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 '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 >

€œCannot 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?

Thanks.

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

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

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.

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

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

SQL Server 2014 :: Getting Error When Trying To Duplicate Some Code Off Of A Website?

Jan 19, 2015

I found an article on the CodeProject website named T-SQL MapReduce. I'm trying to duplicate the SQL code there into a SQL Server 2914 Developer Edition database I've got, and also the C# code using Visual Studio. I've defined the user data types fine (e.g.: word_t, words_t and so on), but I got an error when I tried to create the UDF dbo.mapper from the page. The error I got was:

Msg 102, Level 15, State 1, Procedure mapper, Line 5

Incorrect syntax near 'CALLER'.

The SQL code I used is straight off of the page; it looks like this:

[code=sql]
create function dbo.mapper(@documents DocumentsWithAutoIncrementIndexTable READONLY, @sep nvarchar)
returns @t TABLE ( wordindex int, word word_t )
WITH EXECUTE AS CALLER
[/code]

What have I done wrong? I'm guessing that the author has done something like left off a variable declaration or something like that. what am I missing?

Unique Index Conflict On Insert Into

Jun 18, 2008

I get this message when doing an insert into :

Msg 2601, Level 14, State 1, Line 1
Cannot insert duplicate key row in object 'dbo.ElementLocalCharacterised' with unique index 'ElementLocalCharacterised_uq'.
The statement has been terminated.

Now my question is : does this error mean that all inserts are done, despite those where the unique key produced a conflict? Or does it mean that none of the inserts are done (all are rejected because at least one gave a conflict) ?

If the second is the case I would like to know if it is possible to execute the insert into in a way that all inserts are done despite those that raise a conflict?

Thanks a lot for any suggestion !

How To Return Primary Unique Index Key On Insert

May 27, 2002

Hi,

I am making a program in Visual Basic .NET with SQL Server 2000.

I have a table "MyTable" with a primary key named "Id". The primary key is 'Create Unique' checked and 'Index' selected. When I insert all the fields required, except "Id" of course, I need the new record's "Id" in my VisualBasic program, but I don't know how...

I must do one of them, but don't know how either of them:

-Create a trigger on insertion that will send to the user that sended the insert command the "Id" of the record just created.

or

-get the command in Visual Basic that will send the Insert command with a return field ("Id")

Thanks in advance,

But I get the error:

Violation of PRIMARY KEY constraint 'PK_Users'. Cannot insert duplicate key in object 'dbo.Users'.

But I am using the max User_id + 1, so it can't be duplicate

This would insert about 20 records.

BULK INSERT Ignores UNIQUE Index With IGNORE_DUP_KEY Set?

All,Just want to make sure that I understand what's going on here.I have a table with IGNORE_DUP_KEY set on a unique, multi-columnindex.What I'm seeing is this:1) When performing a BULK INSERT, the UNIQUE index is not beingrespected and rows which violate the unique index are inserted.2) When performing a regular INSERT, the UNIQUE index is beingrespected and rows which violate the unique index ARE NOT inserted.Is this expected behavior.Also, I have some questions, given the index described.Q1) Will a regular INSERT that attempts to insert duplicate data getan error back or just a warning?Q2) How can I set things up so that a BULK INSERT would NOT allowduplicates to be entered into the table?Thanks,Wes Gamble

Merge Replication: Unique Index Error 1505

Mar 23, 2002

We are currently attempting to (Merge) replicate a database between 2 servers; distributor and subscriber. Apparently there are no Primary Keys in the database, and without the input of the developers, we can only assume that data integrity must be maintained by the application and the database is somewhat generic. In any case, what we are experiencing is that when we attempt to replicate, and you may know, you need PKs. Without any, SQL Server has utilized it's own (Row GUIDs). The Snapshot worked fine, but the merge agent reports error 1505.

The error is "CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID %d. Most significant primary key is '%S_KEY'."

The fix and workaround are SP2 and deselecting Unique in the index propoerties of the index raising the error. We already had SP2 on the system. Tried the other and still the same issue occurs.

Microsoft's Knowledgebase has nothing. Any suggestions or fixes would be greatly appreciated.

Regards,
Alex Cohen (MCSE, MCDBA, MCT)

SQL Server 2014 :: Getting Unique Number For Groups Of Records?

I want to generate a number that represents the groups of columns like this:

Col1 Col2 Col3 MyNumber
a b c 1
a b c 1
a b d 2
e f g 3
e f g 3

So that each grouping gets its own identifier. I've tried this:

SELECT Col1, Col2, Col3
row_number() OVER (PARTITION BY Col1, Col2, Col3
ORDER BY Col1, Col2, Col3) AS MyNumber

But I get this:

Col1 Col2 Col3 MyNumber

a b c 2
a b d 1
