Merge Replication Columns Limit??
Dec 4, 2006
Hi,
I am experiencing a wired problem withe merge replication and SQL 2000 SP4.
We had replication working for 4 years without a problem, one of the table that we replicate has been growing in columns, now it has 55 columns.
I have noticed a problem, when I update the last column on the table and waits for the change to be updated on the subscriber the change is not there. But if I replicate the first 40 columns it works.
Changes made:
1) Upgraded to SP4
2) Added some extra fields using sp_addreplcolumn
Is this a known bug? Any ideas?
Regards

I think I want to use merge replication but filter out one column but when I'm setting up the publication I only see row filtering available?
Is this just not possible?
Thanks for any help

Dear all participants,
I manage complete online system for two locations, connected via dialup lease line. I have to used merge replication for the same data should be at both locations. It is working fine, I don’t like disturbe it but current requirement is addition of two column in one table which one as also use in merge replication.
How I can add aforesaid columns in table x, column name c1 numeric , c2 character?
What is impact on replication?
Let me know step by step.
Thanks in advance.
Thanks R.Mall

I was reading this:
"Adding an identity column to a published table is not supported, because it can result in non-convergence when the column is replicated to the Subscriber. The values in the identity column at the Publisher depend on the order in which the rows for the affected table are physically stored. The rows might be stored differently at the Subscriber; therefore the value for the identity column can be different for the same rows."
I don't understand...
If I create a table with an identity column and publish it. Can the values on the subscriber be different when the data is replicated?
Suppose I have a this table:
1 Name1
2 Name2
3 Name3
Column 1 is identity field and column 2 the name of employees.
If I publish this table , the data can be inserted on the subscriber .pe, with 2 name1 and 1 name3 and 1 name2?
What about if the identify fields is a primary key?

Hi,
I read the BOL on how the publisher will had out identity ranges to subscribers, but it was not clear if this was also the case for anonymous subscribers. Will merge replication with identity columns work with anonymous subscribers that sync via HTTPS?
Thanks,

I am trying to add two columns together and find all the entries that equal zero I have:
select table1.nbr, table2.itemvalue as CC
from table1, table2
where table1.nbr=table2.nbr and exists (select (OpnAc1+OpnAc2) as Open from table2
I want to take the sum of OpnAc1 and OpnAc2 and find all that equal 0, (meaning no open 1 or open 2)

HI all !
I am having a bit of a problem trying to limit a number of columns in a matrix appearing on a page.
At the moment, I have a dataset that lists the month and the mail packages that were sent during the month
The matrix works great HOWEVER, if there were more than 8 months in the matrix columns, it does not break and would make the page look like a huge landscape page.
I am trying to limit the number of columns appearing (this is the months column) on the matrix so that the pages stay in a potrait position. IE: every 8 columns appear on one page. Is there an option or an expression I could use in the Matrix ?
Thanks!

I was asked if there was a limit on the amount of clock time that the Replication agents may be down without snapshotting the subscribers. I think that the only factor is if the MSDB database contains the necessary data to feed a restarted Replication Agent.
Any comments?

Hi all,
I know that adding a column using ALTER TABLE to add a column automatically allows SQLSERVER 2005 to replicate the schema changes to the subscribers, however, I would like to add a new column to an existing article that is being used for merge replication, however, I don't want this column to be replicated. Re-initialising the subscriptions is not a option. Help would be appreciated.
I am using SQLSERVER 2005 (SP1).

I am being told that the colid in syscolumns may not exceed 255 if the table is replicated. Is that true? Where in BOL or elsewhere can I read-up on this? This is a shocking development!!!

Hi,
I€™m trying to create a VERY wide table, with 1,000 columns of type varchar(MAX), nullable.
The CREATE TABLE statement (both in SQL 2005 & 2008), gives the following warning:
Warning: The table "WIDE_TABLE" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit.
When I insert data into the table, filling all columns with small, 10-byte string values, I get the following error:
Msg 50000, Level 16, State 1, Procedure sp_pivot, Line 118
Cannot create a row of size 15034 which is greater than the allowable maximum of 8060.
I€™d like to verify this observation: each row is created with 2000 bytes of offset data (2 byte * 1000 columns), 125 bytes for null bitmap (1000 columns / 8 bits) and some more €œwasted€? row information. This leaves less than 6K for the data itself. But since not all columns can fit within the page, forwarding pointers in the row need to be created, 24 byte per column, which very quickly add up to more than 8K, thus the error. So the 8K limit is met for much less columns than the max 1024 column restriction.
Furthermore, in SQL 2008, SPARSE columns will not solve the problem (maybe save some €œmetadata€? space in case the columns are null, but if not, I€™m with the same problem again, or even worse, since now each value takes more storage space. The max 30,000 columns in 2008 is only for cases where the column values are really sparse€¦
Is this the right observation? if so, is there a workaround besides splitting to multiple tables?
Thanks,
Aviv.

I have created the matrix report which has dynamic column, it grow columns(18) based on the 'MCU' field in PRD.MI table. I have added the 'MCU'(A,B,C,D,E,F,G,H,...Q) on 'Columns' in matrix table, to create matrix report and I have added 'mcst' on 'Data' in matrix table and I have added the 'msp2' on 'Rows' in matrix table. I have created new column after row and I added USP2DS.Final output is as given below.I need the split the matrix column per page.
I have added the 'MCU' on "Column group and 'msp2' on Row group.

I am working on bringing our disaster recovery site to be a live site. Currently we replicate to one of out servers (server B) with merge replication (from server A). Server A also does one way transactional replication form some table to several other servers including servers at the DR site.
This setup is not going to be fast enough for what we need so I am wondering if a table is receiving merge replication will the merge updates also replicate down the transaction path??
Example...
Server B update a row and merges to Server A. With this update them replicate (via transactional) to Server C??
thanks...

Hi,
I am planning to use transacational replication (instead of merge replication) on my SQL server 2000. My application is already live and is being used by real users.
How can I ensure that replicated data on different server would have exact same values of identity columns and date columns (where every I set default date to getdate())?
It is very important for me to have a mirror image of data (without using clustering servers).
Any help would be appreciated.
Thanks,
-Niraj

I want to combine a column with Id and other with Name.
For eg: If Id is 01 and Name is 'Tom', the output should be 01-Tom.
I am not able to execute it using || or CONCAT since Id has the data type int and Name is a string.
Do you have a solution?

Hi!
I'm using IS with SQL Server 2005.
I need to know how to merge two columns (or more) into a single on as output.
For example:
#ID#Value1#Value2#
would be the input table. Now I want to map the column Value1 as 'Value' - as well as the column 'Value2' so there is only one output - and two rows generated by one row of the originate table.
I tried to map those columns to the same name, but IS refused that. My aim is to transform data from an old table to a new, relational one where all those values have to fit into relational tables (n:m relations).
How do I do that?
Thank you in advance!

Hello everybody!
I´m trying to put together two columns of integer into one. They are coming from the same source table, so the "merge"-Task doesn´t work. This is what they look like:
column1: <123>
column2: <0123456>
The result should be:
merged_column: <1230123456>
Is there a task for that kind of operation or do I have to write a script? I would like do do that within the data flow.
thanks in advance!

Hi *,
I have a table with 2 columns A1 and Firm. A1 holds "dirty data" and there are no NULL values. Firm holds "clean data" for some of the rows in A1 but not for all. So there are quite a few NULL values in this column. I want to replace the value in A1 if there is any data in Firm (value <> NULL).
Rigth now, I solve this issue with a simple VB.NET script:
Public Class ScriptMain Inherits UserComponent Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer) ' If Row.Firm_IsNull Then Row.Standard = Row.A1 Else Row.Standard = Row.Firm End If ' End SubEnd Class
Any ideas how to solve this issue without custome code?
Thanks!

I have just installed replication on our production server to Merge Replicate with a Laptop server that will travel from time to time. I have now noticed that we cannot add or change any fields or attributes on the tables which are being replicated (which are all tables in the DB). This is a problem because we are changing and adding columns all of the time. Is there a way around this issue like shutting down the replication service or something? I have been unsuccessful in finding a way around this other than removing replication while we make changes.
Thank you in advance for any help!

Hi all,
I have a merge replication going between 4 servers. The problem is when ever I do some BCP transfer to one of the tables in one of the servers. It puts the data in that table. But that Data does not get replicated to any other server like it should.
Please Advice on what to do. Is there any option I am forgetting to set or something.
Thank you for all your time in advance.

Hi All,
I have posted this earlier and I am re-posting it simplifying what I had said.
The scenario is:
I have two sql server database instances with the same database schema and all. However, both of them have different data. I have not set them for replication at all. Now, I want to do merge replication between them such that the data between them could be syncronized.
When I do pull merge subscription I have two choices -
1.Bringing schema and data to subscriber from publisher
2.Not bringing the schema and data from publisher to subscriber.
Obviously, I chose the second choice. But upon syncronizing I dont see any data from publisher coming to subscriber and vice-versa. If I add new data to publisher and do syncronization, I can see ONLY the new data created after the replication setup in subscriber. If I add new data to subscriber and do syncronization then the new data is removed from subscriber and not propagated to publisher.
Is there any way I can make this work??
