This is a sample of the data:

As you can see, Joe Smith has two rows, but only one of the rows is complete. I would like to delete only the row that has a NULL value in the phone and area code for Joe Smith. There are a few thousand rows that are like this. They have duplicates all but the area code and phone number.I am used to using a CTE to remove duplicates, but I am a little lost on this one. The things that I have tried, have not worked exactly as I planned.
Dear All,
I need to identify duplicate records in a table. TableA [ id, firstname, surname] I’d like to see records that may be duplicates, meaning both firstname and surname are the same and would like to know how many times they appear in the table
I’m not sure how to write this query, can someone help? Thanks in advance!
Hi guys how do you hide duplicate records, how would I do a select statement for that
In (SELECT [AccountNo] FROM [2006_CheckHistory] As Tmp GROUP BY [AccountNo] HAVING Count(*)>1 )
I have about had it with this database I have been asked to make a report out of
I am using a simple stored proc shown below which inserts a record and updates the same record field called SortID with the Primary Key Column data of the same record.Everything was working fine until few days back. The site has been deployed 2 years back and was LIVE ever since.
We have got thousands of records in this Credits table. The table field called SortID is used for moving the credits up and down.
My problem is now after 2 years of deploying the table has got duplicate records, suprisingly a same credit is appearing under different MemberID and with the same SortID.
How are these duplicate records inserted with a simple insert statement & update ??
Is this a Locking problem or Transaction problem I have no idea.
Any ideas will be of great help
Thanks in Advance
Stored Procedure Used
CREATE PROC SP_SC_INSERT (@memberID int,@title varchar(30),@dir varchar(30),@desc varchar(20))ASINSERT INTO [dbo].[Credits]([MemberID],[Title],[Director], [Description], )VALUES(@memberID,@title,@dir, @desc, )UPDATE Credits Set SortID = @@IDENTITY WHERE CreditID = @@IDENTITYGO
This is part of my trigger on table T1. I am trying to check if the records inserted to T1 is available in myDB.dbo.myTable or not (destination table). If it is available rollback T1. It does not do that although I insert the same records twice.
-- duplicate record check
SET @step = 'Duplicate record'
IF EXISTS (
SELECT i.myID, i.Type
FROM INSERTED i INNER JOIN
myDB.dbo.myTable c ON i.myID = c.myID
GROUP BY i.myID, i.Type
HAVING (COUNT(*) > 1) AND (i.Type = 'In')
)
BEGIN
ROLLBACK transaction
RAISERROR('Error: step: %s. rollback is done.', 16, 1, @step)
Return
END
What is problem?

View 2 Replies View RelatedIn order to check that a new users ID does not already exist in the database I thought it would be a good idea to put the Insert into a Try Catch statement so that I can test for the duplicate record exception and inform the user accordingly. I was also trying to avoid querying the data base before executing the Insert.
The problem is what to actually test for. When the code throws the exception it is a big long string . .
"Violation of PRIMARY KEY constraint 'PK_Users_2__51'. Cannot insert duplicate key in object 'Users'"
I just thought that there has to be something simplar to test for than comparing the exception to the above string.
Can anyone tell me of a better way of doing this ?
(by the way I am only using Web Matrix and MSDE in case it matters)

I am working on a web application that utilizes a sql server database. One of the tables is a large text file that is imported through a DTS package from a Unix server. For whatever reason, the Unix box dumps quite a few duplicate records in the nightly run and these are in turn pulled into the table. I need to get rid of these duplicates, but can't seem to get a workable solution. the query that is needed to get the records is:SELECT tblAppointments.PatientID, tblPTDEMO2.MRNumber, tblAppointments.PatientFirstName, tblAppointments.PatientLastName, tblAppointments.PatientDOB, tblAppointments.PatientSex, tblAppointments.NewPatient, tblAppointments.HomePhone, tblAppointments.WorkPhone, tblAppointments.Insurance1, tblPTDEMO2.Ins1CertNmbr, tblAppointments.Insurance2, tblPTDEMO2.Ins2CertNmbr, tblAppointments.Insurance3, tblPTDEMO2.Ins3CertNmbr, tblAppointments.ApptDate, tblAppointments.ApptTimeFROM tblAppointments CROSS JOIN tblPTDEMO2WHERE (tblAppointments.PatientID = tblPTDEMO2.MRNumber)AND tblAppointments.Insurance1 = 'MED'AND tblAppointments.ApptTypeID <> 'MTG'AND tblAppointments.ApptTypeID <> 'PNV'AND DateDiff("dd", ApptDate, GetDate()) = 0Order By tblAppointments.ApptDateMy first thought was to try to get a Select DISTINCT to work, but couldn't figure out how to do this with the query. My next thought was to try to set up constraints on the table, but, since there are duplicates, the DTS package fails. I assume there is a way to set up the transformations in a way to get this to work, but I'm not enough of an expert with SQL Server to figure this out on my own. I guess the other way to do this is to write some small script or application to do this, but I suspect there must be an easier way for those who know what they are doing. Any help on this topic would be greatly appreciated. Thanks.

So I'm working on updating and normalizing an old database, and I have some duplicate records that I can't seem to get rid of. Every column is identical, right down to what is supposed to be the key. I can't right a delete query to just isolate one row, and I can't delete (or even udpate) any row in management studio. Any thoughts on how to remove the extra rows?
There is a field that's supposed to be unique, so I can write a simple query to get all of the problem rows. The only thing is that they come back in pairs.

Hey Again,
I've been making great progress but I've hit another road block which a newbie intern like myself can't surpass. What's worse is the fact that no one is in the office today! Maybe someone can point me in the right direction with this SQL:
SELECT
r.[requestID]
,r.[requserID]
,r.[departmentID]
,CONVERT(CHAR(8),r.[submitDate],10)AS submitDate
,CONVERT(CHAR(8),r.[dueDate],10)AS dueDate
,CONVERT(CHAR(8),r.[revisedDueDate],10) AS revisedDueDate
,r.[reqStatus]
,r.[completedDate]
,d.[departmentName]
,s.[statusName]
,u.lastName + ', ' + u.firstName AS submittedBy
,ra.userID
FROMtblUserDepartment ud
INNER JOIN tblRequest rON ud.departmentID = r.departmentID
INNER JOIN tblDepartment dON r.departmentID = d.departmentID
INNER JOIN tblStatus sON r.reqStatus = s.statusID
INNER JOIN tblUser uON r.requserID = u.userID
LEFT JOIN tblRequestAssignee ra ON r.requestID = ra.requestID
WHEREud.userID= @userID
This works great except for one thing. In tblRequestAssignee, you have 1 primary assignee and can have several other assignees (that are not primary). This is denoted by a bit field "isPrimaryAssignee" in tblRequestAssignee. When I run the query, I see every request I want to but it duplicates requests with more than one assignee. What I'm trying to do is make only the primaryAssignee display if there is one. If there's not, then null is displayed (which is already happening).
Like I said, the query is mostly working right except for this duplicate record that displays when there's 2 assignees. Any help would once again be greatly appreciated.

Using Transact-SQL how can I copy all fields except one from one record to another? The field in question being the identity field. Since, this field cannot be duplicated a simple INSERT statement fails. How can I specify an exclusion list of fields?

I have the following query I am using to identify duplicate records in one of my database tables:
Code:
SELECT memberID,
COUNT(memberID) AS NumOccurrences
FROM ChapterMembers
GROUP BY memberID
HAVING ( COUNT(memberID) > 1 )
Executing the above proc returns 4079 records...
Now, I would also like to know the ChapterID for each member with a duplicate record. ChapterID is also stored in the ChapterMembers Table...
I tried running the following procedure:
Code:
SELECT memberID,
COUNT(memberID) AS NumOccurrences, chapterID
FROM ChapterMembers
GROUP BY memberID, chapterID
HAVING ( COUNT(memberID) > 1 )
But zero results are returned ...
The ultimate goal here is to identify duplicate records where one of their chapterID's = '81017' and to delete that record from the database.
Anyone have any ideas what I am doing wrong? Also, any suggestions for removing the records would be appreciated.
Thanks,
Jandrews
I am new in SQL programming world, following is query that i had created
select interfaces.nodeid as 'Node Id',
nodes.caption as 'Node Name',
netflowsources.Lasttime as NetflowLastTime
from interfaces inner join nodes on interfaces.nodeid = nodes.nodeid
inner join netflowsources on interfaces.interfaceid = netflowsources.interfaceid
where netflowsources.LastTime NOT LIKE GETDATE()
which is from that query i get a return successfully, but i just noticed that, for column nodeid was showed me multiple duplicated records, for example
nodeid value = a,a,a,b,b,c,c,c,c,d,d,d
But what i expected was to get a return without any duplicate record within it. and i also have tried using "distinct" command, but that only impacted on "a" value, but others value not change at all.

I have been given a task to locate duplicate and report duplicate records and am trying to determine the best way to do this with databases that have 1 million records plus.
Say I have a table with 20 columns, I need to check to see if 3 of 10 specific columns match.
So if 2 columns are the same its no problem however if 3 or more match, they are considered duplicate.
ex. from source the file you want to split the record into two, the one with a clean record and the other one with duplicate records
Hi, i need an opinion on this...to prevent the duplicate record in db,i am using unique constraints for a column or combination of column as the case may be.By reading this article http://aspalliance.com/687_Preventing_Duplicate_Record_Insertion_on_Page_Refresh.5 , i get the feeling that its not such a good idea..i am wondering,what does it imply?Does it mean that unique constraints are not reliable enough?Does it mean,it may break and let the duplicate record inserted,even though its not suppose to?I am using SQL server 2005
I have read Dino's article on dup recs and i have still not understood it completely.. i am looking for some not so complex ,full proof method,to prevent duplicate record insertion by clicking refresh or multiple (careless)clicking on submit....thanks ..

I am new to SQL and these forums, so please bear with me :)
My basic question is if I can create a update trigger that will pull info from another record in the same table if data in certain fields match the existing record.
An example:
The user creates a new record. If said user enters data in specified fields that matches data in the same fields in another record in the same table, can a update trigger be used to fill out the rest of this record with the data from the record that matches?
If you need more Info on my problem, ask and I will try to explain better. There may be a better way of doing this than using a trigger, but I am not sure. The fields that I would use to match the data would not be the primary key fields.
Thanks!
I have a table that "Geography" that has the following columns: city, state, zip
There are tons of duplicate cities in this table. I ran this query and it shows me the number of occurrences of each city. I want to delete all the duplicates except for 1. I don't want to do this manually as there are a lot of records.
What would the SQL look like to delete the duplicate records but keep at least one?
I have student table where duplicate student exist by name with there fathers name and mothers name. I need to search those duplicate records.
