How to remove duplicate pictures

I imported all my photos in the photo library. How to remove duplicates of Photos (version 1.3) on OS X El Capitan without 3rd party software?

Photos don't have a tool to detect the duplicates library. It relies on detecting when you import photos.

If you intentionally import duplicates, you can only search for them manually, for example by sorting the photos of the capture date, if duplicates will appear side-by-side in moments.

To search for duplicates, you need third-party software. These three are safe to use with Photos:
- Powerphotos: fat cat Software
- Duplicate Annihilator: propaganda Brattoo Software - products
- PhotoSweeper: http://overmacs.com/photosweeper.html

JS: How to remove duplicates in a table?

I guess there's a simple solution...

Hey!

Maybe something like this:

Array.prototype.unique = function (){
    var r = new Array();
    o:for(var i = 0, n = this.length; i < n; i++){
        for(var x = 0, y = r.length; x < y; x++){
            if(r[x]==this[i]) continue o;}
        r[r.length] = this[i];}
    return r;
}

Use:

var myArray = ["a","b","c","c","a","d","b","b"];
alert(myArray.unique());

Hope that helps.

Photo library - iCloud how to remove duplicates

All, someone knows something about OSX/IOS 'Photos' app will detect and remove duplicates photo9? My library 'Photos' 63 299 photos & videos of 2135 from may 2016 and at least 10,000 + of these photos are duplicates (based on an analysis of Photosweeper). I have checked the results of the analysis of Photosweeper by doing a manual visual comparison and check images original in iphoto library (using the function location of show) and confirmed that these 10 000 + photos are images duplicate identical with names of different files in different parts of the photo library database.

So what is happening and how to stop 10-15% of my picture library being duplicate files! I will raise this directly with the apple support payment for the 1 TB icloud service to cover my very large library 'Photos', which should probably be just a large Photo library!

A few other comments for those who have a double problem:

-L' old iPhoto application used to "detect duplicates" when import but the new application 'Photos' does not. Anyone know about this?

-J' saw the documentation from apple saying the icloud search duplicates in 'Photos' when in the icloud, but clearly not work or it does not work if duplicates exist also in the version of the imac to the library 'Photos '.

-Beware of apps that claim to find 'photos' duplicate and are recommended on various Internet sites, a number of them don't work with the old iphotos app the new application 'Photos' (I discovered after you pay and download). If you need a remover of duplicates of photos that work with 'Photos' review and stay away from any application that do not specify clearly and explicitly he works with "photos" and has been seen since the release of the Photos app.

+ I paid $10 for "Gemini" dual Finder and has been a complete waste of time that didn't work only not with the "Photos" application (it wasn't not clear documentation or support, and when I trigger it supported by Macpaw that they said gemini does not support photos and told me to buy another app macpaw - I told them to go jump in a Lake).

+ I found very good Photosweeper that you can set to match exact or variable (for example photos of accidental burst which are 99.99% identical but 0,1s collapse) and then you can right click to view original file / image in the library to manually check duplicate (if you are paranoid like me) - there are many other paid apps that also make this store then around

Photos detects duplicates when you import pictures and when you synchronize with ICPL

Photos does not analyse the duplicates, but checks for them during import and download of IPCL

There are a few duplicate programs that are tested as safe with Photos, including PowerPhotos, PhotoSweeper for the pictures and Duplicate Annihilator for Photos - do not use a tested and documented as safe\

And I'm not clear what your post is about since you are asking how to find duplicates and then provide a good answer - photoSweeper - it is one of the safe and effective ways to remove duplicates for Photos

3.6.2 the numbers help find and remove duplicates in 2 columns

Could someone help me please. I run a karaoke business. As you may have guessed I have books with many songs, 64 000 and more than 75% of these songs are duplicates so you can imagine by train to sort. Option 1 I could manually go through my list by removing duplicates or option 2 attempt to find a formula that works save me hours of blind deletion. Is there someone out there who can help? It would be much appreciated thanks.

Here is a sample of the document I'm working.

Hi robi.

Here is a solution of Craig s. Ruddock in this discussion Re: duplicates warning formula

Formula in B2 (fill down)

= IF (COUNTIF($A,A) = 1",","duplicate")

Now sort by column A

Remove all but one of the "duplicate" lines for each song.

Kind regards

Ian.

How to remove duplicate rows (not exactly duplicate)
Hi I have lines like this in a table emp

ENO ename age
1 25
26 2
3 25
4 26

I don't have repititve enames... (here in this example: A).

If I find something like that I should keep the first line and delete all other lines.

How can I do this?

as unique empowerment of ename... (except for this)
Hi Renon,
There are different ways could remove duplicate rows, but Franks solution seems good.
With the help of ID you can get good results in the largest data sets. If you want Nwe minutes remain in the database and all others to delete then make use of eno and not rowid.
```
DELETE FROM emp y
WHERE       eno != (SELECT   Min(eno)
                    FROM     emp x
                    WHERE    x.NAME = y.NAME
                    GROUP BY NAME)

How to remove duplicates from comma separated string

Hi all
I have an obligation to remove duplicates of string separated by commas:
Some examples of code (real data can be in millions)
{code}
create table test_dup_del (num number (10), dup_val varchar2 (100));
insert into test_dup_del values (1234, '1, 2, 3, 4, 3, 1');
insert into test_dup_del values (4567,'1, 2, 2, 4, 4, 1');
insert into test_dup_del values (7894,'1, 2, 1, 3, 3, 1');
insert into test_dup_del values (1478, '1, 2, 4, 4, 3, 2');
insert into test_dup_del values (2589, '1, 2, 1, 2, 1, 2');
commit;
(code}
my output would be:
1234, 1, 2, 3, 4'
4567, '1, 2, 4'
7894, '1, 2, 3'
1478, 1, 2, 3, 4'
2589, 1, 2'
Thank you

How to remove duplicates in my Lightroom Catalog?

I have merged an old Lightroom Catalog in my Lightroom hand catalogue and accidentally created duplicate images, thousands of them (sometimnes, geometry), I suppose I must have completed the process before, foregotten and not deleted catalogs I merged after that I've merged them... then go back and redo the process... thus creating duplicates.
My problem is I want to remove duplicates without losing the edited versions. only those that I have meged in. The file has a lot of images which is not duplicated, so I can't start the process again?

You can remove duplicates of Lightroom is removing recognizes them in the grid view.

However, there are a few Plugins available. Here's a Journal http://www.lightroomfanatic.com/tutorials/advanced/finding-duplicate-images-lightroom-cata /

How to remove duplicates
Alcon,

Can you please give me good suggestion how to show any record of duplicate records.

number of im get many duplicates, but I want to show a place with many, if im using ROWNUM = 1 displays a record altogether. can you give me an idea it is possble to show one.

We have three location only as ABC, BCD, JKL but we N no lot numbers...

for example. im getting output is

Does lot no location
ABC 123
123 BCD
ABC 145
JKL 145
JKL 178
ABC 178
190 BCD
ABC 190

now, I want to indicate the output below
Does lot no location
ABC 123
ABC 145
JKL 178
190 BCD
Try this
```
SELECT LX.LOT,MIN(L.LOCPREFIX) AS LOC
FROM      LOTXLOCXID LX,
     LOC L,
     SKU S
WHERE L.LOC=LX.LOC
AND S.SKU=LX.SKU
AND S.PVTYPE='GFM'
GROUP BY LX.LOT
```
The column that is used in the TEXT-TO-SPEECH function should not be used in GROUP BY for your query.

And when you are a collection, you do not need to use SEPARATE

How to remove duplicates from the PL - SQL table?

Hi gurus,

I have a PL - SQL table with the following structure
Authors (SR_NO, Auth_Code, Change_Date, cost)

This table is filled using a slider. However, this table can have a few lines in double (for column (Auth_Code)
for example

SR_NO      Auth_Code       Change_Date                       Cost
1               A1             14-FEB-09 08.18.47 AM          11.00
2               A2             14-FEB-09 08.18.56 AM       2839.00
3               A1             15-FEB-09 08.00.02 AM      1299.00
4               A1             15-FEB-09 07.00.00 AM        789.00
5               A3             14-FEB-09 08.18.56 AM        312.00
6               A4             14-FEB-09 08.19.02 AM        233.00

I need to get the above result set select the separate lines of Auth_Code including the Change_Date is maximum (and store in another PL - SQL table for treatment later or even the removal of this table will be also!)

of the data A1 is duplicated and a maximum Change_Date above = 15 February 09 08.00.02 AM.
Where my PL - SQL Table that results must have given below

SR_NO      Auth_Code       Change_Date                       Cost
2               A2             14-FEB-09 08.18.56 AM       2839.00
3               A1             15-FEB-09 08.00.02 AM      1299.00
5               A3             14-FEB-09 08.18.56 AM        312.00
6               A4             14-FEB-09 08.19.02 AM        233.00

I'm not very aware of the PL - SQL tables and there is no chance to change the existing cursor that fills the data in this table PL - SQL.
I guess that I need to compare each record of PL - SQL table with others, but do not know how to do this.

Could you please help?

How to remove duplicates of many of my images - it seems that everything I do only compooiunds the question and now I have multiples of duplicates

Suggest that you first spread malware as the cause of the problem by following these steps:

I. - delete your temporary files

Click Start > all programs > Accessories > System Tools > Disk Cleanup

II. - have your system scanned as a result of security/antivirus installed.

III. - download, install, update, and run analyses both of these tools free anti-malware:

How to avoid duplicates on a column with condition

Hi all
I need some advice here. At work, we have an Oracle APEX application that allow the user to add new records with the decision of the increment automatic number based on the year and the group name.
Said that if they add the first record, group name AA, for 2012, they get the decision number AA 1 2013 as their record casein displayed page of the report.
The second record of AA in 2013 will be AA 2 2013.
If we add about 20 records, it will be AA 20 2013.
The first record for 2014 will be AA 1 2014.
However, recently, we get a claim of the user on two files of the same name of group have the same number of the decision.
When I looked in the history table and find that the time gap between 2 record is about 0.1 seconds.
In addition, we have the correspondence table which allows the user admin update the sequence number start with the restraint that it must be greater than the maximum number of the current name of the current year.
This boot sequence number and the name of the group is stored together in a table.
And in some other case, the user can add a decision duplicate for related record number. (this is a new feature)
The current logic of the procedure to add the new record on the application are
_Get max record table with selected group name (decision_number) and the current year.
_INSERT in the folder table the new record came with the decision to number + 1
_ update sequence number of the number of the decision just added.
So instead of utitlising the process of editing the built-in automatic table of the APEX, I write a procedure that combine all three processes.
I have run some loop for continually perform this procedure, and it seems that it can generate autotically new decision unique number with time about 0.1 second difference.
However, when I increase the number of entry to 200 and let two users run 100 each.
If the time gap is about 0.01 second, double decision numbers are displayed.
What can I do to prevent duplicate?
I can't just apply a unique constraint here for three columns with condition because it can be duplicated in some special conditions. I don't know much about the use of lock and its impact.
This is the content of my procedure

create or replace

PROCEDURE add_new_case)

-ID just use the trigger

p_case_title IN varchar2,

p_year IN varchar2,

p_group_name IN VARCHAR2,

-decisionnumber here

p_case_file_number IN VARCHAR2,

-active

p_user in VARCHAR2

)

AS

NUMBER default_value;

caseCount NUMBER;

seqNumber NUMBER;

previousDecisionNumber NUMBER;

BEGIN

-execution immediate q '[alter session set nls_date_format = "dd/mm/yyyy"]';

SELECT count (*)

IN caseCount

OF CASE_RECORD

WHERE GROUP_ABBR = p_group_name

AND to_number (to_char (create_date, "yyyy")) = to_number (to_char (date_utils.get_current_date, "yyyy"));

SELECT max (decision_number)

IN previousDecisionNumber

OF CASE_RECORD

WHERE GROUP_ABBR = p_group_name

AND to_number (to_char (create_date, "yyyy")) = to_number (to_char (date_utils.get_current_date, "yyyy"));

IF p_group_name IS NULL

THEN seqNumber: = 0;

ON THE OTHER

SELECT Seq_number INTO seqNumber FROM GROUP_LOOKUP WHERE ABBREVIATION = p_group_name;

END IF;

IF caseCount > 0 THEN

default_value: largest = (seqNumber, previousdecisionnumber) + 1;

ON THE OTHER

default_value: = 1;

END IF;

INSERT INTO CASE_RECORD (case_title, decision_year, GROUP_ABBR, decision_number, case_file_number, active_yn, created_by, create_date)

VALUES (p_case_title, p_year, p_group_name, default_value, p_case_file_number, 'Y', p_user, sysdate);

-Need to update the sequence here also

UPDATE GROUP_LOOKUP

SET SEQ_NUMBER = default_value

WHERE the ABBREVIATION = p_group_name;

COMMIT;

EXCEPTION

WHILE OTHERS THEN

Logger.Error (p_message_text = > SQLERRM)

, p_message_code = > SQLCODE

, p_stack_trace = > dbms_utility.format_error_backtrace

);

LIFT;

END;

Many thanks in advance,
Ann

It's easier to solve for the case, while p_group_name is not null. In this case, you update a GROUP_LOOKUP line, so that you can select to update this line at the beginning, to prevent cases of two for the same group added at the same time. To do this, change the selection of GROUP_LOOKUP to:

SELECT Seq_number INTO seqNumber FROM GROUP_LOOKUP WHERE ABBREVIATION = p_group_name for an updated VERSION OF the SEQ_NUMBER;

and move this to be the first thing that did the procedure - before it has CASE_RECORD lines.

In the case when p_group_name is set to null, you have some object to be locked. I think the best you can do is to lock the entire table GROUP_LOOKUP:

the table lock in exclusive mode GROUP_LOOKUP wait 100;

The '100 expectation' means that he will wait until 100 seconds before giving up and trigger an error. in practice, that is expected to only wait a moment.

Exclusive mode allows others to read, but not to update the table.

UPDATES and the LOCK of the TABLE will be updates of other sessions wait for this transaction to validate. Queries from other sessions are not affected.

The locks are released when you commit or roll back.

How to remove duplicate Oracle lines and retain the last rows in double
Hello

I have millions of records in the table. Some values / duplicate rows are inserted into it.
I want to just delete the duplicate lines but I also want to keep the last duplicate line.
For example if a record is found three times, I want to delete the first and second record and keep
the third is to say the last inserted a.
