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
**/

I 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.

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

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

I would like to compare rows from 2 tables.
For ex:
Table1
Col1Â Col2 Col3
1      a    aa
2     b    bb
Table2
Col1Â Col2 Col3
1       a   aa
2      b    bb
Notice Table2.Col2 first row has an extra space " a", where Table1.Col2 value is "a".I need to compare all the columns, not just 1 column (any of the column can be different). Do we use CHECKSUM for this, or is there a better way to compare the 2 tables (in this case resulted in Table2 row 1 col 2 being the difference ?

I have a table with more than 1000 records. The columns look like this
Import id  |  Reference  | Date | Username | Filename
Some of the rows are duplicates except for the fact that they have different values for the first column alone (import id)
11111     test  21-07-2015  xxxxxx  yyyyyy
22222     test  21-07-2015  xxxxxx  yyyyyy
Is it possible to delete these kind of duplicate rows by ignoring the import id ?

I have three tables, Accounts, AccountCustomer and Customers, and the data-relationshiop between are defined according to the image below:
I created also a query (the sql-query below), displaying the customers for every account that is on the table "Accounts", and I got the results, as we can see in the image below:
SELECT A.AccountID,
c.CustomerNo,
c.Surname,
c.Name,
c.TaxNum
FROM Accounts A
left join AccountCustomer ac on ac.AccountID = A.AccountID
left join Customers c on c.CustomerNo = ac.CustomerNo
order by A.AccountID;
As we understand, an "AccountID" have multiple customers, so I want to transform tha multiple results to one row, grouping by AccountID (one account belongs to one or many Customers), like the image below:
I tried to use row_number()-expression to get this, but I didn't make it. So my question is, how can I alter my sql-query to get the final result like image above?

I am interested only in Rown and Id columns. For each Rown number, I need to get the min(ID) in the second column and the duplicate ID should be in 3rd column as shown below.If i have 3 duplicate IDs , I should have 3 rows with 2nd column being the min(id) and 3rd column having one of the duplicate ids in ascending order(as shown in Rown=6)

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 am having issues trying to write a query that would provide me the unique GUID numbers associated with a distinct PID if the unique GUID's > 1. Â To summarize, I need a query that just shows which PID's have more than one unique GUID. A PID could have multiple GUID's that are the same, I'm looking for the PID's that have multiple GUID's that are different/unique.Â
Table1
GUID PID
GUID1 PID1
GUID1 PID1
GUID1 PID1
GUID2 PID1
GUID3 PID2
GUID3 PID2
GUID3 PID2
The result of the query would only have PID1 because it has two unique GUID's. PID2 would not be listed has it has the same GUID3 in each row.
Result:
PID1Â

I have the following variables VehicleID, TransactDate, TransactTime, OdometerReading, TransactCity, TransactState.
VehicleID is the unique vehicle ID, OdometerReading is the Odometer Reading, and the others are information related to the transaction time and location of the fuel card (similar to a credit card).
The records will be first grouped and sorted by VehicleID, TransactDate, TransactTime and OdometerReading. Then all records where the Vehicle ID and TransactDate is same for consecutive rows, AND TransactCity or TransactState are different for consecutive rows should be printed.
I also would like to add two derived variables.
1. Miles will be a derived variable that is the difference between consecutive odometer readings for the same Vehicle ID.
2. TimeDiff will be the second derived variable that will categorize the time difference for a particular vehicle on the same day.
My report should look like:
VehID TrDt TrTime TimeDiff Odometer Miles TrCity TrState

Hi Guys.
I have a problem. I have two feilds in a table. Both of them are (int). I want to be able make sure the same number is not put in both columns for each row. Both colums have to be a different number, and also if one is null, the other cannot be. How do I go about enforcing this policy?
For Example:
This is what I want
ID Column1 Column2
--- -------- ---------
1 5 8
2 5 7
3 null 10
4 6 2
This is what I DO NOT want:
ID Column1 Column2
--- -------- ---------
1 5 5
2 5 5
3 7 7
4 null null
I created a unique constraint between the 2 columns, but it still allows dups within the row. Please help me.

key "zip" has duplicates but the rows are unique.
How do I filter out only the duplicate zips. So in effect I only have one row per unique key.
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 )

Duncan, I tried this but it does not return one row per key.

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?

I'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.

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?

Just recently I noticed something that I consider very strange on a SQL7.0 server with SP1.
In [Server -> Management -> Current Activity -> Process Info] I see a great number of rows(connections) around 70 or so that all have the same net_address value. However, the nt_loginame is different on each.
Q1: How can this be?
Q2: Isn't the net_address really the MAC of the network card?
Also, on a test SQL7.0 server with SP1 where the connections are far less (around 15 or so), I noticed the same problem. Luckily, because the connection count is low I was able to go around to each machine where the nt_loginame was used to log on and found that the net_address shown in [Current Acivity] didn't match any of these machines. Why?

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)

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(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.
STUDENT_ID| ACAD LEVEL |Â GENDER |
PROG_DESCÂ | RACEETHNICITY |

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.

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:

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?

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),

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

I want to compare the tables using first name, and I have a log variable which I want to have the value as per the differences in the table that is if the first name matches and second name and dob dont match it shows log value for that FN as 'LN and DOB dont match'.
similarly if First name matches and dob matches then @log is 'LN not match'.
And in case all three match it should show 'match'as log value.The query I use is a s follows:-
Code:
USE testing
GO
DECLARE @NR int
DECLARE @log varchar(200)
SELECT @NR = COUNT(*) FROM a
WHILE @NR>0
[code]...
the result I am getting is :-
Code:
fnlndob (No column name)
