Jan 25, 2000I have a large table that consists of the columns zip, state, city, county. The primary key "zip" has duplicates but the rows are unique.
How do I filter out only the duplicate zips.

View 1 Replies View RelatedUnique Index Returns Duplicate Rows
Oct 25, 2004We 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

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?

Transact SQL :: How To Compare Duplicate Rows Within A Unique Process
Nov 9, 2015We 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

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
Delete Rows With Duplicate Column Data But Unique Row Data
May 25, 2000Hello,
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

Randy Garland
if you just want a list of all rows with duplicate zipcodes then ...
SELECT * FROM TableName WHERE zip IN ( SELECT zip FROM TableName
GROUP BY zip HAVING COUNT(*)>1 )

Renaming Duplicate Row Data To Be Unique?
Sep 22, 2004I 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?
Oct 25, 2013I'm designing an app for stock keeping. In my DB, I have a field called "ItemSerialNo" and I made it unique(but not the table's primary key). 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:
1. ITEM SERIAL NO = 12345
BRAND NAME = AA
2. ITEM SERIAL NO = 12345
BRAND NAME = BB.

Unique Constraint Does Not Permit Duplicate NULL Values
Oct 2, 2000After 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, 2015I 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(Â
 COUNTROWS( Table1 );Â
 FILTER( Table1;  [Column1] = EARLIER( [Column1] ) && [Column2]
= EARLIER( [Column2]
) )Â
 ) > 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.

Cannot Insert Duplicate Key Row In Object 'dbo.lastlogin' With Unique Index 'IX_lastlogin'.
Aug 22, 2007Hi.
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.

SQL Server 2014 :: Error On Unique Index - Duplicate Key When Insert / Select
Aug 4, 2014I 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.

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.

Getting Unique Rows
Jun 15, 2004Is it possible to use the DISTINCT clause on just one field in the SELECT statement?
The following SQL statement causes an error:
SELECT DISTINCT appt.ref, appt.notes FROM Appointments appt
...because DISTINCT can't be used on the notes field as it of type 'text'.
How can I focus the DISTINCT keyword on just the ref field?
(I know ref is the primary key, so this example wouldn't need the DISTINCT keyword, but I've simplified a much more complex statement)

Pls.Note: It should not return BetId 501 in the result, since it belongs to different combination(108,109,110).
Similarly if i give, select criteria where game id =(108,109,110) it should return
BetId 501.not the 500 and 502..which is different combination..
Hope i clarified my problem..pls help me in this regard.Thanks a lot...

Duplicate Rows
May 16, 2007Hi. I'm a SQL Server newbie, very experienced with Access, developing an ASP.NET database editor web app. I query the database with a statement more or less in the following form:
SELECT organisation.OrgID, organisation.Name, organisation.whatever FROM services INNER JOIN servicegrouping ON services.serviceID=servicegrouping.serviceID INNER JOIN organisations ON servicegrouping.OrgID = organisations.OrgID WHERE services.service=x OR services.service=y
In other words, I have a database of organisations. The services offered by the organisations are in a separate table, and I only want to return organisations that offer services X or Y.
Okay, now if I did this in Access, this query would return just one record for each organisation that meets the condition, unless I was to include a field from the services table in the SELECT clause, in which case of course I would get one record for each organisation and unique service offered.
But in MS SQL, the query returns duplicate rows if there is more than service offered by the organisation that meets the WHERE condition (=x or =y). Why is this and what do I need to do to my SQL statement to ensure I only get unique rows?

Mar 20, 2008I got the following query:SELECT TOP (8) ext.extID, ext.Quote, ext.sourceTitle, ext.extRating, gf_game.gameID, gf_game.catID, gf_game.URL, gf_game.TitleFROM gf_game_ext AS ext INNER JOIN gf_game ON gf_game.gameID = ext.gameIDWHERE (ext.Approved = 1)ORDER BY ext.extID DESC which is e.g. producing this output: 6000 -some text- Title 90 1960 2 tom-cl tom cl5999 -some text- title 90 1960 2 tom-clcl asdf5998 -some text- title 90 1959 2 tom-cl-cl asdfWhat I'd like to do now is to filter out the duplicate GameIDs (= 1960) so that just one unique row with the gameid 1960 is remaining. If I put in a SELECT DINSTINCT TOP(8) it just counts for the table ext, but I need it to count for gf_game.gameID - is that possible?Thanks a lot!

May 17, 2007Using DISTINCT with SELECT have effect only for one column.
But when is needed to select (or to count) queries for all rows for all columns in a table without duplicates, doesn't work.
Select DISTINCT a1,a2,a3,a4 From Y ---> results 167 rows
Select DISTINCT a4 From Y ---> " 85 rows
Any thoughts?
