Stored Procedure Based Custom Conflict Resolver Truncates Data
May 17, 2007
I created a stored procedure based custom conflict resolver in SQL 2005, I return the winning result set and also save that result set to a test table to compare the values. The values saved to the test table are correct but some of the values saved as the conflict winter are truncated.
Example a char(3) filed is updated at the subscriber as 111 and updated at the publisher as 222, in my custom conflict resolver if I use the value from the subscriber the conflict resolver updates the field as 11 , if I use the publisher value the conflict resolver updates the field as 22 . Now the same records is saved to the test table correctly as either 111 or 222 depending on the logic I used. So the result set has the correct values, its after the custom conflict resolver is called where the values is somehow truncated. Has anybody run into this before and what steps can I take to avoid this.
I am working on a COM-based custom conflict resolver (vb.net) for a merge replication problem that I am having. This is what I am trying to accomplish. 1. Have a Last_Upd_Dt column. 2. When there is a conflict between publisher and subscriber on a column, the winner is the most recent date in Last_Upd_Dt and want the value for that column from that source. 3. If there is no conflict on a column and the column was updated by either the publisher or subscriber, I want to keep the change made by the publisher or the subscriber. (i.e publisher made change in col #1, subscriber made change in col #2, no conflict, the resulting row will now have the col #1 value from publisher, col # 2 will have value from subscriber. Essentially merging the changes.)
Does anyone have any examples of a COM-based Conflict Resolver that implements ICustomResolver for SQL Server 2005? Can this be done using the Business Logic Handler (examples?) ?
I have created a custom conflict resolver for an article that is using Merge replication. I can register my custom resolver OK, I can change my merge article to use my new custom resolver, but when a conflict occures the replication monitor shows the following errors:
Error messages:
No signature was present in the subject. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2146762496) Get help: http://help/MSSQL_REPL-2146762496

At first I thought it was because my assembly wasn't signed, so I signed it. I still get the same error.
I have various debug statements in the assembly and I can see that Initialize and HandleChangeStates gets called ok, but no other overrides.
I'm trying to create a custom conflict resolver for SQL Server 2000 in C# but i can't seem to find any source code examples of a *.dll where i can actually see what needs to be done.
I need to write a custom conflict resolver for an application using merge replication. It's relatively simple logic - compare the two rows from the publisher and the subscriber and the winner is based on the value of one particular column.
Reading BOL gives me the input parameter list for the sp, and specifies that the output should be exactly the winning row. What is doesn't give is any example of how to do this, in particular how to access the two rows in conflict so that they can be compared.
I can do this by dynamically building SELECT statements, one connecting to the table locally on the publisher and another connecting to the subscriber using the form SERVER.DATABASE.OWNER.TABLE, but this requires me to explicitly have the subscriber as a linked server to do this. An example of my revolting code is appended to this post.
Is this what I have to do, or is there some table I can access on the publisher that has the conflicting rows in so I can compare them without going back to the subscriber?
Thanks for your help

---- code sample --
ALTER PROCEDURE [dbo].[prRep_ResolveInventoryConflicts]
CREATE TABLE #ConflictingRows ( [Machine] [sysname]NOT NULL, [LocationID] [int] NOT NULL, [PartGUID] [uniqueidentifier] NOT NULL, [Qty] [int] NOT NULL , [LastUpdatedDtm] [datetime] NOT NULL, [LastUpdatedUser] [varchar](50) NOT NULL , [rowguid] [uniqueidentifier] NOT NULL
)
-- Build the T-SQL To run against publisher and subscriber
SET @Publisher = @@Servername SET @qryPublisher = 'INSERT INTO #ConflictingRows SELECT '+@Publisher+' as Machine, * FROM '+@tableowner+'.'+@tablename+ 'WHERE rowguid = '+CAST(@rowguid as varchar(40)) +';'
SET @qrySubscriber = 'INSERT INTO #ConflictingRows SELECT '+@subscriber+ ' AS Machine, * FROM '+@subscriber+'.'+@subscriber_db+'.'+@tableowner+'.'+@tablename+ 'WHERE rowguid = ' + CAST(@rowguid as varchar(40)) +';'
-- execute the stored procedures
EXECUTE @qryPublisher; EXECUTE @qrySubscriber;
-- Compare the two rows and return the winning row, ie the one that was last updated by a human checking the inventory
SELECT @RecentCheck = MAX(LastUpdatedDtm) FROM #ConflictingRows
SELECT TOP 1 * FROM #ConflictingRows where LastUpdatedDtm=@RecentCheck;
When conflict occur, I want the user to be able to select witch row to keep and witch to delete.
I've look for system stored procedure, that could help me do the resolution but I've founded nothing.
So I've thought that I could do it by hand, with UPDATE/DELETE query Take the row in the %TABLE_NAME%_Conflict table and copy it into the real table, than delete the row.
I'm trying to setup the Interactive Conflict Resolver in my C# app via RMO. (using SQL Server 2005)
The only article I can find on MSDN or anywhere is involing T-SQL. Can someone please shed some light on this for me specificaly on the subscriber side.
Hi, I'm replicating a database between two instances of Sql 2000 using Merge Replication. I have no custom resolvers at present but I'm seeing something unexpected.
I see that MS has a conflict viewer that can be accessed by managment studio, however I would like to create one with some customized options. Is there a sample of code somewhere to start this? I could really find anything in BOL. Thanks in advance.
I have been evaluating merge replication, 'push' subscription on SQL Server 2014. If the default resolver is used (I refer to @article_resolver parameter of sp_addmergearticle), all seems to work as expected. However if I use "Microsoft SQL Server Subscriber Always Wins Conflict Resolver" (or any other MS standard resolver for that matter), if the Subscriber is on a different machine, the merge agent invariably gives the following error: "The process could not initialize <resolver_name>. Verify that the component is registered correctly."
This does not happen if the Subscriber is on the same machine as the Publisher and Distributor.
The problem seemed to exist in SQL Server 2008 according to some posts but it has been apparently fixed since then. I've tried the following:
- @partition_options = 0, as was suggested somewhere.
- Copied ssrpub.dll (the resolver dll) to the Subscriber machine (should not really matter as this is 'push' subscription?)
- Registered ssrpub.dll with regsvr32 on the Publisher/Distributor machine.
I've also run sp_enumcustomresolvers on the Publisher machine, and it happily showed all standard resolver, including the "Microsoft SQL Server Subscriber Always Wins Conflict Resolver".
Another thought is, I'm using SQL Server Express as the Subscriber (on the remote machine). Perhaps it does not support custom resolvers? (I'm using the full SQL Server in the 'local subscriber' variant, which does work OK as I mentioned before).
Note also that if I create a new publication via SSMS, the Resolver tab of the Article Properties dialog is empty, i.e. it does not list any resolver. The same tab contains the full list of resolvers though, if opened for an existing publication.
I have a custom conflict resolver - which fires on update conflicts (using row level tracking)
I have had a couple of occasions when the resolver has failed with the following error:
"The schema of the custom Dataset object implemented in the business logic handler does not match the schema of the source Dataset object. Verify that the custom Dataset object has been correctly defined"
In both cases I found that the row for which a conflict was being handled was not a conflict at all. One was a straightforward non conflicting update at the publisher and the other was a similar update at the subscriber.
I got round the problem by temporarily using a fix version of the conflict resolver dll that either set the custom Dataset to the publisher dataset or the subscriber dataset - depending on where the update had occurred.
When the first error (publisher update) occurred - the resolver code was basing the custom dataset on the publisher dataset - which was presumably empty - so I changed the code to base the custom dataset on the subscriber dataset. The second error therefore occurred when the custom dataset was based on the subscriber dataset - which again was presumably empty
Note that the tables involved in each occasion were different and neither table is filtered.
Is there a known bug in this area?
I am considering trying to change the resolver code to identify false conflicts in order to workround the problem - but this would be difficult to test as I can't reproduce the problem
I am new to working with custom data types. I am trying to use one as an input parameter for a stored procedure, but I'm not sure what the syntax is.
I the design table view, the data type shows up as this: DISPOSAL_AREA_NAME_TYPE:varchar(40)
What is the proper way to reference it in a stored procedure? Here is what I have, but it errors out: CREATE PROCEDURE webservices_BENEFICIAL_USES_DM_SELECT @DISPOSAL_AREA_NAME [DISPOSAL_AREA_NAME_TYPE:varchar(40)] = "" AS BEGIN
here is the context of our problem: - Publisher : version SQL Server 2005 SP2, table in SQL Server 2000 (80) compatibility level, publication in SQL Server 2000 compatibility level - Distributor : SQL Server 2005 SP2 - Subscriber : SQL Server 2000 SP4 + hotfixes (version 8.00.2187)
There is only one article in our publication (a simple table with a GUID and a nvarchar(50) columns), and we have left the default resolver.
1 - The first synchronization of the subscription is successfully completed, and it is the same for the different updates/inserts/deletes or conflicts.
2 - Then we change the Resolver of our article by our own COM-Based Custom Resolver (developped in C# 2.0). This resolver only change the default behaviour: the subscriber always win (this is for a test, in the future we will have a complex business logic). All the synchronizations works fine and do what we want in the conflicts.
3 - We rollback the resolver to the default one... and here is the problem!
The synchonizations stop to work correctly. For all of them we've got the same error: quote:Replprov.dll , 2007/09/25 14:26:07.591, 4000, 16890, S1, ERROR: ErrNo = 0x80045017, ErrSrc = <null>, ErrType = 8, ErrStr = The schema script ' declare @cmd nvarchar(1000) set @cmd='exec sys.sp_MSchangearticleresolver @article_resolver=@ar, @resolver_clsid=@rc, @artid=@ai, @resolver_info=@ri' exec dbo.sp_executesql @cmd, N'@ar> nvarchar(255),@rc nvarchar(40),@ai uniqueidentifie..." mailto:N?@ar">N'@armailto:N'@ar">N'@ar</A< A>> nvarchar(255),@rc nvarchar(40),@ai uniqueidentifie...
It is no more possible to synchronize this subscription... Any remark will be helpfull cause we did not find anything on the net concerning this error.
I'm trying to create a custom resolver for merge replication exactly like in the MS example.
It seems to work, but only ONE time. If I change, insert or delete a record in a table the second time, the subscriber monitor comes with the following errors:
Error messages:
Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199411)
The Merge Agent encountered an error when executing code in the 'UpdateHandler' method implemented in the business logic handler 'D:Program FilesMicrosoft SQL Server90COMMyResolver.dll'. Ensure that the overridden 'UpdateHandler' method has been properly implemented in the business logic handler. (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199411)
This last error is of course dependant on my action (update, delete, insert).
My code is -exactly- like the example (I just stripped out the log message).
Does anyone know why I am "trying to read or write protected memory" ?
The thing is that I'm trying to create an application that detects if a table changes. Is this the right way to do this anyway or are there better solutions?
I have created a custom resolver in VB .net (VS2005). The resolver works ( Both Publisher and Subscriber are SQL 2005 ), but I need to be able to debug the code within the resolver. How do I do this? I have tried a number of things without success.
Hello, I am hoping someone can help me in this. I am looking to write a stored procedure that will return the heirarchy of an organization. I will display how the heirarchy might look and then list the tables involved.
John Smith
- Jacob Jones - Lisa Thompson - Samuel Barber
- Paul Smith - John Jackson
Ok, so Jacob, Lisa, an Samuel report up to John Smith. Paul and John Jackson report up to Samuel Barber.
Here are the tables:
Users holds the user_id, first_name, last_name, and reports_to_user_id. User_Roles holds the user_id, role_type_id Role_Types holds the role_type_id, and the type (which could be Administrator, Standard, Guest) for example. In addition, Role_Types also has ranking which must be taken into consideration as well. 1 being the top rank and 9 being the lowest.
I'm having some difficulty getting the appropriate results for my scenerio. I have two different datasets that I'm using. One is consisting of two joined tables and the other consisting of one sp. The sp's parameters rely on two things- one is the companyNum (inputed when the user runs the report) and two is the ContactNumType. The ContactTypeNum comes from the dataset of tables. I need to have a table consisting of this format:
ContactNumType1 (From the Tables) File_Name1 (From the sp) File_Name4 (From the sp) File_Name3 (From the sp)
ContactNumType2 (From the Tables) File_Name2 (From the sp) File_Name7(From the sp)
ContactNumType3 (From the Tables) File_Name5 (From the sp)
ContactNumType4 (From the Tables) File_Name6 (From the sp)
File_Name10 (From the sp) File_Name8(From the sp) File_Name9 (From the sp)
So essentially what is going on is that every returned File_Name is grouped based upon the type of ContactNumType. My table returns the appropriate ContactNumTypes and the appropriate number of File_Names but returns only the first File_Name for each row. The File_Names should only grouped by the ContactTypeNums and each be unique. Is there any way to do that?
------------------------------------------------------------------------------------------- Edited: I still am trying to work this out. I've tried a few run-arounds but none have worked. Adding custom code apparently is too risky at this point because of the security precautions that I've been instructed to take. Any help would be greatly appreciated as this project has been going on for days now....

I am writing a number of data migration scripts, like the (simplified version) below
Code: INSERT INTO newDatabase.dbo.DaDestinationTable(col1, col2, col3) SELECT col1, col27, col13 FROM OldDatabase.dbo.DaSourceTable
There are no validation rules defined in the database (don't ask why), only in the program code. Because of the absence of validations in the database, the data migration scripts could violate business rules (NOT NULL, FK violations, domain values in a column, ...).
A solution could be that both the program and the data migration call the same stored procedure to insert records in the destination table, so the validation rules must only be defined in one place (the stored procedure).
I have never used stored procedures in a "set-based" situation. Is this even possible? The only solution I see is to call those sp's in a loop (WHILE or CURSOR). Something like
Code: SET @my_id = -1 SELECT @my_id = MIN(id) FROM OldDatabase.dbo.DaSourceTable WHERE id > @my_id WHILE @my_id IS NOT NULL
[Code] ....
For each record, the table OldDatabase.dbo.DaSourceTable is hit twice, once to get the next id (@my_id), once to get the column values. I could combine both with one SELECT script by using ROW_NUMBER(), but I doubt that that will perform faster.
I only work set-based, I have barely ever used a WHILE loop, let alone a CURSOR. What the consequences will be on performance. There are millions of records that have to be migrated.
I was thinking of CROSS APPLY, but you can't use that in combination with a SP.
I have created an SSIS package where I have added an Execute SQL Task to run an existing stored procedure in my SQL database.
General Tab:
Result Set: None Connection Type: OLE DB SourceType: Direct Input IsQueryStoredProcedure: False (this is greyed out and cannot be changed) Bypass Prepare: True SQL Statement: EXEC FL_CUSTOM_sp_ml_location_load ?, ?;
Parameter Mapping:
Variable Name Direction Data Type Prmtr Name Prmtr Size User: system_cd Input NVARCHAR 0 10 User: location_type_cd Input NVARCHAR 1 10
Variables:
location_type_cd - Data type - string; Value - Store (this is static) system_cd - Data type - string - ?????? The system code changes based on the system field for each record in the load table
STORED PROCEDURE: The stored procedure takes data from a load table and inserts it into another table:
Stored procedure variables: ALTER PROCEDURE [dbo].[sp_ml_location_load] (@system_cd nvarchar(10), @location_type_cd nvarchar(10)) AS BEGIN .....................
This is an example of what I want to accomplish: I need to be able to group all system 3 records, then pass 3 as the parameter for system_cd, run the stored procedure for those records, then group all system 18 records, then pass 18 as the parameter for system_cd, run the stored procedure for those records and keep doing this for each different system in the table until all records are processed.
I am not sure how or if it can be done to pass the system parameter to the stored procedure based on the system # in the sys field of the data.
For my ASP.net Application on a hosted MSSQL server, i have had to re-ceate using the scripts generated from my local machine using sql tools with SSMSE. This worked beautifully and all appears to work. My ASP.net application users can create their accounts and login normally. Unfortunately, my create user wizard does not automatically generate roles for the clients. So, i am using a routine that includes the following Protected Sub CreateWizard1_OnUserCrated(ByVal sender As Object, ByVal e As System.EventArgs) Handles CreateUserWizard1.CreatedUser Dim userInfo As MembershipUser = Membership.GetUser(CreateUserWizard1.UserName) userInfo.IsApproved = False Membership.UpdateUser(userInfo) Roles.AddUserToRole(CreateUserWizard1.UserName, "Friends") End Sub which does not work because it is looking for a AddUserToRole stored procedure. This is confusing because it this SP IS on my local version and works fine. So i attemtped to create a new SP called AddUserToRole on the server but get an error message Msg 468, Level 16, State 9, Procedure aspnet_UsersInRoles_AddUsersToRoles, Line 49 Cannot resolve the collation conflict between "Latin1_General_CI_AS" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation. (actually it occurs 5 times in the routine). Further research from the various SQL forums and even MSDN points the problem as one of Collation versions - and suggest the answer is to re-install. I was wondering if any might know of a way of changing the collation version . Loking at db properties on my server db has the collation version set to SQL_Latin1_General_CP1_CI_AS. I do not understand enough about sql to know if changing the version the Stored Procedure wants to use as its default ( which appears to be Latin1_General_CI_AS). ANY IDEAS????? As i have already deleted and re-installed my mssql db, i would rather find an alternative / better solution. many thanks in anticipation. steve
I am doing a work were i have to syncronize data between a Publiser (PC, SQL SERVER 2005), and a subscriber (Pocket PC, SQL CE MOBILE). I studied lots of articles and i managed to put the syncronization to work, the problem is in conflict resolution!
The subscriber can΄t insert or delet, only update!!
For exmple: I have a table that contais the quantity of a product X, for example 100 units, this goes to Pocket, but later arrive move 100 units that are increased in the PC, so we get 200 in the PC, (but 100 in Pocket), no problem if i syncronize now (Pocket will have 200 too), but if remove in Pocket for example 50 units, i've changed the same column in both Publisher and Subscriber database, if i syncronize now, i'll have a conflict, the final result should be 150 of product X in both databases (100 + 100 - 50), but the Publisher wins the conflict and the final result is 200!
I never worked with stored procedures and in microsoft theres and article called How to: Implement a Stored Procedure-Based Custom Conflict Resolver for a Merge Article (Replication Transact-SQL Programming), but they dont explain it very well and i dont know how to do my own stored procedure and implement it to the merge article.
in my own stored procedure i'll have to do some calculations to get the result i want, maybe using some table for the additions and subtractions. (Does the com based Addition resolver do this for me???)
Maybe you have experienced some problem like this, and could help me!
How should i do the stored procedure?
Oh, i tried to use de addiction resolver and the average resolver of com based but nothing happed, dont know why, i read some stuff and i think the addition could solve my problem, but it doesn΄t work, i read above what you said and installed service pack 1 for sql 2005, but i instaled and nothing happened! When i change to the resolver that the subscriver wins, it works, why addition dont work?
I have gone through BOL and various online resources including this one and I can't find any examples on how to use custom conflict resolvers to generate a result row which is a combination of the rows to be merged.
BOL says it can be done, but suitable examples are missing. I have found various posts requesting examples from up to a year ago, but can see no replies with relevant information
In particular I would like to see examples of

I need creating a store procedure which generates custom IDs for each asset. I am programming for Fixed Assets in VB6 with SQL Server 2005. For example, when a new Asset is added ,I need to auto generate the ID based on existing IDs. New ID should not exist in tblAssets table.
Table Name : tblAssets Fields : AssetID > Int,Primary Key,this is internal ID (identity seed) AssetExtID >nvarchar(50),this is external ID, need to generate/user entered.
Below is the example of data in tblAssets :
AssetID AssetExtID ProjectID ItemName Qty UOM UnitCost ..... 1 PROSP-00001 PROSPERITY SPLIT-AC 2 NOS $200 2 PROSP-00002 PROSPERITY LAPTOP 1 NOS $500 3 UNIII-00001 UNION III LAPTOP 5 NOS $400 4 UNIII-00002 UNION III RECEIVER 2 NOS $312
The AssetExtID depends on the ProjectID which is in tblProjects.
I will take care of the first 5 characters to generate. But the number part I need to generate by checking existing data. The AssetExtID should not be duplicate. Its unique for each asset.
How come no matter what I do SQL server always truncates my dates when they are saved to the database? I save a complete date like 1/1/1900 6:13:42 and no matter what I do it always truncates the seconds off of all my dates, so I always get 1/1/1900 6:13:00. It makes no since because when I save the record the seconds are there, but when I pull it back up they are always gone.
The sql database has an ntext (16) field which contains "information" and is used as a free form turnover log. When I bring this data into an ASP page the "information" gets truncated.
I have tried getchunk, however all formatting on the field is lost. I have tried putting the field at the end of my query - no change. I have tried querying the data as a separate sqlrs connection - no change. I have tried using substring to break it down, the first substring works, however I get errors on the second (Expression result length exceeds the maximum. 8000 max, 12000 found).
I also tried to use substring in sql query anaylzer - and only get the first ~4180 characters.
Is there a way to split this field into multiple nvarchar fields in my temporary table in sql and then concatenate back together in asp report???

I'm importing from a SQL table that has data fields typed as numeric(18,2) and the OLEDB data source component converts the data to integers (as viewed in the data viewer). I've preceeded the column names with (DT_NUMERIC,18,2) with no results. When the data gets saved to a table with the field typed as money, it appends .00. The truncation of pennies (decimal) results in the diminution of the daily results as much as $1,000. How do I pass the pennies through the OLEDB data source component? Is this truncation by default,or is there something I'm missing in the configuration? thanks.
