Unique Index Returns Duplicate Rows

Oct 25, 2004

We are running the following query, which has a unique index on Table_2 (col1 and sys1), and Column col1 from Table_1 is unique.

select top 100 s.*, x.col1
from Table_1 s
left outer join Table_2 x
on x.col1 = s.col1 and x.sys1 = 'SYSTEM0'

Unfortunately this query returns duplicate rows. And every time the result is different

But once we dbcc dbreindex the unique index on Table_2, the result will not have any dups.

Any ideas?

Thanks

Update Rows To Resolve Issues About Duplicate Keys On Create Unique Index

May 7, 2008

Hi there ...here comes a tricky one.

I have a database table which needs to make the Index "ParentREF, UniqueName" unique - but this fails because duplicate keys are found. Thus I now need to cleanup these duplicate rows - but I cannot just delete the duplicates, because they might have rows in detail tables.
This means that all duplicate rows needs an update on the "UniqueName" value - but not the first (valid) one!

I can find those rows by

SELECT OID, UniqueName, ParentREF, CreatedUTC, ModifiedUTC FROM dbo.CmsContent AS table0
WHERE EXISTS (
SELECT OID, UniqueName, ParentREF FROM dbo.CmsContent AS table1
WHERE table0.ParentREF = table1.ParentREF
AND table0.UniqueName = table1.UniqueName
AND table0.OID != table1.OID
)
ORDER BY ParentREF, UniqueName, ModifiedUTC desc

...but I struggle to make the required SQL (SP?) to update the "invalid" rows.
Note: the "valid" row is the one with the newest ModifiedUTC value - this row must kept unchanged!

ATM the preferred (cause easiest) way is to rename the invalid rows with
UniqueName = OID
because if I use any other name I risk to create another double entry.

Thanks in advance to whoever can help me

Integration Services :: Duplicate Key Row With Unique Index

Oct 2, 2015

I have a look up table with old data, which i need to truncate and load with the new set of data, however when loading I'm getting the following error

[OLE DB Destination [32]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred.
Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80004005
Description: "Cannot insert duplicate key row in object 'dbo.CaseType' with unique index 'idx_CaseType'. The duplicate key value is (49, AH).".

I know , what it means that since CaseType column has a unique index we cannot insert duplicate key, but in real world the scenarios are different , the record in question is as follows: so what is the workaround in this kind of scenario other than making it Non-unique Index?

CaseTypeID CountyID CaseCategory CaseTypeCode CaseTypeName

Cannot Insert Duplicate Key Row In Object 'MSmerge_genhistory' With Unique Index 'unc1MSmerge_genhistory'

Feb 28, 2007

I have 1 client who keeps running into the following error on the subscriber and merge agents >

��Cannot insert duplicate key row in object 'MSmerge_genhistory' with unique index 'unc1MSmerge_genhistory'.�?

Last time we got this error I ran a reindex on table MSmerge_genhistory on the publisher database, I then successfully generated a new snapshot and the subscribers started to synchronize again. This time around I keep getting the error even after I follow these steps (I also ran all the jobs to clean up replication). The last time I ran into this error I created a job to reindex msmerge_genhistory on a nightly bases in an effort to avoid this problem. Can somebody please provide me with a workaround and also the reason why this error occurs in the first place.

Thank you in advanced,

Cannot Insert Duplicate Key Row In Object 'dbo.lastlogin' With Unique Index 'IX_lastlogin'.

Aug 22, 2007

Hi.

I have been recently redesigning my tables - creating FK
relationships from child tables to the PK userid in the Users table.
The specifics of what I did and why can be seen here:

http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1968856&SiteID=1

But, now I am getting the below error:

Cannot insert duplicate key row in object 'dbo.lastlogin' with unique index 'IX_lastlogin'.
The statement has been terminated.

Or, for that matter, SavedSearches or any other table where I need to
insert the same userid twice. I can see why I would want to avoid duplicates in the Users table. But, for lastlogin, savedsearches, and
a few of my other tables, the same user may account for multiple rows.

Any suggestions as to where I messed up and how to deal with this?

SQL Server 2014 :: Error On Unique Index - Duplicate Key When Insert / Select

Aug 4, 2014

I have an issue where I am getting an error on an unique index.

I know why I am getting the error but not sure how to get around it.

The query does a check on whether a unique value exists in the Insert/Select. If I run it one record at a time (SELECT TOP 1...) it works fine and just won't update it if the record exists.

But if I do it in a batch, I get the error. I assume this is because it does the checking on the file before records are written out and then writes out the records one at a time from a temporary table.

It thinks all the records are unique because it compares the records one at a time to the original table (where there would be no duplicates). But it doesn't check the records against each other. Then when it actually writes out the record, the duplicate is there.

How do I do a batch where the Insert/Select would write out the records without the duplicates as it does when I do it one record at a time.

CREATE TABLE #TestTable
(
Name varchar(50),
Email varchar (40)
)
Insert #TestTable (Name,Email) Values('Tom', 'tom@aol.com')

Cannot Insert Duplicate Key Row In Object 'dbo.blabla..' With Unique Index 'Idx_blablabl'. The Statement Has Been Terminated. At

Jan 16, 2007

We are developing a project that is expected to hold TB of data and the back end used is SQL Server 2005.

I have the following problem

I have applied Nonclustered index over a column on a table.

Designed a SP for insertion which caters for updation incase the criteria based on the input is met.

The logic goes like this

Incase there exists a row containing the value of the column that is indexed for uniqueness, there should be updation. If not there should be a new row created.

However often there is an error message that is placed above. This happens only on some of the SPs and only on rare occasions.

Can any body tell me if there is any problem with the SQL Server 2005

Thanks in advance

Transact SQL :: How To Compare Duplicate Rows Within A Unique Process

Nov 9, 2015

We write to a log file each time a job runs. We give each job a unique batchid. I want to compare the run times of each step/record between two batch ids: '20150101888' and '20150101777'. Column Mins in the number of minutes each step ran. I am having trouble comparing the rows that have generic process and stepname – Trans Switch in this example. A new process within a batchid starts with a 'XX', 'Load'.

So I want to compare CA's Trans to CA's Tran Switch and ER's Trans Switch to ER's, etc. There can be multiple Trans Switch per process. There should be the same number between each batch, but no guarantees that something might change. Also, Trans Switch is not the record right after the new process (CA, ER) in production.

I have just made a very simplified example.

/**
Want to compare 20150101888 to 20150101777 and end up with this result set. Notice that the duplicate process/step within a process has the process (CA and ER in this example) and a sequential number added to it: 'CA Trans 1'. Need this to pull out the largest time differences.

Time difference, process, step, mins1, mins2, batchid1, batchid2
-6, CA, Load, 17, 23, 20150101888, 20150101777
0, CA Trans 1, Switch, 8, 8, 20150101888, 20150101777
-6, CA Trans 2, Switch, 9, 15, 20150101888, 20150101777
-4, ER, Load, 7, 11, 20150101888, 20150101777
-4, ER Trans 1, Switch, 7, 11, 20150101888, 20150101777

Delete Rows With Duplicate Column Data But Unique Row Data

May 25, 2000

Hello,

This probably has been addressed before but I was unable to get the search to work properly on this site.
I am needing a script/way of deleting all rows from a DB with the exception of one record left for each row that has duplicate column data. Example :
Row 1
Field1 = 12345 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Row 2
Field1 = 12345 Field2 =zzzzzz Field 3=xxxxxx Field4=yyyyyy etc.
Row3
Field1 = 12345 Field2 =20202 Field 3=11111 Field4=zzzzz etc.
Row 4
Field1 = 54321 Field2 =xxxxx Field 3=yyyyy Field4=zzzzz etc.
Etc. Etc.

I want to be able to find the duplicates for Field1 and then delete all but 1 of those rows.( I don't care which one I keep just so only one is left.) The data in the other fields may or may not be unique.

I know how to find the duplicates it's just the deleting part I am having problems with. Any help would be much appreciated. Thanks,

Kerry

I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?

Which one do one use ?

Do I Need To Verify That NewID() Returns A Unique GUID?

I'm migrating a web based system to SQL server. I'm planning on using the SQL server function NewID() to create unique keys for many of my records in many different tables. I'm just wondering if NewID() is guaranteed to return a value that does not already exist in my database. I mean obviously once you have a certain number of records (a hell of a lot) you'd be breaking the odds to never come up with a duplicate. Do I need to make sure the result of NEWID() doesn't already exist?Thanks

Renaming Duplicate Row Data To Be Unique?

Sep 22, 2004

I just converted an old non-relational database into something that MS SQL likes. The old primary keys were broken up into two columns, one being useful. The column I need to use has some rows with the same values in them.

I am looking for some way in a SQL script to look for the duplicate rows and add "_X" to the data where X is a value incremented by 1 for each duplicate row found.

For example, 3 duplicate rows with "5443aa" would return "5443aa", "5443aa_1","5443aa_2".

Any ideas?

Duplicate Data For Unique Fields With Different Name?

On my front end, I have a text box for Item Serial No and a combo box loaded with the item brands and also a save button. I know that if I try to save a serial no already existing in my DB, the app won't allow me because of the unique property of the field named "ItemSerialNo". But I want to be able to save a serial no already existing in my DB but with a different brand name.

For example, I want to be able to save information like:

BRAND NAME = AA
2. ITEM SERIAL NO = 12345

Unique Constraint Does Not Permit Duplicate NULL Values

Oct 2, 2000

After adding a Unique constraint to a database I cannot add more than one record with a null value for the constrained field. I've tried both adding the constraint to an empty table as well as a table with multiple null values already in the subject field; both efforts have failed.

According to BOL SQL-7 allows Unique Constraints on fields with Null values. Am I missing a step? I do need to allow nulls in the field yet ensure that when there is a non-null value it is unique.

The SQL statement I've used is: ALTER TABLE tbl_MasterUIC ADD CONSTRAINT uniquesamplenbr UNIQUE NONCLUSTERED (samplenbr)

Power Pivot :: How To Flag Unique And Duplicate Records (DAX)

Oct 26, 2015

I am trying to find duplicate records based on a set of criteria, and flag one of those records as unique and the other duplicate ones as dup.

I found this suggestion:

IF( CALCULATE(
COUNTROWS( Table1 );
FILTER( Table1; [Column1] = EARLIER( [Column1] ) && [Column2]
= EARLIER( [Column2]
) )
) > 1;
"dup";
"unique"
)

However, this method flags all duplicates as dup. how I can get to the enclosed results for one particular student?The dup check column shows the desired results. The criterion is any record with the same STUDENT_ID, PROG_DESC, FISCAL_YEAR will be considered as duplicates, but should at least have one record out of that group of duplicates flagged as 1.

STUDENT_ID| ACAD LEVEL | GENDER |
PROG_DESC | RACEETHNICITY |
