You can use the COUNT aggregate function.

SELECT count(*) FROM  WHERE dept_name = 'Homeopathy'

    I would like to know who among these numbers have occurred and how many times. For example (just to have as an example): number 10 repetitions 5 times, number 13 repeated 3 times, 24 repetitions 9 times.

    Repeats = duplicates.

    I want to know all the repetitive number and how many times they repeat.

    Is there some kind of formula I can use to get there. It would be good to have the sorted result. For example:

    32 repeats 10 times

    24 repeat 9 times

    6 reps 8 times

    5 repeat 7 times

    22. repeat 6 times

    10 repeats 5 times and so on.

    Hello

    Problem of three steps:

    1. Determine the distinct values
    2. Count the number of times each appears in the table
    3. Sort by value or frequency (or both).

    The first step is easily handled by copy separate Automator Service, a Service of Automator, written by SGIII. A link to the file in post June 21 of the SG in this thread: Re: Analyzing column (maybe not the correct wording)

    After downloading and installing the service, select the cells containing the numbers, call the service, and then select the first regular (ie. non-header) cell to a new table and the dough.

    (The following assumes the new table has a header row, no column header, and you have selected - click - cell A2 before pasting.)

    You will get a list of distinct numbers in a single column (A2 - A34, of your sample and support of note).

    To count the numbers:

    In this example, the existing table is named 'Table 1'

    Enter the following formula in B2 the new table, and then fill up to the last line of the column B:

    = COUNTIF (Table 1::B:G, A)

    Results should be as shown:

    Sort the results on column (value) or B (frequency)

    Two types (A, then B) will be put in order of frequency, with values appear the same number of times sorted by value within this group.

  • I used 'Customize Firefox' to change toolbars show, and now the Firefox Customize, tab keeps appearing no matter how many times I close.

    The window customize Firefox and tab guard popping open at seemingly random times. This continues to be no matter how many times I close.

    One possible reason is that if it was added as a second 'Home tab' in which case it will be displayed in each new window (Ctrl + n) and every time that you click the Home button.

    To verify that you can use the page Options, as described in this article: start-up, homepage, tabs and download settings.

    Look for a vertical bar character at the heart of the area that separates the two addresses. A simple example with short URLS:

    https://www.mozilla.org/|about:customizing
    

    The bar certainly can be hard to spot with long URLs, but when you find it, delete everything to the right of the bar, then the bar itself (I suggest to remove the last bar so things don't accidentally get it together).

    Apple Photo 1.3 serious problems - how can I SOLVE all these problems?

    (1) breaks down without rhyme or reason no matter where I am in the workflow.

    (2) pictures will not be Shut Down Every Time, even after several days of waiting.

    (3) aPhoto frequently badly chooses picture in the EDIT picture option, I get a picture different than the one I clicked on which is on a 100 pictures in a row.

    (4) picture constantly order of photos in a slideshow changes no matter how many times the movements of the end user the photo back to the good look at an order. Example: Bathroom Plans eventually grouped with pictures of kitchen! I have found no way to stop this weird behavior! Is there a way to stop this? If I drag the photo again some 7 additional photos in the slide show, after a minute or less, he appears again to where it was it not. !@#$%$#

    (5) If you make any CHANGES to a photo, it often changes the appearance of your complete slideshow of this picture with impatience. So you lose all this not work fix your configuration of the slide show. Even changing the order of photos once more that I had put back where they should be. !@#$$#@

    (6) photo identifies often shades of lamps and long door handles as the faces of the people.

    (7) photo made bad decisions when it comes to brightness, contrast and colors effortlessly around other than to use other software, where as with iPhoto there was a lot of workarounds. I could continue, but will save one who might be reading of this.

    I am up to date on all updates for my Mac. If anyone have REAL answers so please spilling the beans, but according to me, it's the only truth is that Apple has rolled out a product inferrer to replace an exceptional product, called iPhoto, which does not work on my new iMac computer 5K of 27 ".   If I knew what I would have chosen another computer that I use iPhoto to prepare more of fifty to sixty thousand photos in a given year and I use iPhoto to make hundreds of slideshows from it.  Are there plugins for Photo 1.3? I ask because I see where there could be Add-ons, but I can't find.

    Apple has taken a serious decision by turning his back to iPhoto and tens of millions of loyal users.

    Thanks in advance to anyone brave enough to tackle this job.

    First, back up your library of Photos and hold down the command and option keys while launching Photos - repair your database - you have a corrupted database

  • How many times the files are saved automatically and how to clear the backup?

    The properties of a folder in the Windows 7 system, you can retrieve files stored once even if they have been removed.

    How many times are the files saved in this way automatically?
    Files including files get saved in this way?
    How long they stay in the system?
    How can we make them disappear in order to reclaim space?

    Because I am doing a complete disk image automated nightly, I did not invoke the 'previous version' feature of Windows 7 and therefore do not know many details about it.

    These web pages are substantially the same as the help files for support &, but maybe add a little:
    http://Windows.Microsoft.com/en-us/Windows-Vista/previous-versions-of-files-frequently-asked-questions
    http://Windows.Microsoft.com/en-us/Windows7/recover-lost-or-deleted-files

    'Previous versions' applies to both files and folders.  I haven't experienced it, but likely restore a previous version of a file would restore files that have been deleted from this folder since the creation of the earlier version.

    Under Windows 7, restore points are created automatically each week (on XP, it was once / day) and just before significant system events, such as the installation of a program or device driver. You can also create a manually restore point.  In practice, you will find a lot more than one restore points / week.  For example, my Win 7 Pro box displays the restore points following last week:
    Automatic restore point 3/17
    Update of windows of 3/16
    Update of windows of 3/16
    Windows 3/12 update
    Installed software 3/11
    USB device driver installed 3/11
    Automatic restore point 3/10

    It is not clear to me how to change the frequency of the automatic system restore points in Windows 7. If seen sites which proposes to change the frequency of a scheduled task in the Task Scheduler - but the settings in my task scheduler to launch SR once / day and as seen above, which does NOT result in a daily automatic Restore Point. I saw references to editing a registry value, but it was not definite either.

    To remove "Previous Versions"-

    • Click on the start Orb, then right click on "Computer", then select Properties (Alternatively, control panel > system)
    • Click on the "System Protection" link in the left pane
    • Click on the tab 'System Protection '.
    • Click on the button "configure."
    • Select the option "Turn off system protection" or click on the button 'delete '.
    • OK your way out

  • How many times is the locks on files updated (VMFS/NFS)?

    If I understand correctly the ESXi host that is running a certain VM which has its files residing on shared storage must update the regularly filelock to show that he is alive and that he still owns the file. And if the host should fail filelock updates should stop appearing, which means that another host can start the virtual machine by using HA for example.

    So my question is, how many times is that these locks to update the file? And is there a difference between VMFS and NFS in this case? (Also NFS using *.lck files to save the lock state, but the time interval).

    From the top of my head, it's 15 seconds until the lock is declared dead and released. Indeed, this could be a race condition as HA will restart the virtual machines on the 16th second. Don't get me wrong, it is designed in such a way that it will work, but I still generally recommend increasing the das.failuredetectiontime.

    Also, I think the locking area is updated about every 3 seconds.

  • How many times should I stop my MacBook Air

    I have a MacBook Air (early 2014), with a processor i5 and 4 GB of RAM. It will be 2 years from November 2016. Summer's going hard for me for a while now and works very well without any problems. I use applications like Final Cut, Motion 5 and Xcode and I am satisfied with the performance of such a light machine.

    Apart from the information on my Mac, I have a question about proper use to optimize the performance and life of it. How many times have I stopped him? I use my Mac a day should I allow to sleep when I do not use as it has little effect on the battery and allows me to pick up where I left off. Should I only stopped when loading or is it okay to sleep by loading too? Should I stopped him every month or so or just during the software updates as I prefer to leave is majority of sleep of the time it won't have a long amount of time without me using it.

    Thank you.

  • How many times firefox automatically save the Favorites of the user?

    In the example given in the tutorial of Firefox, it would seem that Firefox performs an automatic backup of the Favorites of the user in a random manner, that is, sometimes daily and sometimes several days (weeks) pass without backup automatically bookmarks in Firefox. No one knows how many times we rely on Firefox by performing an automatic backup of bookmarks? I'm new to Firefox and want to know if I need to perform manual backups regular bookmarks for more safety in case of crash. Thank you!

    Firefox will create JSON backup each day you launch Firefox. If you keep your computer and do not close Firefox then it may not be a JSON backup created.

    If you close Firefox and no backup is created on the next start, then you can have an extension interference or other problems with your software folder or cleaning of profile (e.g. CCleaner) which removes backups.
