Duplicate Record Problem

Nov 4, 2005

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.

Duplicate Record Trigger

Nov 24, 2006

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?

Duplicate Record Question

May 4, 2004

In 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)

Duplicate Record Problem

Apr 23, 2008

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.

Eliminate Duplicate Record(s)?

Jun 22, 2007

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.

Help Selecting Duplicate Record Details

Oct 10, 2006

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

Filtering Multiple Duplicate Record

May 2, 2014

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.

So if 2 columns are the same its no problem however if 3 or more match, they are considered duplicate.

Opinion On Preventing Duplicate Record Insertion

Oct 26, 2007

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 ..

Duplicate A Record Using Update Trigger Question

Jun 1, 2006

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!

How Do I Select The Maximum Date For Each Record Having Duplicate ID

Dec 19, 2007



Hi All,
Here is my story, how to change a column called Flag_Status based on the maximum Updated date. i.e. i want to make Flag_Status be 1 for the records which have maximum Updated_date (current record) and the rest to make it 0. for example accountID 1 has three records updated, but only one is current the rest are historical, thus i want the history record to be Falg_status 0 and the current record be 1. Note that Inserted_Date and Updated_Date are created using SSIS Derived column During loading the source table, it helps me when each record is inserted into the Data warehouse.

Here is My source table Name: Source_table,


CREATE TABLE dbo.Source_table

(

AccountID INT PRIMARY KEY,

Price int,

Address varchar(30),

added DATETIME DEFAULT GETDATE(),

edited DATETIME DEFAULT GETDATE(),

Flag_Status Int Default 1

)

GO

Here is the Fact_table


CREATE TABLE dbo.Fact_table

(

Fact_table_Key Int Identity (1, 1) NOT NULL,

AccountID INT,

Price INT,

Address varchar(30),

added DATETIME DEFAULT GETDATE(),

edited DATETIME DEFAULT GETDATE(),

editor VARCHAR(64),

Flag_Status Int Default 1,

Inserted_Date DATETIME DEFAULT GETDATE(),

Updated_Date DATETIME DEFAULT GETDATE()

)

GO

Source_table:

AccountID Price Address added edited Flag_Status
---------------- --------- ------------- ----------- ------------- ------------------
1 10 xyz 01-2006 01-2006 1
2 14 abc 02-2006 02-2006 1
3 13 mno 03-2006 03-2006 1

Here is the fact table, table name= Fact_table



Fact_table_Key AccountID Price Address added edited Flag_Status Inserted_Date Updated_Date
-------------------- ------------- --------- ------------ ------- --------- ---------------- ------------------ -------------------
1 1 10 xyz 01-2006 01-2006 1 05-2006 NULL
2 2 14 abc 02-2006 02-2006 1 05-2006 NULL
3 3 13 mno 03-2006 03-2006 1 05-2006 NULL
4 1 17 ght 01-2006 06-2006 1 NULL 08-2006
5 2 18 dmc 02-2006 07-2006 1 NULL 08-2006
6 3 20 kmc 03-2006 09-2006 1 NULL 10-2006
7 1 19 xyz 01-2006 11-2006 1 NULL 12-2006
8 2 19 klm 02-2006 01-2007 1 NULL 02-2007
9 3 21 pqr 03-2006 03-2007 1 NULL 04-2007

Here is what i am thinking: But it gives me Wrong Flag_Status.


UPDATE Fact_table

SET Flag_Status =


CASE


WHEN (SELECT Max(Updated_Date) From Fact_table

WHERE AccountID IN (SELECT AccountID FROM Fact_table

Group By AccountID Having Count(AccountID)>1)) >

(SELECT Max(edited) From Source_table

WHERE Flag_Status = 1)

THEN 1


WHEN (SELECT AccountID From Source_table

Group By AccountID

Having Count(AccountID) =1) =

(SELECT AccountID From Fact_table

WHERE Updated_Date IS NULL)

THEN 1

ELSE 0

END

Transact SQL :: Query Is Trying To Insert Duplicate Record?
