SQL FIND DUPLICATES IN TABLE

May 28, 2008

I have this script bellow which does what it is supposed to. However it only outputs the cust_id. I want it to show all the columns in the table. How would I do this?



SELECT cust_id
FROM cust_table
WHERE cust_name in ('Billy','John') and rownum < 100
GROUP BY cust_id
HAVING COUNT(*) > 1;

How Do I Find Duplicates In A Table.

Apr 15, 2008

Hi,
 I have table which stores the fund name and its data. We get quarterly information from the fund co. Suppose if the user wants to add a fund thats not in our database we let then add a ClientFundId and a FundName. But may be after sometime the fund company may add that fund in the next quarter.. So how do i get rid of Duplicated Data..
In the ClientFundId column we can a 9 letter Aplhanumeric or a 5 letter character but if the fund co.. provides those values the 5 letter characters are stored in Ticker column and the 9 letter words are stored in Cusip column.. So i just wrote this query hoping i could retrieve the duplicate values but it didnt list any..but i found one this is my query..
 Select
FundId,
Cusip,
Ticker,
ClientFundId,
FundName,
ShortName
From Fund
Where

ClientFundId = Ticker
or
ClientFundId = Cusip
 Any help will appreciated
Thanks
Karen

How Do I Find The Duplicates In A Table

Dec 11, 1999

does someone have a querry to display the duplicate records in a table.

Table:
zipcode dma

My data upload is failing because there is a primary key on zipcode and the source data (42k records) has about 50 duplicate zipcode records in it. It is possible that there is a unique combo of zipcode / dma but I need to identify the duplicate records to determine that.

SQL Server 2008 :: How To Find Duplicates In A Table As Per Particular Column

Nov 2, 2015

I am having a main table and temptable.

Every sunday, new data will be loaded from temptable to main table. I have to make sure that, duplicates does not get loaded from temptable to maintable.

For example, if last sunday a record gets loaded from temp to main. If this sunday also the same record is present then it means that is a duplicate.

The duplicate is decided on below scenario

select 'CodeChanges: ', count(*) from CodeChanges a, CodeChanges_Temp b
where a.AccountNumber = b.AccountNumber and
a.HexaNumber = b.HexaNumber and
a.HexaEffDate = b.HexaEffDate and
a.HexaId = b.HexaId and

[Code] ...

Yesterday (Sunday) , data from temp got loaded onto maintable but with duplicates.

There is a log which just displays number of duplicates.

Yesterday the log displayed 8 duplicates found. I need to find out the 8 duplicates which got loaded yesterday and delete it off from main table.

There is a column in both tables which is 'creation date and time'. Every Sunday when the load happens this column will have that day's date .

Now i need to find out what are all the duplicates which got loaded on this sunday.

The total rows in temp table is : 363
No of duplicates present is : 8

I used below query to find out the duplicates but it is returning all the 363 rows from the maintable instead of the 8 duplicates.

Select 'CodeChanges: ', * from CodeChanges a where
exists
( Select 1 from CodeChanges_Temp b where
a.HexaNumber = b.HexaNumber and
a.HexaEffDate = b.HexaEffDate and

[Code] ...

Need finding the duplicate records which has creation date time as '2015-11-01 00:00:00.000' and all the above columns mentioned in the query matches.

Example

Few colums only metioned below

creationdateandtime HexaNumber HexaCode
1. 1987-10-01 00:00:00.000 5 3
2. 2015-11-01 00:00:00.000 5 3

So here the second record is duplicate. This is what I am trying to find.

Query To Find Duplicates

Jul 19, 2004

Hi

I am trying to find when a name has been entered more than once into 1 database table.

I'm currently doing something like this (can't remember exactly, not at work)


SELECT COUNT(*) AS Cnt, Name
FROM tblTable
GROUP BY Name
ORDER BY Cnt Desc

This brings back all the Names in the database and tells me which are duplicates but I want to just have the results of the duplicate values and not the single values.

Hope you can help.

Thanks

Transact SQL :: How To Find Duplicates For Different Fields

Oct 27, 2015

I have a table that has Serial numbers and MSDSID numbers and many other fields in the table.

What I need to figure out is if the table contains a distinct Serial number with different MSDSIDs.

So If I have in the table

Serial          MSDSID          Date          Size...
001                 20            1/1/2015        5
002                 21            1/1/2015        3
001                 22            2/1/2015        1
003                 21            3/1/2015        1
004                 23            1/15/2015      5
003                 22            1/20/2015      6
004                 23            2/21/2015      5
002                 21            4/25/2015      4

I would like the results to show:

Serial            Count
001                  2           the count is 2 because Serial 001 has an MSDSID of 20 and 22
002                  1           the count is 1 because Serial 002 only has MSDSID 21
003                  2           the count is 2 because Serial 003 has an MSDSID of 21 and 22
004                  1           the count is 1 because Serial 002 only has MSDSID 23

It would be even better if the results just showed where the count is greater than 1.

Identifying Duplicates - Find Where 2 Or More Records Have Same Rank

Sep 26, 2014

I have this query below that I created to do a count, but I don't think this is what I needed.

I need to find the duplicates. Example, if

CLI_ID1 12345 has 4 CLIP records, each CLIP record should have a different CLIP rank. I need to find scenarios where 2 (or more) of the CLIP records have the same CLIP RANK. If there are duplicate CLIP_RANKs within the same CLI_ID,

Select Distinct
cli_id1, count(clip_rank) countrank
FROM impact.dbo.CLI
LEFT JOIN impact.dbo.CLIO ON CLI.CLI_ID1 = CLIO.clio_id1

left join
impact.dbo.clip ON cli_id1 = clip_id1
Where (clio_trm = '' or clio_trm = NULL or clio_trm is null)
group by cli_id1
order by cli_id1

Need To Find Instances Of Duplicates Within A Column; Joining 2 Tables.

Aug 22, 2007

My basic situation is this - I ONLY want duplicates, so the oppositeof DISTINCT:I have two tables. Ordinarily, Table1ColumnA corresponds in a one toone ratio with Table2ColumnB through a shared variable. So if I queryTableB using the shared variable, there really should only be onrecord returned. In essence, if I run this and return TWO rows, it isvery bad:select * from TableB where SharedVariable = 1234I know how to join the tables on a single record to see if this is thecase with one record, but I need to find out how many, among possiblymillions of records this affects.Every record in Table1ColumnA (and also the shared variable) will beunique. There is another column in Table1 (I'll call itTable1ColumnC) that will be duplicated if the record in Table2 is aduplicate, so I am trying to use that to filter my results in Table1.I am looking to see how many from Table1 map to DUPLICATE instances inTable2.I need to be able to say, in effect, "how many unique records inTable1ColumnA that have a duplicate in Table1ColumnC also have aduplicate in Table2ColumnB?"Thanks if anyone can help!-- aknoch

T-SQL (SS2K8) :: Find Matching Phone Of Person Based On Relation Type - Duplicates

Aug 11, 2014

I have a patient record and emergency contact information. I need to find duplicate phone numbers in emergency contact table based on relationship type (RelationType0 between emergency contact and patient. For example, if patient was a child and has mother listed twice with same number, I need to filter these records. The case would be true if there was a father listed, in any cases there should be one father or one mother listed for patient regardless. The link between patient and emergency contact is person_gu. If two siblings linked to same person_gu, there should be still one emergency contact listed.

Below is the schema structure:

Person_Info: PersonID, Person Info contains everyone (patient, vistor, Emergecy contact) First and last names
Patient_Info: PatientID, table contains patient ID and other information
Patient_PersonRelation: Person_ID, patientID, RelationType
Address: Contains address of all person and patient (key PersonID)
Phone: Contains phone # of everyone (key is personID)

The goal to find matching phone for same person based on relationship type (If siblings, then only list one record for parent because the matching phones are not duplicates).

T-SQL (SS2K8) :: Rank Duplicates But Only Rows Involved In Duplicates?

Oct 22, 2014

I have a table with 22 million Business records. I can see that there are duplicates when I group by BusinessName and Address and Phone. I'd like to place only the duplicates into a table, with a ranking, oldest business key gets a ranking of 1.

As a bonus I'd like each group to have a distinct group name (although not necessary, just want to know how to do this)

Later after I run more verifications to make sure these are not referenced elsewhere I'll delete everything with a matchRank > 1 out of the main Business table.

DROP TABLE [dbo].[TestBusiness];
GO
CREATE TABLE [dbo].[TestBusiness](
[Business_pk] INT IDENTITY(1,1) NOT NULL,
[BusinessName] VARCHAR (200) NOT NULL,
[Address] VARCHAR(MAX) NOT NULL,

Removing Duplicates In The Table

Mar 21, 2014

The database has Name,Email, and skill. Though the name is distinct it is repeated as it has different skills. I would like to remove duplicate names and add the corresponding skill to the only one row.

From the stored procedure, combining 3 tables I got the output as:

NameemaildepartmentSkill
ArunemailidTech teamTechnical
ArunemailidTech teamLeadership
ArunemailidTech teamDecision Making
BinayemailidMarketingTechnical
BinayemailidMarketingDecision Making

I would like to remove the duplicate Name fields and combine the Skill in a single row as other fields are same.

So the output should be

NameemaildepartmentSkill
ArunemailidTech teamTechnical, Leadership, Decision Making
BinayemailidMarketingTechnical,Decision Making

Duplicates In Table Field

Aug 7, 2014

Im trying to look for duplicates in a table field.. field name is alphanumericCol and table is a user defined table...This is my trigger:

ALTER TRIGGER [dbo].[DUPLICATES]
ON [dbo].[AMGR_User_Fields_Tbl]

FOR INSERT, UPDATE
AS
DECLARE @Alphanumericcol VARCHAR (750)

-- This trigger has been created to check that duplicate rows are not inserted into table.

-- Check if row exists
SELECT @Alphanumericcol
FROM Inserted i, AMGR_User_Fields_Tbl t
WHERE t.AlphaNumericCol = i.AlphaNumericCol
AND t.Client_Id = i.Client_Id
-- (@Alphanumericcol = 1)
-- Display Error and then Rollback transaction
BEGIN
RAISERROR ('This row already exists in the table', 16, 1)
ROLLBACK TRANSACTION
END

The result i get is, if i input a duplicate number it fills in a null in the field so my question is how do i get it to tell me its duplicate and let me insert a new one

Process For Removing Duplicates In Table?

May 18, 2012

I have a very large table that can contain up 3 to 5 duplicate records. Every month around 100,000 new records come in. Sometimes it's an ammended record, other times is just duplicated by error.

Is it possible to keep the latest record dumped into the table and delete the others? Does SQL track the order of the data being dropped into the table?

The layout would look like this. There are 10-15 other columns in the table where adjustments can also be made.

Lease# Year Month Production
12345 2008 10 1,231
12345 2008 10 1,250

Table Joins Causing Duplicates?

May 15, 2015

I have a table with call data (ContactID, Queues Entered, Call Status, Date & Time Stamps etc). Each entry relating to a contact ID goes onto a new row. The first row for a contact is the date and time it is created. It then captures the queue (or queues) it enters before it is answered. Finally, it captures when the call is released (Completed).

I'm trying to link all this data into one single row per contact ID to make it easier to report on.

I started off by using DISTINCT to pull back all of the Contact ID's. I then used a Left Join to pull back the date and time of creation. I created a further Left Join to pull back the first queue that it entered and so on.

When I did this, I started getting duplicates. This is because some calls enter more than one queue.

How can I do this so that it only has one ContactID per row. Also, for the Queue, is there anything I can do to ensure it pulls back the first Queue it enters? (These are time stamped). Subsequently, I would then need to add the second and third queue it enters in other columns. (A call can enter a maximum of 3 queues).

MSSQL Dbo Table Duplicates On Host Server

Apr 26, 2005

(i am not sure which forum to post this too)
Hi, I imported a table onto my host's server, table_Login which has username password, and userID. userID is Primary Key & identity.
When I had my code do insert of new user, I was getting error the Login.userID doesn't allow null values. Which shouldn't have mattered because userID is an identity.
After making a diagram from Enterprise Manager, I noticed that I have two Login tables (although only one shows in Enterprise Manager's "Table" node view. The second table, which had none of the constraints that my table of the same name which is listed under the "Table" node does; appears to be the table which is being written to by my code.
I can't find this table, Login(dbo), through Enterprise Manager, nor am i sure how to access it through Query Analyzer. Needless to say, I don't like this arrangement. and well tech support for this host seems to leave a lot to be desired.
Anyone know what needs to be done so that I can fix it or fight with tech support to convince them that they should?

But firstthey want to find how many unique or duplicate entries they have acrossall the 10 databasesAssumptions:1. All the databases reside on the same server. (This is just anassumption, not the real environment at customer site)2. Databases can not be merged before it is found how many unique orduplicate rows exist.Table under consideration:Message(HashID PK,....)# of rows in Message table in each of databases: 1 MillionHere is my question: How can I find how many unique or duplicateentries they have across all the 10 databases. I easily find uniquerows for two databases with a query like this:SELECT COUNT(A.HasID) FROM db1.dbo.Message A LEFT OUTER JOIN ONdb2.dbo.Message B ON A.HashID = B.HashID WHERE B.HashID IS NULLHow can I do this for 10 databases. This will require factorial of 10queries to solve this problem.I will appreciate if someone can provide hint on this.RegardsAK

T-SQL (SS2K8) :: Delete Duplicates From Table Based On Two Columns?

May 20, 2015

Assuming I have a table similar to the following:

Auto_ID Account_ID Account_Name Account_Contact Priority
1 3453463 Tire Co Doug 1
2 4363763 Computers Inc Sam 1
3 7857433 Safety First Heather 1
4 2326743 Car Dept Clark 1
5 2342567 Sales Force Amy 1
6 4363763 Computers Inc Jamie 2
7 2326743 Car Dept Jenn 2

I'm trying to delete all duplicate Account_IDs, but only for the highest priority (in this case it would be the lowest number).

I know the following would delete duplicate Account_IDs:

DELETE FROM staging_account
WHERE auto_id NOT IN
(SELECT MAX(auto_id)
FROM staging_account
GROUP BY account_id)

The problem is this doesn't take into account the priority; in the above example I would want to keep auto_ids 2 and 4 because they have a higher priority (1) than auto_ids 6 and 7 (priority 2).

How can I take priority into account and still remove duplicates in this scenario?
