How would you differentiate duplicates in a table without deleting.
I have a table name ANGEL that contains duplicate value and i want to append a letter V to the duplicates instead of deleting them.
INSERT
INTO [Table2Distinct]Â Â Â Â Â Â Â Â
([CLAIM_NUMBER]Â Â Â Â Â Â Â Â
,[ACCIDENT_DATE]
[code]....
I used the above query and it still inserts all the duplicate records. What is wrong with my statement?
I have table with columns as ID, DupeID1, DupeID2. ID column is unique. DupeID1 and DupeID2 -- the combination should only be there once. I don't want reverse combination of duplicates, i.e. DupeID2, DupeID1 in the table. How can I delete the reverse duplicates from this table?

Hey all.
I have a table with 100,000 plus records in it, and some are duplicates. Is there any way to delete one of them and not the other. For instance, if I duplicate the table I could run this query.
<cfquery name="query1" datasource="datasource">
DELETE DISTINCT
FROM tablename
WHERE FirstName in ( SELECT FirstName from tablename1 where tablename1.FirstName = tablename.FIRST_NAME AND tablename1.LastName = tablename.LAST_NAME AND tablename1.State = tablename.STATE)
</cfquery>
However, it doesn't work. I know the distinct is not correct. But does anyone know how to achieve this, I have looked all over, and everything I try deletes both records. I was thinking of using some kindof count statement, but it still deletes both of them. Please help. Thanks
Hello,I have a stored procedure that deletes duplicatesin one table:.....ASBEGINDELETE FROM mytableWHERE Id IN(SELECT Max(id)from mytablegroup by date, idsenshaving count(*) >1)ENDsometimes it happens that I have >2 rows with duplicated values.How can I write a new stored procedure that delete all rows withduplicated infomrations (leaving only one row with those values)?ThanksM.A.
View 3 Replies View RelatedI need to remove duplicate data from around 25 tables. I want to use a while loop to go through all tables. If I list out all of the column names the query runs fine, but since there are 25 tables some with 50 plus columns I was hoping to use something like the following, which errors out because my sub queries return more than one result.
SELECT q.* from
(Select ROW_NUMBER() OVER ( Partition BY (SELECT [name] AS [Name] FROM syscolumns

Suppose that I have a table that contains a lot of records that areidentical except for an id field and a date-time-stamp field. ForexampleId Unit Price DTS1 A 1.00 Date 12 A 1.00 Date 23 A 1.00 Date 34 B 1.25 Date 45 B 1.50 Date 56 B 1.50 Date 67 C 2.75 Date 78 C 2.75 Date 89 C 2.75 Date 910 C 3.00 Date 10I want to cull out records that are duplicates in the units and pricefields. I want to use the max DTS as the criteria for which record ina set of "duplicates" will remain. So, If I get the right query, Ishould return withId Unit Price DTS1 A 1.00 Date 14 B 1.25 Date 45 B 1.50 Date 57 C 2.75 Date 710 C 3.00 Date 10Is this possible using a single query? If so, how? I am sure that Ican do this using code, but it will involve a bunch of loops andprocess time. I would prefer a cleaner, more elegant way. Thanks forany help.Jerry

I know how to detect & delete dups/or >dups in test with a select clause, this works fine in a small table, but if the table has a million rows say, it sounds like a proc would be faster: my question is: How do I display those rows in a proc for detecting what the problem is. The print stmt. doesn't seem to work and I wondered if I had to go through the process of building an output stream. The proc creates okay but I'm stuck after that part.
thx

I would like the results to show:

001Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 2Â Â Â Â Â Â Â Â Â Â the count is 2 because Serial 001 has an MSDSID of 20 and 22
002Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 1Â Â Â Â Â Â Â Â Â Â Â the count is 1 because Serial 002 only has MSDSID 21
003Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 2Â Â Â Â Â Â Â Â Â Â Â the count is 2 because Serial 003 has an MSDSID of 21 and 22
004Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 1Â Â Â Â Â Â Â Â Â Â 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.
I'm trying to pull records from a source/staging table where there is a duplicate row in it.I don't need that as the requirement is to garbage in /garbage out.when I do that from mart and use joins btw fact and dimensions, Im not getting this duplicate record as Im using distinct/group by. If I removed it, then it returns more than 3000 rows which is not correct. Is there a way I can keep these duplicates without removing group by...Im using correct joins and filters.

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];

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

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.
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;
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
how i can check for duplicate entries for example if a serial number has already been inputted and a user tries to input the same serial number.. how can i get a trigger or some sort to check for duplicates and then prompt that the number has already been entered.

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.
