Merge Replication: Does It Support UDTs && Defaults
Feb 27, 2003
Hi Everyone,
Can anyone help me with this little problem that im stuck with.
As part of the initial snapshot using merge replication, i am creating the initial schema on the subscriber database however it seems as though it does not like UDDTs or defaults and hence does not create them on the subscribers.
Its looking likely that I may have to create a script which executes on the subscriber which creates the initial schema then use merge replication to transfer data.
Does Merge Replication support UDTs/Defaults? If so how does it work?
Ive search many places though have come up with nothing.
Please help. = (

Been fiddling with SQL 2008 Nov CTP but now looking to deploy a 3.5 .sdf project using Merge replication. The 3.1 install sets up a web endpoint with sqlcesa30.dll and I have been running subscriptions just fine with that. But now I want to be able to create and manage my 3.5 publicatoin/subscriptions under SQL 2005 management console. I don't see how to create 3.5 sql ce databases there or to use 'configure web synchronization' to get a 3.5 web endpoint for syncing.
Am I missing something simple like registering the SQL CE 3.5 dlls to work with SQL management studio?
I want to install to this a production server with the smallest possible footprint and I do NOT want to inject SQL 2008 Nov CTP bits into that production server at all! So, how to deploy SQL CE 3.5 to production and set up 3.5 merge replication under SQL 2005?

I am developping a pocket pc windows application, using VS 2005. The SQL Ce that VS 2K5 uses is the mobile SQL CE 2005 (3.0). I uses SQL Server 2000 as the publisher. Is it possible to replicate SQL Ce 3.0 with SQL Server 2000?

I have done a couple of little projects in VB express and was pleased with the results. Now I have something bigger in mind and need to know if VB express version of SQL will support merge replication. If not will the full version support it?
Thanks

I'm importing a multi tab spreadsheet using Import wizard, which I understand to use the same internals as SSIS. The total number of columns in the spread sheet will be over 500. The import wizard defaults everything to varchar 255. I understand there is an XML file I can manipulate to change this and they are located
C:Program FilesMicrosoft SQL Server100DTSMappingFiles
Assuming one of these will control Excel defaults, which one is it? None of the names lend themselves to the Excel as a source. SqlClientToMSSql10?

In my main database I have declared a number of User Defined types for consistency across tables. However, as one might expect, I cannot then use the UDT in stored procs as temporary table datatypes since the UDT is not present in Tempdb. If I have to declare my #temp table columns as the native types, I lose the advantage. What is the preferred way of tackling this - could I create the UDT in model? or run scripts at server startup to create them in tempdb?

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 working on establishing a merge replication process between SQL Server 2005 and SQL Mobile 2005. I started with a new SQL Server 2005 instance and went through the Sample for SQL Mobile merge replication. So far so good.
Today, I tried to drop all support for replication on my current SQL 2005 test instance, so that I can start from a fresh instance and do another. I used Management Studio to drop all publisher and distribution settings and had several errors occur, where some roles were not allowed to be dropped because they had membership in them.
I dropped all the users that I added to the SQL logins and tried again.
Now I am trying to run the following script:
use AdventureWorks
exec sp_replicationdboption @dbname = N'AdventureWorks', @optname = N'merge publish', @value = N'false', @ignore_distributor = 'true'
-- Dropping the distribution publishers
exec sp_dropdistpublisher @publisher = N'XP-MIKED-LAPTOP'
GO
-- Dropping the distribution databases
use master
exec sp_dropdistributiondb @database = N'distribution'
GO
/****** Uninstalling the server XP-MIKED-LAPTOP as a Distributor. Script Date: 1/14/2006 2:16:29 PM ******/
use master
exec sp_dropdistributor @no_checks = 1, @ignore_distributor = 1
GO
The error I am getting from the first batch (sp_replicationdboption) is this:
Msg 208, Level 16, State 1, Procedure sp_MSmergepublishdb, Line 103
Invalid object name 'dbo.sysmergesubscriptions'.
To me it looks like all the publication objects have been already removed from AdventureWorks, but in sysdatabases, the category column still says 4 (merge publication). Since I can't just do this anymore:
UPDATE MASTER.DBO.SYSDATABASES
set category = 0
where dbid=8
I just don't know what I can do at this point. I can't even create a new publication in AdventureWorks because it thinks there is a sysmergepublications table in there and fails when there isn't.

Hi,
I try to setup a transactional push replication from MS SQL Server 2005 to Sybase ASE 12.5.3. ASE is known to MS SQL Server as a linked server using OleDB.
As table schema and data are valid at subscriber site I don't need a initial snapshot for the replication.
So I do some tests with sync_type (sp_addsubscription). First I tried 'none'. That works fine.
But the documentation says that it is depricated an I should use 'replication support only'.
But with this syn_type replication stops because is sends the following commands to the subscriber:
--
-- Transactional replication custom procedures for publication 'kunktable_pub' from database 'kunktest2':
--
----
---- Replication custom procedures will not be scripted for article 'kunktable' because the auto-generate custom procedures schema option is not enabled.
----
IF (@@microsoftversion >= 0x09000000) BEGIN EXEC sys.sp_MSrepl_setNFR @schema = N'dbo', @object_name = N'kunktable' END
Of cause Sybase ASE throws an error 137 'Must declare variable '@@microsoftversion' because it has no system variable @@microsoftversion. Furthermore a procedure sys.sp_MSrepl_setNFR is not known at ASE site.
So it seems, that sync_type ''replication support only' only works for MS subscriber but not for ODBC or OLEDB based subscriber like SYBASE.
Question:
Do I miss something ?
Is this a bug ?
Which sync_type should I use ?
Regards
Wolfgang

What's the current opinion on UDTs? Are they valuable? Do the benefits outweigh the costs? Are they an absolute no-no? Has there been anything authorative or groundbreaking on the topic since Alex P's blog back in October 2005?

Hi,
I'm new to SQL CLR programming and have recently implemented a few simple test UDTs. Typically I provide a property called Value and, if applicable, a method to display that value in a different format. For example, I havea UDT representing Australian states: the Value property returns the acronym (e.g. VIC) and the ProperName() method returns the full name (e.g. Victoria).
However, when I do a regular query, say SELECT * FROM Customers, the values in the column in which I am using the UDT are displayed as hex (I believe), for example '0x008064'.
Is this behaviour the result of a faulty implementation on my part or is it just the way SQL Server displays a non-native data type?
Here's the essential implementation code:
[Serializable]
[SqlUserDefinedType(Format.UserDefined, IsByteOrdered = true, MaxByteSize = 58, IsFixedLength = false)]
public struct udt_au_stateId : INullable, IBinarySerialize
{
private bool _isNull;
private AU_StateId _state;
private enum AU_StateId { ACT, NSW, NT, QLD, SA, TAS, VIC, WA }
public void Read(BinaryReader r)
{
SetStateId(r.ReadString());
}
public void Write(BinaryWriter w)
{
w.Write(_state.ToString());
}
public SqlString Value
{
get { return _state.ToString(); }
set
{
if (!SetStateId(value.ToString()))
throw new ArgumentException("'" + value.ToString() + "'" + " is not a valid Australian state or territory.");
}
}
public SqlString ProperName()
{
return GetProperName();
}
public override string ToString()
{
if (_isNull)
return "<NULL>";
else
return _state.ToString();
}
public bool IsNull
{
get { return _isNull; }
}
public static udt_au_stateId Null
{
get
{
udt_au_stateId u = new udt_au_stateId();
u._isNull = true;
return u;
}
}
public static udt_au_stateId Parse(SqlString s)
{
if (s.IsNull)
return Null;
else
{
udt_au_stateId u = new udt_au_stateId();
u.Value = s;
return u;
}
}
/* some implementation details omitted */
Best regards,
Ieyasu

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...

After I watch a video for how to create MS SQL Replication, I configure distribution and create the publication. The problem comes from subscription. If I create a "PUSH" subscription, it works fine. However, when I create a "PULL" subscription, I got the following error. Where I should look for solution for this error.

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??

Hi,
I have just set up Merge replication, I have two servers, server A and server B, the merge replication worked successfully but I don't quite sure which databases should or should not replicated? If not, what other methods should I use?
I would really appreciated any comments or advice out there!

Hi everyone
SQL Server BOL says merge replication can be done in only one direction. But my understanding is Merge replication happens in both ways between publisher and subscriber.
How can i allow data movement from only wince sql ce subscribers and not from publisher running sql 2000 and win 2k.
Please reply immediately bcoz i require a solution which has to be implemented very soon.
Thanks in advance

I am in a process of learning Replication in MSDE, especially Merge Replication
Server runs on MS-XP Professional
--------------------------------------
I have a sample Access project 'ReplTest' which has only table with only 2 columns.
DatabaseName:ReplTestDB
Table Name :TestTable
MSDE Instance Name:SVRMYINSTANCE
Now I would like to know how I can configure this database for merge replication
using SQL-DMO
Laptop runs on MS-XP Professional
--------------------------------------
I have another access project which is running on computer 2 and connected to the
ReplicaTest database.
MSDE Instance Name:LPTMYINSTANCE
My task is, when I am disconnected from server I would like to have a local copy of
the database to work with and then, when reconnected, need synchronization with the
server database and continue working from server database.
How to write this replication process from scratch using SQL-DMO objects in both Server computer
and Laptop computer.
I dont have enterprise manager in both computers since they use only MSDE
Can anyone help me?
Thanks in advance

Hi,
I have a problem when doing merge replication. I need to have a identity column on both the publisher and subscriber, eg id. When the publisher is down, my app will now reference to the subscriber and insert into the subscriber. However when the publisher is up, the app will reference to publisher and start to insert into the publisher. This will cause conflict in the id. Also, i need the id to be in running order, therefore i cant use range for publisher and subscriber. Anyone have idea how to solve this problem?
