Find duplicate with sum=0

I need to find duplicates (ID) but the sum of column VALUES has tu be zero. can anyone help me please ?
I HAVE TABLE
ID VALUE
100 -100
100 100
100 100
200 50
--------------- THE DESIRED RESULT IS
ID VALUE
100 -100
100 100
------------

Sorry,
I only read you leading question:
I need to find duplicates (ID) but the sum of column VALUES has tu be zero(The obvious answer would be there isn't any)
Only now do I see your expected output.
You need to explain which row to eliminate and why, in order to go from
ID VALUE
100  -100
100   100
100   100To just:
ID VALUE
100  -100
100   100Also, what should happen if you have, say
ID VALUE
200   -50
200   -50
200   100Regards
Peter

  • How do I find duplicate photos in iPhoto

    I have so many duplicates in iPhoto that my library files is way too large by thousands of photos. I need to find a way to weed out duplicate photos. Anyone know how?
    Thanks,
    Barb

    Where are you seeing these duplicates?  If you're seeing them from withing the iPhoto window then you can use one of the apps listed below.
    If you're seeing those "duplicate" files via the Finder then you don't have duplicates.  iPhoto will have a minimum of 2 files in it's lbrary for each file imported.  So don't relay on what you see via the Finder regarding duplicates in the iPhoto library.

    hese applications will identify and help remove duplicate photos from an iPhoto Library:
    iPhoto Library Manager - $29.95
    Duplicate Annihilator - $7.95 - only app able to detect duplicate thumbnail files or faces files when an iPhoto 8 or earlier library has been imported into another.
    PhotoSweeper - $9.95 - This app can search by comparing the image's bitmaps or histograms thus finding duplicates with different file names and dates.
    DeCloner - $19.95 - can find duplicates in iPhoto Libraries or in folders on the HD.
    DupliFinder - $7 - shows which events the photos are in.
    iPhoto AppleScript to Remove Duplicates - Free
    Some users have reported that PhotoSweeper did the best in finding all of the dups in their library: i photo has duplicated many photos, how...: Apple Support Communities.
    If you have an iPhone and have it set to keep the normal photo when shooting HDR photos the two image files that are created will be duplicates in a manner of speaking (same image) but the only duplicate finder app that detected the iPhone HDR and normal photos as being duplicates was PhotoSweeper.  None of the other apps detected those two files as being duplicates as they look for file name as well as other attributes and the two files from the iPhone have different file names.
    iPLM, however, is the most versatile and best all around iPhoto utility to have.

  • HT2905 How does one get rid of duplicates with iTunes 11.0?

    Found an old Apple post about how to find duplicate files in iTunes. iTunes 11 seems to not have this ability, or at least the same way of doing things. Can someone explain how to find duplicates with 11?

    Right now you will have to do it manually by just sorting by track name and looking, or use a third-party tool such as Dupin. Apple has said that the Show Duplicates feature will return in a future update, but provided no timeframe.
    Regards.

  • Have iTunes version 10 .3 but do not understand cloud in iTunes 11.03 can someone explain it and also how do you find duplicates in new version and will the new version sync with my iPod Classic which I have had for 4 years

    I have iTunes version 10.03 which I love but my iPad Apple mini has iOS 7 but I don't understand the new iTunes what is the cloud shown next to the music and how can I find duplicates can anyone help me navigate the new iTunes and will the new version sync with my iPod Classic which is 4 years old

    The main differences between iTunes 11 and earlier versions are the loss of coverflow and ability to have multiple windows open.
    In Windows, you can restore much of the look & feel of iTunes 10.7 with these shortcuts:
    ALT to temporarily display the menu bar
    CTRL+B to show or hide the menu bar
    CTRL+S to show or hide the sidebar
    CTRL+/ to show or hide the status bar (won't hide for me on Win XP)
    Click the magnifying glass top right and untick Search Entire Library to restore the old search behaviour
    Use View > Hide <Media Kind> in the cloud or Edit > Preferences > Store and untick Show iTunes in the cloud purchases to hide the cloud items. The second method eliminates the cloud status column (and may let iTunes start up more quickly)
    If you don't like having different coloured background & text in the Album (Grid) view use Edit > Preferences > General and untick Use custom colours for open albums, movies, etc.
    With iTunes 11.0.3 and later you can enable artwork in the Songs view from View > Show View Options (CTRL+J) making it more like the old Album List view
    View > Show View Options (CTRL+J) also contains options to change the sorting of grid based views
    The cloud icons give you access to stream or download any qualifying past purchases that you don't currently have downloaded to the library.
    Regarding duplicates, things haven't really changed. Apple's official advice is here... HT2905 - How to find and remove duplicate items in your iTunes library. It is a manual process and the article fails to explain some of the potential pitfalls.
    Use Shift > View > Show Exact Duplicate Items to display duplicates as this is normally a more useful selection. You need to manually select all but one of each group to remove. Sorting the list by Date Added may make it easier to select the appropriate tracks, however this works best when performed immediately after the dupes have been created.  If you have multiple entries in iTunes connected to the same file on the hard drive then don't send to the recycle bin. Use my DeDuper script if you're not sure, don't want to do it by hand, or want to preserve ratings, play counts and playlist membership. See this thread for background and please take note of the warning to backup your library before deduping.
    (If you don't see the menu bar press ALT to show it temporarily or CTRL+B to keep it displayed)
    Yes, iTunes 11 will support your iPod classic.

  • Help with Finding Duplicate records Query

    HI,
    I am trying to write a query that will find duplicate records/cases.
    This query will be used in a report.
    So, here are the requirements:
    I need to find duplicate cases/records based on the following fields:
    DOB, DOCKET, SENT_DATEI was able to do that with the following query. The query below is able to give me all duplicate records based on the Criteria above
    SELECT      DEF.BIRTH_DATE DOB,

    //I AM GOING TO CALL THIS QUERY 'X'Now, the information to be displayed on the report: defendants Name, DOB, District, Docket, Def Num, Sent Date, and PACTS Num if possible.
    The problem that I need help on is how to combine those queries together (what I mean is a sub query). the 'X' query returns multiple values. please have a look at the comments on the query below to see what I'm trying to achieve.

    If I got it right, you want to join table USSC_CASES.DEFENDANTS to duplicate rows in USSC_CASES. If so:
    SELECT  INITCAP(DEF.LAST_NAME) || ' ' || INITCAP(DEF.FIRST_NAME) || ' ' || INITCAP(DEF.MIDDLE_NAME) DEFENDANT_NAME,
            DEF.BIRTH_DATE DOB,
            TRIM(DIST.DISTRICT_NAME) DISTRICT_NAME,

            S.DEF_NUM DEF_NUM,
            S.SENT_VIO_DATE SENT_DATE,
            DEF.PACTS_ID PACTS_NUM
      FROM  USSC_CASES.DEFENDANTS DEF,
             SELECT  *
               FROM  (
                      SELECT  S.*,
                              COUNT(*) OVER(PARTITION BY DEF.BIRTH_DATE, S.DOCKET, S.SENT_VIO_DATE) CNT
                        FROM  USSC_CASES.SENTENCES S

       AND  S.CASE_TYPE_CODE = 10
       AND  S.USSC_ID IS NOT NULL
      ORDER BY DEFENDANT_NAME;If you want to exclude duplicates from the query and do not care which row out of duplicate rows to choose:
    SELECT  INITCAP(DEF.LAST_NAME) || ' ' || INITCAP(DEF.FIRST_NAME) || ' ' || INITCAP(DEF.MIDDLE_NAME) DEFENDANT_NAME,
            DEF.BIRTH_DATE DOB,

  • Finding duplicate values in a column with different values in a different c

    I'm finding duplicate values in a column of my table:
    select ba.CLAIM_NUMBER from bsi_auto_vw ba
    group by ba.CLAIM_NUMBER
    having count(*) > 1;
    How can I modify this query to find duplicate values in that column where I DON'T have duplicate values in a different specific column in that table (the column CLMT_NO in my case can't have duplicates.)?

    Well, you can use analytics assuming you don't mind full scanning the table.....
    select
       count(owner) over (partition by object_type),    
       count(object_type) over (partition by owner)
    from all_objects;You just need to intelligently (i didn't here) find your "window" (partition clause) to sort the data over, then make use of that (the analytics would be in a nested SQL and you'd then evaluate it in outside).
    Should be applicable if i understand what you're after.
    If you post some sample data we can mock up a SQL statement for you (if what i tried to convey wasn't understandable).

  • How can I find duplicate photos without going through all 5000  one at a time?

    How can I find duplicate photos withough going through all 5000 one by one?  I have numerous duplications and used to be able to click on Edit and Find Duplicates and could clean up all the duplicates easily.  Now that option is gone.  I still have lots to delete.

    I do backup everything using Carbonite.Please don't tell me it is bad, too :-)  Also, especially with photo files, I do have other backups of those I am concerned about. Probably not the best in the world, but a log better than many people who I know about.
    Again, I really have not seen any problems with MacKeeper.  I imagine that if people do not read and follow instructions, they could have problems. For example, it is possible to scan all your files and see them in order of size. If you start deleting things, without knowing what you're deleting, you could cause trouble. Even when the computer scans for so-called junk files, you can look at them and decide for yourself if they are truly junk. I've never seen any that were not.
    So, I will look at the complaints anyway to see them. I am open to change, although I hope I do not need to drop Mackeeper as it does things like keeping tracking of applications updates that I need. Please note that I definitely am not a MacKeeper employee or anything close. Just using it and happy with the the results.
    I did download the recommend file for finding photo dupes and ran it.  There were very few duplicates, in any case, As I said before, the MacKeeper dupe finder was very slow when I ran it over ALL my files. That was a year ago and it did find many non-text dupes.

  • Script to find duplicate index and how can we tell if an index is REALLY a duplicate?

    Does any one have script to find duplicate index? and how can we tell if an index is REALLY a duplicate?
    Rahul

    One more written by Itzik Ben-Gan
    The first query finds exact matches. The indexes must have 
    the same key columns in the same order, and the same included columns but in any order. 
    These indexes are sure targets for elimination. The only caution would be to check for index hints. 
    -- exact duplicates
    with indexcols as
    select object_id as id, index_id as indid, name,
    (select case keyno when 0 then NULL else colid end as [data()]
    from sys.sysindexkeys as k
    where k.id = i.object_id
    and k.indid = i.index_id
    order by keyno, colid
    for xml path('')) as cols,
    (select case keyno when 0 then colid else NULL end as [data()]
    from sys.sysindexkeys as k
    where k.id = i.object_id
    and k.indid = i.index_id
    order by colid
    for xml path('')) as inc
    from sys.indexes as i
    select
    object_schema_name(c1.id) + '.' + object_name(c1.id) as 'table',
    c1.name as 'index',
    c2.name as 'exactduplicate'
    from indexcols as c1
    join indexcols as c2
    on c1.id = c2.id
    and c1.indid < c2.indid
    and c1.cols = c2.cols
    and c1.inc = c2.inc;
    The second variation of this query finds partial, or duplicate, indexes 
    that share leading key columns, e.g. Ix1(col1, col2, col3) and Ix2(col1, col2) 
    would be considered duplicate indexes. This query only examines key columns and does not consider included columns. 
    These types of indexes are probable dead indexes walking. 
    -- Overlapping indxes
    with indexcols as
    select object_id as id, index_id as indid, name,
    (select case keyno when 0 then NULL else colid end as [data()]
    from sys.sysindexkeys as k
    where k.id = i.object_id
    and k.indid = i.index_id
    order by keyno, colid
    for xml path('')) as cols
    from sys.indexes as i
    select
    object_schema_name(c1.id) + '.' + object_name(c1.id) as 'table',
    c1.name as 'index',
    c2.name as 'partialduplicate'
    from indexcols as c1
    join indexcols as c2
    on c1.id = c2.id
    and c1.indid < c2.indid
    and (c1.cols like c2.cols + '%' 
    or c2.cols like c1.cols + '%') ;
    Be careful when dropping a partial duplicate index if the two indexes differ greatly in width. 
    For example, if Ix1 is a very wide index with 12 columns, and Ix2 is a narrow two-column index 
    that shares the first two columns, you may want to leave Ix2 as a faster, tighter, narrower index.

  • How do I find duplicate songs which the latest itunes libary update does not show?

    How do you find duplicate songs in itunes which the latest updated version of itunes does not show, where the older version did?

    =Downgrading from iTunes 11 to iTunes 10.7=
    Try activating the sidebar, menu bar, and status bar and see if this is close enough to the previous version to make you content.  It is easier than downgrading and eventually you will be forced to run a newer iTunes unless you have an endless supply of the model computer you currently own.
    You may be able to go back with Time Machine but this may involve restoring other items too (https://discussions.apple.com/message/20441404).  Alternatively:
    Back up your computer first, in case the unexpected happens.
    Quit iTunes.
    Get iTunes 10.7 from http://support.apple.com/kb/DL1576 or the direct download link at:  http://appldnld.apple.com/iTunes10/041-7195.20120912.d3uzQ/iTunes10.7.dmg
    Do a few preparatory steps by making sure all iTunes components are not running and cleaning old files.   See https://discussions.apple.com/message/20475394.  Do steps 3 and 4.  Steps 6-8 may be also useful but I don't know if they are essential.  Some of the other steps are not necessary, duplicate steps listed later in my post or are perhaps even unhelpful in the process.
    Replace the iTunes 11 application with iTunes 10.7.  Simply dragging the application to the trash may not work. Lion (OSX 10.7) and newer systems have iTunes integrated into the operating system and deleting is a bit more involved.  Two ways to do this are:
    1.  (Easier) Use the shareware Pacifist utility (http://www.charlessoft.com/) to install iTunes 10.7 including all associated system files. Details at http://forums.macrumors.com/showpost.php?p=16400819&postcount=6
    2. (More work) Check this reference on how to delete the iTunes application itself:
        Delete iTunes in Mac OS X 10.7 Lion - http://osxdaily.com/2011/09/13/delete-itunes-in-mac-os-x-10-7-lion/
        After deleting the application there may be other files that need downgrading too. See the note about error -42408 at the end of this post. You may want to tuck these away somewhere safe until you have completed the installation of iTunes 10.7.  I have not tested this but ideally if newer versions are not found then the installer will put in the old versions. This may include these files in /System/Library/PrivateFrameworks/ which apparently get updated by iTunes 11:
    AirTrafficHost.framework
    CoreFP.framework
    DeviceLink.framework
    iTunesAccess.framework
    MobileDevice.framework
    After doing one of the two procedures above you will have to rescue the most recent old iTunes library from your iTunes > Previous Libraries folder. Rename it "iTunes Library.itl"  and replace the existing one in the iTunes folder. A newer version of iTunes irreversibly updates your library file so you have to replace it with the old one or you will get an error message. Note, this will revert your library to the version at the time of the upgrade and you will have to update any changes made since.  See:
    https://discussions.apple.com/message/20401436 - turingtest2 11/2012 post on rebuilding empty/corrupt library from previous iTunes library file after upgrade/crash.
    iTunes: How to re-create your iTunes library and playlists - http://support.apple.com/kb/ht1451
    Other issues:
    - https://discussions.apple.com/message/20432309 - solution to mobile devices saying they need to be restored after downgrading
    - If you encounter error -42408:
    iTunes: Advanced iTunes Store troubleshooting - http://support.apple.com/kb/TS3297 > Specific Conditions and Alert Messages: (Mac OS X / Windows) - including specific error codes.
    Alternatively, check https://discussions.apple.com/message/20441424 which requires you have a Time Machine backup (though possibly if you remove the newer version of these files old ones may be installed with the iTunes 10.7 installer - untested).  A  variant of this is at: https://discussions.apple.com/message/20448184

  • How do I find duplicate words in a Numbers spreadsheet?

    Hello, I've created my first document on Numbers and am trying to figure out how to find duplicate words. Ideally, a list of words that repeat in the document and how many times. Is this possible? Thank you in advance for the advice

    It's easy enough to find and count duplicate entries, especially if they are all in a single column, but if you want to count individual words within multi word entries, the problem is more complicated.
    Here's an example for the 'simple' case, using a familiar 155 word passage from English literature.
    The words in the passage are separated into a single line for each word, and stripped of all punctuation. This may be done in Pages, or in Text edit, or in pretty much any word processing software or text editor. Paste the passage into a WP or text document, then use the application's Find/Replace feature to replace all of the spaces with returns. I would also do a second pass replacing all double returns with single returns, then repeat that until Find/Replace reported replacing zero occurrences.
    Punctuation was stripped using Find/Replace
    The prepared list was pasted into column A of a Numbers table.
    Formulas:
    B2: =COUNTIF($A$1:A2,A2)
    C2: =IF(AND(B>1,B=COUNTIF($A,A2)),ROW()-1,999999)
    Fill both down their respective columns to the end of the table.
    The small table is inserted as a Basic table using the Tables button. It contains a Header row, but no Header columns.
    Formula:
    A2: =IFERROR(OFFSET(Table 1 :: $A$1,SMALL(Table 1 :: $C,ROW()-1),COLUMN()-1),"")
    Fill right into B2, then fill both down to the end of the table.
    Descriptions of the functions used, along with their syntax and at least one example of their use in a table are available in the Numbers '09 User Guide, which may be downloaded via the Help menu in Numbers.

  • How do I find duplicate images in Aperture?

    How do I find duplicate images in Aperture AFTER importing my entire library from iPhoto? There must be a way to do that, right?
    Please let me know the secret.
    Thanks!

    Léonie,  Thank you for your rapid reply!
    I am using Aperture Version 3.4.3 and 9.4.2.  I downloaded the Duplicate Annihilator but it gives me an error message that says this:
    I have no idea what that is all about since I am using this library in iPhoto and Aperture. I already sent the company an email asking about the problem.
    I am seeing dupes that came from my original photos in iPhoto and from iPhoto PhotoStreams with monthly dates; these are listed in my Apertrure Projects listing. Is there a way to SAFELY dump these dupes?
    Thanks!

  • Finding duplicate entries in address book

    I am using Address Book 5.0.3, where I have been using LinkedIn's CardMunch to import contact details via my iPhone. However, I now end up with three distinct issues regarding duplicate entries:
    1/ two people with the same name, e.g. John Smith, but I know they are two separate people and they work for different companies.
    2/ After an import, I may have some duplicate entries, say Alan Walker, who has moved from company A to company B and I want to replace his old contact details with the new information.
    3/ two duplicate entries the same name, say Brian Vickers, both of which refer to the same person who still works for the same company, but has new contact details or additional data, such as a mobile number that I did not have before.
    4/ two duplicate entries that are identical. E.g. I imported the same card twice for some reason.
    5/ multiple entries marked 'Cannot Read Name', where CardMunch had a problem, but I know they are different people and I have to edit these to manually enter the correct information.
    Unfortunately the Address Book find duplicates function, whilst it works, does nothing useful. The only option I am presented with is 'Merge', which in all of the scenarios above apart from item 4 I do not want to do a merge function - I want to either 'Mark as NOT Duplicates' (item 1/), 'Replace Selected Fields' e.g. show me the two cards side by side and allow me to select which fields from which card are to be kept, replaced or removed and then implement the merge (item 2), "Add New Information' but allow me to select the label for that information before merging so that if someone has a new iPhone, but is still keeping their old mobile, I can select the field label correctly and then merge (item 3) or 'Edit Card' which allows me to open any identified duplicate and add in missing information that would mean that it is no longer a duplicate item.
    Can anyone suggest a way of doing this, or can Apple's developers please add these features to the Address Book App as soon as possible?
    Thanks, Russ Taylor

    books06,
    Welcome to Apple Discussions.
    It depends upon which version of Address Book you are using, and your definition of "view."
    1. Address Book 3.1.1 Help
    2. Address Book 4.0.3 Help: Combining duplicate cards and information
    To find and merge duplicate cards:
    1. Choose Card > "Look for Duplicate Entries."
    2. Address Book tells you if it finds duplicate cards, cards containing duplicated information, or both.
    3. Click Merge to merge duplicate cards and remove redundant information on cards.
    When Address Book merges duplicate cards, it creates a single card for the contact containing all of the unique information from each merged card. Address Book uses the picture from the merged card appearing first in the list.
    To merge selected cards only, Command-click to select the cards you want to combine and choose Card > Merge Selected Cards. Address Book creates a single card using the name and picture of the selected card appearing first in the list.;~)
