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 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

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

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 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?

It is a problem of display/reports rather than a problem of duplication of query data. The answer depends on what tools you use to query and display the data. You can use the clause "break it" I suggested earlier if you use SQL Plus.

Otherwise, you can try this based on the version of Oracle you are using. Someone else may be able to get the data in a single pass.
```
SELECT decode(emp_id, 1, department_name) department_name, employee_name, salary
FROM(SELECT department_name, employee_name, salary,
       ROW_NUMBER() OVER (PARTITION BY department_name order by department_name, employee_name) AS emp_id
     FROM department
     LEFT OUTER JOIN employee ON (department.department_id = employee.department_id)
ORDER BY department_name, employee_name, emp_id);
```

How to remove duplicates in two separate lines in SQL?

Hello

I need to identify the data in double with two separate lines. See my below data structure.
INDEX OF NAMES NAME_1 START_DATE END_DATE FLAG VALUE
B ON 275 SE 13/12/2005-31/12/2010 1
SELF 1 375
SELF 1 475
ON 275 SE 2 B 13/12/2005-31/12/2010
SELF 2 375
SELF 2 475
ON SE 175 13/12/2006 AND 31/12/2010 B 3
SELF 3 375
SE ON 3 475

This is my sample data. Here, the data is mirrored with different index columns. INDEX 1 and 2 contains the same combination group. I so need to identify one of the combination double (i.e. INDEX 1 or 2). Anyone can come up with the exact solution?

Thank you

I thought it had to do with the order of the INDEX field. The query checks only the value of the previous INDEX value.

I think I found what the problem was.

Try this:

with test_table as
(select 'SUR' NAME, 'SE' NAME_1, '275' VALUE, to_date('13/12/2005','DD/MM/YYYY') START_DATE, to_date('31/12/2010','DD/MM/YYYY') END_DATE, 'B' FLAG, 1 IND from dual union all
select 'SUR', 'SE', '375', null, null, 'A', 1 from dual union all
select 'SUR', 'SE', '475', null, null, 'A', 1 from dual union all
select 'SUR', 'SE', '275', to_date('13/12/2005','DD/MM/YYYY') ,to_date('31/12/2010','DD/MM/YYYY') ,'B', 2 from dual union all
