Key Violation During Synchronization
Sep 10, 2006
Dear Friends
I restored same database in Publisher & subscriber.If I want to apply Transactional replication I have to apply initial snapshot.then I am getting key-violation problems during initialization .Some times Primary key table will be dropped before foreign key table.sometimes it won't able to drop some indexes.This I am getting if I am going for all tables of database.But here i need all tables.If I am going for selective table I don't have any problem.For avoiding this problem I tried all the options in table article option in publication wizard.But some na some key violation I am getting always.So please give me some better suggestion
Thanks in Advance

Hello everybody,
There is some strange behaviour i've recently noticed while watching synchronization progress in Replication Monitor on SQL 2005 Server Standard with merge replication configured. The merge process seems to repeat several times.
This is the initial synchronizaion (reinitalization at the subsciber). Client is using Microsoft.SQLServer.Replication objects from .net framework assemblies.
The synchronization starts normally (status is "Running"). The last message of selected session box shows (among other messages): "Beginning evaluating partial replication filters" then "Finished evaluating partial replication filters" and finally "Merge completed after processing xxx changes... etc." after a few seconds. Status changes to "Completed" and then... the merge process starts again!! "Beginning evaluating partial replication filters" etc. And this repeats about 15-20 times.
And so whole process takes about 15 minutes instead about 45 seconds to complete initial synchronization. The number of changes is "Merge completed after processing ..." never change since the first such message.
Is this some bug in web synchronization or some invalid configuration setting? Why does merge process repeat itself so many times??
Please help, thanks in advance.

I having a problem importing a text file into an existing table using the DTS import wizard. The problem I am having is, I am getting an error message stating: Integrity violation: attempt to insert null data or data which violates constraints. The column the error is referenced to is an identity field and I am not trying to insert any data into the field. I have the allow insert identity box checked in the transformation section. Does anyone know about how to solve this problem.
Thanks

I have a table with 5 columns .Length of the 2nd column is 4 characters.
I have to create a new database and copy the existing data.Alter the 2nd column to have 6 charactrers.
Append the values in 2nd column with 00.
I have only one row in the old database.
I am able to copy the rows.But after that when I try to update,it is giving primary key violation error.
What could be the reason?

System Spec: OS = Windows 2000, SQL Server 7 SP4.
I'm getting the following error when I run a stored procedure which truncates a table then inserts data into it. There are no complex joins, order, group by or union clauses in the insert statement:
Error: 0, Severity: 19, State: 0
SqlDumpExceptionHandler: Process 17 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
I've read that this is fixed in SQL 7 SP2 but we're on SP4?? I have re-installed SQL SP4.

I am running SQL 6.5 service pack 5a.
I keep getting a Attempt to insert duplicate key row in object... when I try to add a record. I know for a fact that the primary key is not being duplicated because I can look in the db and see that it is not there and if I continue to try to add it it will eventually succeed. Does anyone know what might be causing this?
Please email as well as post.
Thanks.

Hi,
I have got a very peculier kind of problem. My package is running on SQL 2000. There is a identity primary key in a table. Now when I submit the data from 2 different computer at the same time. Only one data is storing. The reason behind this is the primary key violation. as both the data are sending the request to the database at the same time.................n as the primary key is th identity column, it is storing one that value which is able to store the data at the forst hand.
Now plz help me out in this regard................. :confused:

I am maintaining a stored proc that does the following (pseudo code for simplicity)
INSERT INTO MyTable (CountColumn, ...) VALUES (1, ...)
-- 2627 = Primary key violation
IF (@@ERROR = 2627)
UPDATE MyTable SET CountColumn = CountColumn + 1
WHERE ...
Basically, try to create a new record with a PK and a count of 1. If a PK violation occurs, UPDATE the count of existing record.
Pretty simple logic. On some servers this works exactly as expected; the PK violation is caught and handled internally. On other servers, this error percolates out of the stored proc and causes the calling code to receive an error and fail. All servers are SQL Server 2000 SP3a Standard Edition. Any ideas why this happens?
Is there a better (and ideally as fast or faster) way to handle the INSERT/UPDATE issue? I can put the UPDATE first and INSERT if @@ROWCOUNT is 0, but that has the slight potential of a race condition where two processes try to INSERT the same PK at the same time.

Dear Friends,
I am a DBA and I am getting a lot of table locks due to unhandled errors in front-end developed by Power Builder, 5 years back. The backend is SQL Server 2000 Enterprise edition. Below I will explain the problem in detail.
The Big Problem.
{
Ø Users enter sales data into rm_salehdr (docid,..,..,..) table (LOCKED)
Ø The rm_salehdr table need a new docid
Ø The new docid will be generated by a function called as docnogen
Ø The docnogen function
o will select the last docid from ps_docno table
o add 1 to last value
o return docid to rm_salehdr
o update the last docid with the new value.
o ps_docno table will hold the lock till the insert transaction of rm_salehdr will saved. (LOCKED)
Ø If insert into rm_salehdr commit then the insert into ps_docno will be commit. (LOCK Released)
Ø If insert into rm_salehdr rolled back then insert into ps_docno will be rolled back.
Ø (LOCK Released)
}
The Bigger Problem
{
Ø At the same time if another spid select the last docno and completes it transaction before the first transaction then Primary key Violation will arise.
Ø While inserting into rm_salehdr if a user get a error due to primary key violation then user will popped up with a message box explaining the primary key violation error.
Ø If the user does not click the OK button then the transaction will not be ended and LOCK on the table will not released from rm_salehdr.
Ø The LOCK on ps_docno will also be continued.
}
The Biggest Problem
{
Ø My client doesn€™t want to modify the front-end, it is very expensive for them and deployment to remote site is also a problem for them.
Ø They want me to handle it from the backend.
}
Is it possible that to handle the error message and release the lock on rm_salehdr from backend.
Commit the data first in ps_docno so lock will be released
I want your valuable suggestions and advice.
Thanks in advance.
Regards,
Raj

Hi,
On a regular basis, it seems that the primary key of my table gets corrupted and I get the error message below. I can still read the data but no longer update or insert.
There is no reason why there should be such error. I fix it by creating a temporary table and copying the data accross, then renaming the
table, but I would rather prevent it. Any thought on this??

I need to find out which record I am violating by trying to execute this stored procedure

GO
when I execute it I get this error message

The statement has been terminated.
Stored Procedure: GamingCommissiondb.dbo.InsertCorovan2004
Return Code = -4
I am trying to insert 2004 terms into the corovan table from TERMINATION table. How do you find out what records match from each table (compare the tables reocords for dups). How would I do this in the query analyzer since thats mainly what I use. I get a better understanding of how to create proceudure in the query analyzer so I;d rather stick to it.
In short I need to find the Culprit record that is preventing me from insert the 2004 records

If not exists

ASSET_ID= @v_ASSET_ID AND
ASSET_TYPE = @v_ASSET_TYPE AND
Value = @v_Value AND

The exact error is

When I try to insert data into a table (let's just call it MyTable for this post), I suddenly get the following error.
Violation of PRIMARY KEY constraint 'PK_MyTable'. Cannot insert duplicate key in object 'MyTable'.
My table does have a primary key field named 'id', which is an auto-incrementing BIGINT. The last record I successfully inserted received 14 in the id field, so I'm assuming the database is trying to assign 15 to the next. Unfortunately, there is already a record with an id of 15; the next available id is 21.
Is there a way to avoid these primary key collisions?

I thought the whole point of 'check constraint' being unticked meant you could whack your data straight in no probs.
How can I insert a bunch of historical information where I want to control the PK, in this case DealID?
I have got 'keep identity' checked.
I check the db, the Id does NOT exist currently.

Hi,
I've a set of source tables on one server and a set of destination tables on another.
When I move data from one server to next, I get an error saying "Violation of Primary Key Constraint". This happens for only one table among the 6 tables that I have. I dont understand why it throws me this error. Though theres an error for this table, the data from source table moves into this destination table.
Am I missing something?

where [report number] not in (select [report number] from pedtable)
drop table pedtable
drop table truelowspeed
drop table lowspeed
drop table notlowspeed
_______________________________________________
Let me explain what I'm trying to do.
In the first temp table "lowspeed," I'm trying to lump all crashes where a vehicle was doing between 1 and 10 mph.
In "notlowspeed," I'm setting up a table of crashes in which at least one vehicle was going over 10 mph.
By the third gyration, I'm trying to generate "truelowspeed;" which I thought would contain only crashes in which all of the criterion in the first two queries were satisfied and all of the vehicles involved in the crashes were doing between 1 and 10 mph (NO vehicles exceeding the 1 to 10 mph parameter).
The "pedtable" maneuver is simply to pull out any of these crashes in which a pedestrian was involved.
What I'm getting is a lot of crashes in which I have dummy records, several crashes in which one of the vehicles was going over 10 mph, and types of vehicles involved in the crash that should have been excluded by the criterion I specified.
Thoroughly stumped. Would be most grateful for any kind insight/advice.
