Using Merge Replication, Parameterized Filters

Oct 6, 2006

Dear ppl,

I am using Merge Replication between SQL Server 2005 (Publisher) and Pocket PC (SQL Mobile 2005-Subscriber). I have a Windows Mobile appliction on the Pocket PC that replicates data from the server.

I am using SqlCeReplication class on the Pocket PC application to synchronise the data. By default, when i call the Syncrhonise() method, it pulls all the data from the server. What I want is to pass a parameter from the Pocket PC and filter the data based on that paramter. E.g. from the Employee table, I want only those Employee that belongs to a CompanyID that I pass as a parameter.

Is there a way to do this, so that i can pass parameters from my PDA application (Windows Mobile), and make the Filters specified in the Publication to use that parameter to filter out the rows.

Regards
Nabeel Farid

Merge Replication And Dynamic Filters

Jan 5, 2005

Hi,

I would like to setup a merge replication from a main database (publisher), to around 100 client databases (subscribers), that contain only subset information for each distinct client: each client has then its own database to view and modify its own data (Filtered on rows and columns). The client databases will initially be hosted on the same SQL server Instance.

I don't want to setup manually 100 publications with static filters, and more may come in the future: a pain to setup and maintain because I have to configure the tables, the columns and the row filters (and joins) each time.

I would like then to setup one publication with a dynamic filter, to filter in a way or another on a specific client. Creating subscribers becomes then a piece of cake. The dynamic filter would apply based on a property specific to the client, but... HOW?

Filtering on HOST_NAME() will not work because several subscribers are on the same server.

Filtering on SUSER_SNAME() will not work because merge agent will always use the same user name for connecting to the publisher (using push subcription, all merge agents are on the same server), and I have not find out how it can be configured by merge agent: even if the merge agent jobs have different owner, it is always the SQL Server Agent login that is used to connect to the publisher (I am using windows authentication).

I was thinking about using DB_NAME(), and have specific db name for each client DB, but DB_NAME() provides the name of the publisher DB, not the subscriber DB. etc ...

What could I use in this case to dynamically filter on client data without having to fall into heavy replication administration and setup.

Thanks for your help,

Best regards

Parameterized Filters On Publication???

Oct 20, 2006

Does anyone know if you can use any other parameters in the row filters for merge replication besides the functions SUSER_NAME() and HOST_NAME()?

I would like to create a publication for a couple thousand mobile databases to replicate with one SQL Database but filter what data they get based on some parameters. Do I have to hard code WHERE statements into static filters and create a publication for every user (seems a little ridiculous)?

Is there a proper way to do this using the SUSER_NAME and give each user a different connection name that will filter data properly?

Thanks,

Patrick Kafka

Disappearing Parameterised Filters And Filter Joins In Publication Properties Page Of Replication Monitor

Jan 22, 2007

Hi,

We have an issue with our replication configuration when viewed through replication monitor. Parameterised Filters and joined filters don't appear in the gui. However, when we script the publication all the filters are present.

This issue only seems to occur when we have a remote distributor.

I should also point out that we have a merge push topology that uses a custom RMO synchronisation component on a separate server to either the publisher or the distributor. Also all the databases in the topology are called the same name. This has caused us other issues relating to this topology in particular so I raise it here as well although I don't expect it to be the case in this instance.

Any help would be greatly appreciated in clarifying this matter.

How Do We Add A New Column To A Merge Replication Article, But Specify It As Not For Replication?

Aug 30, 2007

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).

Merge Replication Set Off Transactional Replication

Oct 9, 2007

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...
