Hi everybody couldn't get through with saving my data on the table with two primary keys...
my table structure is this
pubidintUnchecked (primary key)
pubchar(1)Unchecked
publchar(1)Unchecked
pubcodechar(2)Unchecked (primary key)
a sample data is here
pubid pub publ pubcode
1 a b ab
1 b b bb
2 a b ab
2 b b bb
when i save this table modifying the pubid and pubcode as primary keys the following error displays...
Unable to create index 'PK_PUBS3'.
CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 1. Most significant primary key is '51'.
Could not create constraint. See previous errors.
The statement has been terminated.
what i understand is that on the primary key duplicates are not allowed how could i allow it?
thanks
Hi,
I want to know the different sources, mediums and ways using which the duplicate recoprds or adta can make an entry in our database tables. I found 4 ways for this from many articles on net that are as follows:
Duplicate data might arrive at your database via an interface to another system
Data is loaded into table from other sources because during data loads, the integrity constraints are disabled
Merging data from disparate systems
Inheriting a poorly designed databaseBut is there any other ways also present????? Please tell me???
Thanks,
Hi,i am using SQL server 2005 and have a table with 4 columns.Column1 is primary key,col2 is foreign key and col3 and col4 are regular data column.When the user enters the data i want to make sure that for a given foreign key(col2),entries in col3 are not duplicated.Is there a way,i can make sure this at db level,using some kind of constraints or something?Thanks a bunch..
View 10 Replies View RelatedWe have a SQL Server 6.5 table, with composite Primary Key, having the Duplicate Entry for the Key. I wonder how it got entered there? Now when we are trying to import this table to SQL2K, it's failing with Duplicate row error. Any Help?
View 4 Replies View RelatedI'm trying to modify a specific row in a table.
$paper_id = 2A
$query = "UPDATE book SET paper_id='$paper_id', title='$title'";
I'm getting this error <<query failed: Duplicate entry '2A' for key 'PRIMARY'>>
Structure:
Column: paper_id
Type: Char
Length: 20
Deafult: None
I am wanting to create a query so that I can combine each of the found duplicates into one entry.
An example of this is:
Name |ID |Tag |Address |carNum
-------------------------------------------------------
Bob Barker |2054| 52377 |235 Some road |9874
Bill Gates |5630| 69471 |014 Washington Rd. |3700
Bob Barker |2054| 97011 |235 Some road |9874
Bob Barker |2054| 40019 |235 Some road |9874
Steve Jobs |8501| 73051 |100 Infinity St. |4901
John Doe |7149| 86740 |7105 Bull Rd. |9282
Bill Gates |5630| 55970 |014 Washington Rd. |3700
Tim Boons |6370| 60701 |852 Mnt. Creek Rd. |7059
In the example above, Bob Barker and Bill gates are both in the database more than once so I would like the output to be the following:
Bob Barker |2054|52377/97011/40019|235 Some road |9874
Bill Gates |5630|69471/55970 |014 Washington Rd.|3700
Steve Jobs |8501|73051 |100 Infinity St. |4901
John Doe |7149|86740 |7105 Bull Rd. |9282
Tim Boons |6370|60701 |852 Mnt. Creek Rd. |7059
Notice how Bob Barker & Bill Gates appends the tag row (the duplicated data) into one row instead of having multiple rows. This is because I do not want to have to check the previous ID and see if it matches the current id and append to the data.
I have tested the code below to remove duplicate table entries based on the field IntOOS. This code works; however, I want to ensure I am removing the oldest entries and keeping the most recent entry. The field to key on this would be something like Max(ID). What would be the best way to ensure I keep the most recent table entry?

View 1 Replies View RelatedHello All,
I am using the Web Site Administration Tool with the ASP.NET login controls to create/manage user logins & roles for my site.
I have exported the ASPNETDB.MDF into my SQL Database ready to use with my app. The problem that I'm having is that whenever I add a user, using either the Web Site Administration Tool or the Classes available in the code-behind. The entry is doubled up in the database.
This is not a problem when logging on....however, when it comes to deleting a user it will only take one of the entries out and leave the duplicate in there. So if the administrator has deleted a user from the app and then tried to create another one with the same UserName (Which whomever is well within his/her rights to be able to do), they cannot because the entry which has "stay behind" in the database conflicts with the entry.
Any help on this matter would be greatly apprieciated. If any more info on this matter is required please ask (It was quite hard to try and explain this :-)

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
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 ?

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.

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.
