Merge Republish Schema Changes
May 4, 2007
Hello,
I'm working on a replication topology that is completely merge. We have a single consolidated instance (SQL 2005 SP1 Standard) that holds all data and is a continuous push merge publication filtered by region to regional instances (SQL 2005 SP1 Standard). Then we have individual user instances (SQL Express SP1) that pulls from the republished regional instances which is filtered by user. Both publications have Replicate Schema Changes set to true.
I'm testing out changes to tables and sps on a test system I've been using this process:
1-Run Snapshot on the Consolidated instance
2-Verify all published articles have a status of 2 in sysmergearticles
3-Run Regional Snapshot
4-Verify all published articles have a status of 2 in sysmergearticles
5-Run alter table scripts
6-Once all three levels have the table changes, run the alter sp scripts
I've gotten to step 5 and and the changes get replicated to the regional instance just fine however only the existing column changes get replicated to the SQLExpress instance, not the new columns. Looking at the articles in the regional publication it shows the new columns, but they are not selected. I know I can manually select them (or probably write a script that adds them to the publication although sp_repladdcolumn has been depreciated), but isn't there a way to make this a completely automated process since it's just a republished database? Also is the process I'm using the correct one?
Thank you,
Aaron Lowe

I have a DTS package that updates information in a database for one of our clients. This information then needs to be republished to the websites which is done by going to a URL
Example: http://webrepub.DomainName.com/apps/publish.cfm?temp=1&ID=1101.
Is there a way from within the DTS package to execute/call the URL that performs the republishing of the websites with out opening a browser on the server.
TIA

Hi there,
I wonder if I can ask for some advise? I wish to use SQL 2005 and merge replication but I have a few concerns over the schema changes that I am allowed to do on the publisher.
Ideally I want sql replication to push all my schema changes from the publisher to the subscribers but I don't know if it can. or even if it is recommended.
I see the BOL suggesting that schema repl. was mainly intended for ALTER type of statemenets, but can I use it for CREATE and DROP type DDL too?
For example, if I add a new table at the publisher I presume I have to add a new article too for this table. Then how can I create a new snapshot? Is this even the right way of doing it? Similarly if I want to DROP a table at the publisher I'm guessing I have to also delete any existing articles too, then recreate the snapshot.
Are there better / safer ways of doing schema changes? Perhaps I'm best disabling publishing and asking each remote site / db to update their schema manually and then re-enabling the publisher?
Any help would be much appreciated.
Regards.

Hi all.
I 'm trying to set up merge replication between two servers that have the same schema databases. The two database have the majority of there data the same but as well as data inserted at a later time independently on the two servers. (The two servers were connected in a merge replication scheme that failed at some later time and replication was paused, but users continout to insert data indepentedly at the two servers.)
I need to get them up and running.
I cleaned replication at both servers, I recreated the publication at the puplisher distributor and all is fine.
When I create a push subscription to the subscriper I get the error invalid column name 'rowguidcol' .
I so far managed to have merge replication running on two identical databases (schema and data).
Just some thoughts. After some reading I found that it might be related to identities and identity range or indexes. I set the identity seed and increment at 2, 2 at publisher and at 1,2 at subscriper. (On the same tables at puplisher and subscriber.) Is that ok? is that the way to do it?
Digging a bit more Using the SQL Profiler I can locate the error to happen when sp_MSaddmergetriggers executes.
Thanks allot for any help

Hello
I've got the following problem: Our product is delivered with SQL2000 and SQL2005.
Now, there are some schema changes, which I'd like to deploy with T-SQL on the publishers. With SQL2000 I do it with the sp_addmergecolumn etc and on SQL 2005 (if replication compatibility level is 90) with replication of DDL. So far so good.
But how can my T-SQL Script determine, wether the replication of DDL is on? I know there exists sp_helpmergepublication, but how do I get the column replicate_ddl of the result-set?
thanks for your advices.

I am using a merge publication set to synchronize schema changes. Why am I getting the following message when I try to sync after having added columns in the publication database using ALTER TABLE statements?
The schema definition of the destination table ... in the subscription database does not match the schema definition of the source table in the publication database. Reinitialize the subscription without a snapshot after ensuring that the schema definition of the destination table is the same as the source table.
Also, why doesn't reinitializing the subscription with @upload_first = false not fix the problem?

I'm trying to set up a merge replication. Publication is created successfully and snapshot also, but when I create pull subscription on subscriber server and merge agent starts, after some time I get an error message of this type:
The schema script '\ANILREPLDATAuncANIL_BEJK_BEJK20070625142735dl_HF_vMSCene_3836.sch' could not be propagated to the subscriber.
It seams there is a problem with certain Views and SPs, because tables are successfully created, and some Views and SPs also.
I tried to exclude problematic articles, but every time another one pops up. Up until now, I excluded 7 articles from publication (1 Stored Procedure and 6 Views) but I still get errors.
I gave up because I can't exclude half of the Views and SPs just to make it work.
Is there something that can be done to solve this problem?
Thanks!

Question re Merge rep (pull) and processing order.  We have a group of changes associated with an app upgrade, the scripts run fine on the publisher.   Part of the change includes creation of a new table , followed by altering a view to use new table.Following the change at the publisher, when the sync is kicked off from the subscriber, it fails - the alter of the view throws an'invalid object' error with regard to the new table. Seems as if the view alter is attempted before the dependant table has been created.Â
I have tried to amend the processing order of the view using sp_changearticle, which executes (quickly) with a 0 return code.But it is to no avail , the error still occurs.  is it possible to change the processing order for a view article , which will be applied to schema changes ? Have

I have a problem with sql server merge replication in sql server 2000.
If my db owner €œdbo€? and replication setup under €œsa€? account it works with out any problem. But when I use another db owner it can not work properly.
For an example I have customer table ([dbo]. [Customer]) When I setup merge replication under sa account it€™s work properly.
Again I was setup merge replication using another db owner ([INV]. [Customer]) It doesn€™t work.

Hi there,
We have a big problem here with merge replication, specifically whenever a schema change occurs. We are replicating schema changes, and triggers/stored procedures. The example is that we changed about 150 stored procedures and about 30 triggers. This is then replicated to the subscriber database (which is also a merge publisher for further remote systems that were offline at the time) over a 10Mb link - hardly low bandwidth. However, the replication process takes about an hour and a half - considering the SQL on the primary server took less than a minute to run this is a big suprise.
We've run a trace to see if we can identitfy what is going on. There seems to be a great number of calls to sp_MSunmarkschemaobject - we are still waiting for a trace to complete to fully analyse this however it looks like it calls this repeatedly for every stored procedure in the database. We are currently re-testing to one of the remote servers with the merge agent set to the slow profile (not much hope that this will alter the poor performance).
This task looks to be excessive - and certainly does not seem to function in a sensible manner. Has anyone else had similar issues or have any suggestions. This is very infuriating as it means that the servers are effectively offline for a minimum of and hour and a half (in fact the remoter servers take over 4 hours !).
Thanks.

Locally I develop in SQL server 2005 enterprise. Recently I recreated my db on the server of my hosting company (in sql server 2005 express).I basically recreated the tables and copied the data in it.I now receive the following error when I hit the DB:The 'System.Web.Security.SqlMembershipProvider' requires a
database schema compatible with schema version '1'. However, the
current database schema is not compatible with this version. You may
need to either install a compatible schema with aspnet_regsql.exe
(available in the framework installation directory), or upgrade the
provider to a newer version.I heard something about running aspnet_regsql.exe, but I dont have that access to the DB. Also I dont know if this command does anything more than creating the membership tables and filling it with some default data...Any other solutions/thought on what this can be?Thanks!

Hello,
I would like to use SSIS tool to move the data from one database schema to another database schema.
For example:
Source table has
1. UserName (varchar 20) (no null)
2. Email (varchar 50) (can be null)
Destination table has
1. UserID (uniqueidentifier - GUID)
2. UserName (varchar 50) (no null)
3. EmailAddress (nvarchar 50) (can be null)
4. DateTime
Questions:
1. What controls do I use in my Data Flow to make data move between databases with different data types and include new value in UserID as a new GUID and DateTime as a date (GETDATE)?
OLE DB Source, OLE DB Destination, Data Converson and .....
How do I insert Guid and Date at the same time?
2. I have many tables to do data moving. Any sugestions? How do I architect my project? If I create many data flows for each table - it will look complicated.
Please give me some advices here.
Thanks.

I have database on SQL Server 2000 set up with a merge publication.This publication is configured with a number of dynamic filters toreduce the amount of data sent to each client. Each client has ananonymous pull subscription. The merge process can be triggered by thewindows sync manager and my application.To improve performance I have created some helper tables to hold themapping between user login and primary keys of selected entities.For the replicated data to be correct the contents of the helper tablesneeds to be up to date.I need to fire off a stored procedure on the publisher beforereplication starts to verify that this data is up to date. I can notsee any documented way of doing this however I have been experimentingwith some unorthodox systems.Firstly has anyone any ideas?I have been considering adding a trigger to some of the tables used bythe Microsoft replication code - yes I know this is very nasty.My problems arise because executing this stored procedure will causesome data to be updated. In updating data we could create a newgeneration in the database. I must therefore run my stored procedurebefore any the Microsoft code makes any generation checks / updates.Anyone done anything similar, Anyone have any better ideas?Any comments would be gratefully received.

Hi,
I'm using merge replication to maintain a backup copy of my main (publisher)MSDE database. A push subscription periodically (1 per minute) updates the backup DB.
It's intended that if the main db goes down then the backup (subscription) db can be configured as a publisher. This must all be performed via scripting.
The initial configuration of the main publisher and subscription is controlled via scripting, which works fine.
The problems occur when I try to configure the subsciber to become a publisher. A script is executed on the subscriber but fails at the point when it's configuring the publisher detail. The error is something like "unable to configure a publication for a database setup as an anonymous subscription".
I'm guessing that there are subscritpion artifacts added to the database which need to be removed before it can be configured as a new publisher.
Please help,
Jez W

I know in SQL Server the terms Database and Catalog are usedinterchangably. But a table is also assigned a schema. As seen in theINFORMATION_SCHEMA.Tables View. I don't get what this schema qualifieris all about. Like if a table has a schema of dbo.Can someone explain the relationship the schema has and what it is?Thanks.

I have setup merge replication between two machines and the data seems to be updating when changed on either side ok. However I am now looking at how I can handle schema changes. I have found on msdn (although not tried) stored procedures that will add and remove columns, but what happens if I want to delete a table for example.
At the moment I can deselect the table being deleted from being published and then delete it or modify it in Management Studio, which then means I need to create a new snapshot which can take sometime before the change is updated on the subscriber.
Is there a better way to tackle schema updates that I have not found yet? Also, how will the subscriber cope if someone starts modifying data while synchronisation to the new snapshot is going on.
I am using SQL 2005 by the way.
Thanks
John

Hi,
I am new to SQL Server and started it with SQL Server Express.
I tried unfruitful to know about 'Schema' in SQL Server.
I have to mention it as prefix for table name in SQL query. But if it is in "dbo" schema, it is not required.

I wrote a website that hits an SQL Server DB using queries that directly acces the table name with no Schema references. (Ex: SELECT * FROM tblHelpNotes;) I have also backed the file and and somehow (I have forgotten how I managed to import it.) imported it into SQL Server Express to run at home. The problem I am having is that in order to query at home I HAVE to use the Schema or it won't work. (Ex: SELECT * FROM dbo123456.tblHelpNotes;) How can I change this so I can just hit the table directly? I have tried miserable to set up a user that uses the default schema of db123456 but I can't seem to get it to work. Any idea's to point me in the right direction?

Hi,
I have tried the following out and would appreciate feedback from experienced users regarding if the following is a good/bad approach:
After bring all the data in my Data Mart, I have created a view which has all the data in a big flat table (totally unnormalized). Then based on this BIG FLAT UNNORMALIZED VIEW :) I have created my various dimensions using the 1st option i.e. Star Schema.
Based on the little testing that I have done, I seem to be getting the correct results across various dimensions... However, can someone kindly comment on this approach and the pros/cons.

I am trying to modify a survey DB schema created by OOP(Object Oriented Programming) snobs who had their heads so far up their butts(in my opinion).
This is current schema created by them.
Diagram 1 (OOP snobs version)
http://us.f3.yahoofs.com/users/41a4fde6zcff655d9/a2ae/__sr_/2761.jpg?phsEJvBB3t1v7URD
Actually there aren't a several foreign keys as they are shown in the picture, but that's what they(OOP snobs) are doing to the table "Response". They are inserting question_collection_id and its name as well as question_id and its name to Response table. However, it was not ill-intended, "We just wanted to load the report quickly"(OOP snobs).
But I really recommend this schema, Because of its simplicity.
Diagram 2 (My version)
http://us.f3.yahoofs.com/users/41a4fde6zcff655d9/a2ae/__sr_/e890.jpg?phrEJvBBF0.lGY5Y
Yet I haven't proven that my schema will provide report just as quickly as OOP snobs' version. As mentioned earlier, since they don't have foreign key constraints accordingly, I do find quite number of discrepancy on values of "question" columns between "Question" and "Response" tables and "question_collection" columns between "question_collection" and "Response" table. I can provide schedule task to eliminate those problems. But I really prefer my schema than theirs. So far, I can explain mine is better just because of its simplicity and DBA's gut instinct. I'd like to hear Superior Expert's opinion which schema is better and why one is better than the other.
Attached is also zip files of schema images if you can't see them by those URL.
