier to type this.

    What is only a problem with mail in the "sent" folder or also with mail in other folders?

    Select the e-mail in the "sent" folder
    Click on "other actions" > view source
    or view > message source
    or
    CTRL + U

    What is in the source code for these lines:
    example:
    Content-Type: text/html; charset = windows-1252
    Content-Transfer-Encoding: 8 bit

    You can try to select email then:
    View > character encoding
    What is selected?
    Try another encoding, note that this will be only temporary while e-mail.

  • How to stop automatic download after each time that you buy a property?

    I would like to know if there is a way to stop an application being downloaded automatically after each purchase?

    Welcome to Apple Support communities

    If I'm not wrong, you want to disable automatic downloads (the feature that automatically downloads all content you purchase all your devices), right? If this is the case, there are different ways to disable depending on the device that you are using:

    • For iOS: go to settings-> iTunes and App Store (or App Store), then disable everything under "automatic downloads.
    • For PC and Mac: open iTunes, go to Preferences (in the iTunes menu on a Mac) or edit on a PC-> Store menu and disable everything under "automatic downloads.

  • El Capitan 10.11.2 disconnects from the network of Canon printer macbook pro after each use but with the same OS version iMac remains connected

    How to prevent my Macbook Pro El Capitan 10.11.2 going to disconnect my network printer Canon?   My iMac running the same OS version don't unplug and behaves like any normal wireless connection.  I deleted the printer and added back, reset printing, etc. nothing works.  Given that the Mac is 6 "each other and 5 feet of printer during the last test, it must be something specific to the Macbook.  The Macbook identifies the printer after each reboot the printer as printer Canon right, but once the task is completed does not have the printer.  Everything is on the same wireless network. Computer Windows also recognizes the printer and it keeps alive after printing.

    Please read this message before doing anything.

    This procedure is a diagnostic test. It is unlikely to solve your problem. Don't be disappointed when you find that nothing has changed after you complete it.

    The test is intended to determine if the problem is caused by a third-party software that loads automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.

    Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.

    Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.

    Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

    The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

    Test in safe mode. Same problem?

    After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of the test.

  • HP Envy 120 printer prints OK but the error message after each document

    After upgrading the firmware in my printer, I now get a window pop up with the title, "Unable to communicate with printer" at the end of each document.  The error message should be cleared before the next document in the queue will print.  Each document prints correctly despite the error message.

    Another thing that may cause this condition besides the update of the firmware is this: I have set up my printer for wireless printing, which worked OK.  However, I am currently using the printer with a wired USB connection.  Of course, the version non-reseau of the printer is selected as my printer 'default' regarding this error report.  The update of the firmware was held at the same time that change this "setup".

    Hey @rrbNevada,

    Welcome to the Forums of HP Support!

    I understand that your printer HP Envy 120 seems to have an error "Unable to communicate with the printer" after each print job is printed and this problem seems to have started after an update of the firmware running and change your connection type. Maybe it's a coincidence.

    For me to help you I need to know what operating system you print since?

    What is my OS?

    For now, I would like to run the print tool HP and doctor Scan. It is a practical tool that will 'fix print' questions automatically for you. It will scan the computer for any conflict of driver printer HP, connection problems and other issues that can cause problems with your printer. It will also try to fix these problems for you.

    HP Print and Scan Doctor

    If printing HP and doctor Scan fails to solve your problem, I recommend a complete uninstall and reinstall of your software and drivers for a clean slate to work with.

    Uninstalling the printer software

    After you have uninstalled the drivers and the printer software I need you to reinstall. To reinstall, I add two documents of reference below:

    Installation for USB under Mac OS X

    Installation of USB on Windows

    Because you use the printer for network and USB connections on your computer I suggest you first run installation from USB.

    Once the printer is installed for USB, then you can add in the wireless version.

    Adding a printer wireless on Windows:

    1. open the Printer Assistant software on your desktop. It should resemble a black printer icon and has your options of Scan inside.

    2. click on the 'utility' on the top tab

    3. click on 'software and configuration of the printer.

    4 enforce "connect a new device" for the network connection.

    This will add two copies of your printer and both will be implemented properly for scanning and printing.

    Adding a printer wireless on Mac:

    1. Click The HP utility icon in the Dock.

  • How to display data series changed after each step in labview gui, that is to say after the match point fantasy, after substring etc.

    Hi, I have a labview GUI that receives data serially through VISA and basically chops to the strings and realize games until I have values that I'm looking for. I have then convert Ascii string in decimal and feed the new values to a waveform. However, I discovered that some of the output values are incorrect. I checked this by pulling data through Realterm.

    Is it possible that I can see the modified data after each step in the user interface so that I can find where the problem is? I created indicators after each step, but they do not display data, I guess that its because the data is moving too quickly.

    I am very new to labview and struggled through every bit of this GUI, as none of you regular posters know. If you can suggest a solution, please know that I will probably ask more fundamental questions in order to implement your solution.

    I enclose my GUI with a screenshot of the same data through the Realterm. Basically any where you see xxxx TR TR or W xxxxW, know that it is the data between them is to say xxxx that corresponds to the data of interest. Everything else is ignored.

    I suspect that the problem lies in the string to decimal conversion and where 3 digit values increase to 4-digit values. That is, all values of less than 850 are correct but it is the maximum value is reached. My values are expected to reach 2500. Any help would be greatly appreciated.

    You have other debugging tools available to you.  You can use the run culminating to slow down the code and show you the data flowing from each wire.

    You can create a Subvi, which takes the data of each wire and written to a log file if you can review it later.

  • I would like to do something after each subsequence complete execution. Y at - he recalls of any engine?

    After each completed sequence execution to a file of the client's sequence, I would like to check the status of each step in that order. Based on the Statute, I want to do something. Currently, I have a sous-suite that is called at the end of each sequence. I was wondering if I could move this sous-suite in some reminders so that I should not call explicitly in each sequence.

    Saravisu,

    There is a way, using the SequenceFilePostStep callback. This run for each step, but you can use an 'If' flow control check for PropertyExists ("Parameters.Result.TS.SequenceCall"); set to true, the results of the appeal of the sequence will be in Parameters.Result.TS.SequenceCall.ResultList.

    Note This will run only for the steps that occur in the sequence file that contains the callback to SequenceFilePostStep.

  • Value of updating after each sequence of dish

    Hello

    I'm doing a labview program analysis principal components. My program works well, but since it is tons of calculation it takes too long and there is no way of knowing if all the steps is going well. I'm putting some kind of progress is in my front panel that tell me what stage of the program. The vi for progress bar I found works well with the loop 'for', but I don't have a lot of loop and but I have my program have step 6 and I used the flat sequence for each step. Is there a way to update the value of slide after each sequence of dish. I'm using Labview 8.2 and I have attached a picture of a vi model which has a blade and has four sequences flat and each sequence a 1 second delay. I want the value of slide to day as the first dish to pass to other sequence data.

    Thanks in advance
