I have a table storing only 2 FKs, let's say PID, MID
Is there any way that I can check distinct data before row is added to this table?
For example, current data is
PID MID------------100 2001100 2005101 3002102 1009102 7523102 2449
If my query is about to insert PID 100, MID 2001, since it's existing data, i don't want to add it. Can I use trigger to solve this issue?
Thanks.
I have an ASP.Net Web appplication with a Back-End SQL DB. There are 3 Tables; Users, Groups, and GroupMember.
The GroupMember table is used to link Users to Groups and consists of just two fields; userID and GroupID.
Here is a sample of some data:
User1 Group1
User1 Group2
User2 Group2
User3 Group1
User3 Group3
Users can belong to multiple Groups. However, you shouldn't be able to have the same user and group comobination more than once. for example:
User1 Group1
User2 Group2
User1 Group1
I can stop this kind of duplicate data entry by doing a lookup first (using asp.net) to see if the entry already exists but this seems cumbersome.
Is there a simpler way to prevent duplicate entries in a table using sql?
Thanks a lot,
Chris
Hi,I need to enforce that a table does not have "duplicates" for aspecific status type in the table.If the column "STATUS" = 2, then there can not be more than one rowwith a specific "ID" column.I can not use a unique key constraint because duplicate values for thiscombo of columns is valid for the status = 1.Just when the status = 2, there can not be any other rows with the sameID and status = 2.Any ideas?-Paul

Hi,
I've got a table containing calculated values, so i created a field named "archived" (bit datatype) on this table, to prevent the values to be updated if this field is set to true.
Is it possible to created a constraint, to prevent the row to be updated if ARCHIVED=true ? How can i do it ?

View 2 Replies View RelatedI am using SQL Server 2000. I have a table (tbDupes) with duplicate records. I want to populate another table (tbUnique) with unique records.
My tbDupes has about 50 columns and three of them make up my primary key in tbUnique. I thought I could get unique records by using the following SQL statement.
Code Snippet
INSERT INTO tbUnique
SELECT * FROM tbDupes
I received this error: Cannot insert duplicate key
Is there a database setting that will allow me to insert the first record and prevent any duplicates from being inserted? I thought this was the default behavior and think that maybe the DBA changed it.
I know I can achieve this by creating a cursor with tbDupes and then something like "IF NOT EXISTS(...) THEN INSERT". However, I would prefer to avoid using a cursor.
We have an issue that our SQL Replication between our Application Server (holding 13 months of data) and our Reporting Server (holding 5-6 years of data).
Both systems are running on NT4, SQL Server 7 Ent SP3.
Our issue is that we used to run SQL Replication but then stopped using it, and used another method of replicating our data from the App Svr to Rpt Svr. However, we have now been told that we have to use SQL Replication.
We set it up as usual, but when the log reader starts up, it finds the 1st transaction and moves it into the distribution database, but it then fails when attempting to do the 2nd transaction with the error "Cannot insert duplicate key row in object MSrepl_transactions with unique index ucMSrepl_transactions.
We have checked the tables in the publisher db and they don't hold any duplicates, so I can only assume the key it is talking about is the key field in the distribution database, but this is a Binary field which I believe is populated by replication itself!! Is this correct?
If so, why is it trying to enter duplicates? And can we resync replication to fix it?
Hi, I need to insert rows into table1 from table2 and table3 but I don't want to insert repeated combinations of col2, col3. So, table1 has the primary key col2, col3.
This the table1:
create table table1(
col1 int not null,
col2 int not null,
col3 int not null,
constraint PK_table1 primary key (col2, col3)
)
This is my "insert" code:
INSERT INTO table1
SELECT table2.col1,table2.col2, table3.col3
FROM table2, table3
WHERE table2.col1 = table3.col1
Wich conditions shoud i add to this code?
Thanks.

The following quote is the exact error message that I get when I attempt to create a pull subscription. The STAppointment is one of a 15 databases that need to replicate inorder for the application SalonTouch to run properly.
What is causing this error? Is it user rights? Is it a problem with sql2005? Am I missing a step? Is there a problem with the database I am working with? What else?

I deliberately intend to add some duplicates to one of my tables. For eg
Job User IsAdmin
JobID 235User ID 1
JobID 235User ID 5
JobID 235User ID 9
JobID 235User ID 5
JobID 235User ID 2
JobID 235User ID 9
JobID 235User ID 10
JobID 235User ID 1
I know its bad practice to do such a thing but there is a genuine reason. What I need to do is to be able to have a SQL statement that appends true to the IsAdmin field whenever it encounters the next UserID thats happens to be a duplicate. Hence the above would look like:
Job User IsAdmin
JobID 235User ID 1
JobID 235User ID 5
JobID 235User ID 9
JobID 235User ID 5 True
JobID 235User ID 2
JobID 235User ID 9 True
JobID 235User ID 10
JobID 235User ID 1 True
Thanks
I ought to know how to do this, but it escapes me at the moment. I need to write an insert statement for a table that will be based on a complex select query. The select query may return rows that are already in the target table. In that case, I don't want duplicates created, but I don't want the query to error, either. I can't remember how to set that up.
View 3 Replies View RelatedI have a table using an identity column as its Primary Key and twocolumns (table reduced for simplicity) EmployeeNumber and ArrivalTime.CREATE TABLE [tblRecords] ([ID] [bigint] IDENTITY (1, 1) NOT NULL ,[EmployeeNumber] [varchar] (10) COLLATE SQL_Latin1_General_CP1_CI_ASNOT NULL ,[ArrivalTime] [datetime] NOT NULL ,CONSTRAINT [PK_tblRecords] PRIMARY KEY CLUSTERED([ID]) ON [PRIMARY]) ON [PRIMARY]GOI have an insert procedure that checks for duplicates before insertinga new record:IF (SELECT TOP 1 [ID] FROM tblRecords WHERE EmployeeNumber =@SocialSecurity) IS NULLBEGININSERT INTO tblRecords(EmployeeNumber,ArrivalTime)VALUES (@EmployeeNumber, @ArrivalTime)SELECT SCOPE_IDENTITY()ENDELSESELECT 0 AS DuplicateRecordIn 99.9% of the cases, this works well. However, in the event that theinsert attempts are literally "ticks" apart, the "SELECT TOP 1..."command completes on both attempts before the first attempt completes.So I end up with duplicate entries if the procedure is called multipletimes vey quickly. The system needs to prevent duplicateEmployeeNumbers within the past 45 days so setting the EmployeeNumberto UNIQUE would not work. I can check for older entries (45 days ornewer) very easily, but I do not know how to handle the times when theprocedure is called multiple times within milliseconds. Would aTRANSACTION with a duplicate check after the INSERT with a ROLLBACKwork in this case? Any help is greatly appreciated!-E

Hi All, I have a web form that inserts information into two tables in sql 2005 database on a submit button click. I have a unique key on the tables preventing duplicate information which works fine. The problem I have is that at the minute if a users tries to insert a duplicate row they just get the built in sql error message. Is there a way I can validate the information before if goes into the database and display perhaps a label telling the user of their error or is there a way I can customize the build in sql error message? I've had a search on various forums and sites and can't find any info that would help me. Thanks in advance

I have a SQL Server 2008 R2 on a windows 2008 server.After one failed backup, I started getting these errors:
Error: 2601, Severity: 14, State: 1.Cannot insert duplicate key row in object 'sys.syscommittab' with unique index 'si_xdes_id'.
Error: 3999, Severity: 17, State: 1.Failed to flush the commit table to disk in dbid 5 due to error 2601. Check the errorlog for more information.
From Microsoft, I found this:

But this bug refers to SQL Server 2008. What should I do if in my case is a R2 version?
This is like the bug from hell. It is kind of hard to explain, soplease bear with me.Background Info: SQL Server 7.0, on an NT box, Active Server pageswith Javascript, using ADO objects.I'm inserting simple records into a table. But one insert command isplacing 2 or 3 records into the table. The 'extra' records, have thesame data as the previous insert incident, (except for the timestamp).Here is an example. Follow the values of the 'Search String' field:I inserted one record at a time, in the following order (And only oneinsert per item):airplanejetdogcatmousetigerAfter this, I should have had 6 records in the table.

Then, when I inserted the 'cat' record, another'dog' record was inserted. I waited awhile, and inserted mouse, andonly the mouse was inserted. But soon after, I inserted 'tiger', and 2more mouse records were inserted.If I wait awhile between inserts, then no extra records are inserted.( Notice 'airplane', and the first 'mouse' entries. ) But if I insertrecords right after one another, then the second record insertion alsoinserts a record with data from the 1st insertion.Here is the complete function, in Javascript (The main code ofinterestmay start at the Query = "INSERT ... statement):----------------------------------------------------------------------//Write SearchTrack Record ------------------------------------Search.prototype.writeSearchTrackRec = function(){Response.Write ("<br>Calling function writeSearchTrack "); // fordebugvar Query;var vid;var type = "i"; // Type is imagevar Q = "', '";var datetime = "GETDATE()";//Get the Vid// First - try to get from the outVid var of Cookieinctry{vid = outVid;}catch(e){vid = Request.Cookies("CGIVid"); // Gets cookie id valuevid = ""+vid;if (vid == 'undefined' || vid == ""){vid = "ImageSearchNoVid";}}try{Query = "INSERT SearchTrack (Vid, Type, SearchString, DateTime,NumResults) ";Query += "VALUES ('"+vid+Q+type+Q+this.searchString+"',"+datetime+","+this.numResults+ ")";this.cmd.CommandText = Query;this.cmd.Execute();}catch(e){writeGenericErrLog("Insert SearchTrack failed", "Vid: "+vid+"- SearchString:: "+this.searchString+" - NumResults: "+this.numResults, e.description);}}//end-----------------------------------------------------------------I also wrote a non-object oriented function, and created the commandobject inside the function.

I guess there is first for everything...I had never seen error like this before
Violation of PRIMARY KEY constraint 'PK_table1'. Cannot insert duplicate key in object 'table1'. The statement has been terminated.
In this case Primary Key is Identity column. I do not include Idenity column in Insert statement.
Incidently SQL server machines had cluster failure couple of days before. I am not sure whether it has anything to do with it.

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

One of my database transaction log backup jobs failed this morning, although the log backup was still taken, the job reported failure. The job has run successfully a number of times since. The job reported a primary key violation error on the msdb.dbo.backupmediaset table. The full error message was
Violation of PRIMARY KEY constraint 'PK__backupme__DAC69E4D599F1693'. Cannot insert duplicate key in object 'dbo.backupmediaset'. The duplicate key value is (401862).
Msg 3009, Level 16, State 1, Server myservername, Line 1
Could not insert a backup or restore history/detail record in the msdb database. This may indicate a problem with the msdb database. The backup/restore operation was still successful.
After investigating the backupset and backupmediaset tables in msdb I can see that value used for the failed insert was used previously for the last database log backup in the previous log backup run. The failure was reported for the first database log backup attempted. The SQL Log shows an entry for the log being backed up successfully.
I have checked the identify value in the backupmediaset table using DBCC CHECKIDENT and all looks OK.
DBCC CHECKIDENT ('backupmediaset',NORESEED)
Is there anything else I need to check?
Does sql server have a way to handle errors in a sproc which would allowone to insert rows, ignoring rows which would create a duplicate keyviolation? I know if one loops one can handle the error on a row by rowbasis. But is there a way to skip the loop and do it as a bulk insert?It's easy to do in Access, but I'm curious to know if SQL Server propercan handle like this. I am guessing that a looping operation would beslower to execute?

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).
