PC SQL Server Table (with A Column Classified Unique) Synchronizes (using Merge) With 2 PPCs SQL Mobile Adding The Same Record
Aug 29, 2006
Hi, I have a doubt about the behaviour of SQL Server 2005 in the situation I'm going to describe you.
Suppose that you have a SQL Server 2005 database on your PC, and suppose that this database has a table with a column classified as "unique" (so it's impossible for this table to contain 2 records having the same value in this column).
Suppose that you publish this database and you create 2 SQL Server Mobile 2005 subscriptions on 2 Pocket PCs.
Suppose now that the first PPC (using an embedded program) creates a record with a certain value for the column (and adds it to the table), and the second PPC makes the same thing (it inserts a record with the same column value of the first PPC).
At this point, you connect the 2 PPCs to your PC (one by one, of course), to synchronize (using merge replication) the databases...
WHAT HAPPENS??? Does an error raise?
Must you give a publication setting in which you say that, if this situation occurs, PC SQL Server holds the last (or the first, as you decide) record acquired? Is it possible?
Thank you very much

I am running VS 2005 Professional Edition
Windows XP profession with Service Pack 2
SQL Server 2005 Developer Edition.
WHAT I HAVE DONE:
I have a database running in an instance of SQL Server.
I set this up for merge publication and then set up a SQL Server Mobile Edition Subscription to that publication. After a few oversights I got everything working. The Mobile database replicated just fine. I went back verified all data was there. Can make queries to it.
PROBLEM:
I set up a new dataset to use tables from the SQL Server Mobile database. If I drag one of the tables to the dataset, VS 2005 simply stops responding. It is not using any processor. I click any place on the application and I get the Microsoft Visual Studio Delay Notification saying:
Microsoft Visual Studio is Busy.
Microsoft Visual Studio is waiting for an internal operation to complete. If you regularly encounter this delay during normal usage, please report this problem to Microsoft.
Well... It is more than just a delay. The environment is not using any processor its just sitting here. And I left it running for 2.5 hours... so now this is becoming a big source of pain for me because I need to get that dataset working to finish my business logic. The only option I have is to Kill the process.
Hopefully someone out there can help.
Additional Services running:
IIS (Whatever version comes with Windows XP Pro. I think 5.1)
SQL Server Agent, SQL Server Integration Services, SQL Server Broswer and SQL Server FullTextSearch
UPDATE: I am editing this post with an update.
I noticed that my other tables get added to the dataset just fine. It is when I add one particular table that the entire visual studio simply stops and starts giving the delay notification. I have no idea why this happens... nor do I see any noticeable difference between this table and the rest of them. I went back and made sure that all columns types where directly supported by SQL Mobile Edition and they are.

Dear ppl,
I am writing an application for a device (MDA Pro T-Mobile) having Windows Mobile 5.0 using
-MS .NET Compact Framework 2.0 SP-1
-SQL Mobile 2005.
-VS 2005 .NET
The application uses Merge Replication. The error occurs in the Synchronise() Method of the SqlCeReplication object.
"SQL Server Mobile encountered problems when opening the database."
repl.AddSubscription(AddOption.CreateDatabase);
repl.Synchronize();
I don't understand why I am having this error. It does create the database on AddSubscription() method but it is failing opening the database on Synchronise(). I have also tried uninstalling and then reinstalling all the SQL Mobile components in the following order.
-sqlce30.wce5.armv4i.cab
-sqlce30.repl.wce5.armv4i.cab
-sqlce30.dev.ENU.wce5.armv4i.cab
However, when i run this application on a device(Dell X50 AXIM) with Pocket PC 2003, it runs fine creating the database and sysnchronising it.
The target platform for the project is Windows Mobile 5.0 Pocket PC SDK.
Does any one have any clue what could be the problem ?
Regards
Nabeel

I have been atempting for days to figure this out.
I have this set up: (See Below)
The Problem I am having is occuring at the Table named OU in Maroon below.
It combines 2 chains of keys into one table to try and make a unique record.
The problem is that it is not.
Pasted below is a Query run on the data within the tables:
As you can see certain data is getting duplicated in this tabel.
I want 1 Unique record in the OU table based upon the Study ID Primary Key and the zCombined Primary Key.
Any Ideas as to what is wrong, or how to make it work would defineatly be appreciated.

I have a situation that I need to add a field to a table over linked server. The specifications of this is dynamic and it is being done in TQL / Stored procedures and this can not change. My code is generating the statement just fine and if I copy paste it to a new SSMS window and execute it WORKS.. The problem is I need to dynamically generate the statement (I am doing that just fine, I THINK). THEN I need to execute the statement IN THE SPROC, this part is not working.
Here is the code:
SET @AlterSQL = @DestinationServerName + '.[' + @DestinationDBName +'].' + @DestinationSchemaName + '.sp_executesql N'' ALTER TABLE '
+ @DestinationTableName + ' ADD ' + @TempColumn + ' int' + CHAR(39)
The above Creates this when I expose it via a PRINT statement:
addb15.[FSParallel].dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int'
After I create the statement I use:
EXEC @AlterSQL
And this returns the following error:
Msg 2812, Level 16, State 62, Procedure ETLDynamicImport, Line 244
Could not find stored procedure 'FSParallel.dbo.sp_executesql N' ALTER TABLE Node ADD ImportIdentity int''.

I want fetch studentname along with teachername,day and subject whose cid = 1 here is my query
select Student.Sname,TeacherName, Day,subject
from StudentTeacherRelation
inner join Student
Student.id = StudentTeacherRelation.StuId
where cid = 1
I want place result of it in temp,Want fetch max(id) from temp table by doing group by on Sname and Subject.find all id from temp table where that id present in max id.
show
Id StdId TeacherName Day subject
where (1,2,3,4,5,6,7-- all id from temp) in (1,2,5,6,7 -- max id from temp by doing group by on Sname and subject)
So it will show record Id StdId TeacherName Day subject where id is 1,2,5,6,7.Only five record should come.How to do that?

A common partitioning scenario is when the partition column has the same value for every record in the partition, as opposed to a range of values. Am I the only person who wonders why there isn't an option to automatically partition a table based on the unique values of the partition column? Instead of defining a partition function with constants, you ought to be able to just give it the column and be done. This would be particularly valuable for tables partitioned on a weekly or monthly date; when new data is added it could simply create a new partition if one doesn't already exist.

I have a scenario where I need to add a blank column to a table that is a publisher. This table contains over 100 million records. What is the best way to add the column? In the past where I had to make an update, it breaks replication because the update would take forever as jobs are continuously updating the table so replication can't catch up.
If I alter a table and add a column, would this column automatically get picked up in replication?

Hi ,
I would like to get your advice in an issue that I am facing regarding merge replication.
The flow is like:
1) User enter his login name and password.
2) Host_name is set as the login name that the user enters.
3) Based on the HOST_NAME property after filtering user gets the records relevent only to him
(Differnet subscriber may use same mobile device).
4) He make some changes in the local sdf according to the business logic.
5) The application Syncs with server on the next login session.
My issue is when I am trying to run the application in emulator exactly at the sdf updating part the application terminates.
Error mess: Connection to Remote Device has been lost.....
If I execute the same sql insert query it works om the local sdf and master database.
Emulator used where Pocket PC 2003 SE and Windows Mobile 6 classic emulator.
I have installed 1) Visual Studio 2005 SP 1 2) net compact framework SP2.
When I comment all the code related to Sync ,application works witout any issue.
And the same application works in my "I mate kjam".
The code that I use is given below:
==========================================================================
public void Sync(string hostname, int newsub) // Parameters for HOSTNAME and flag to denote new user or existing //user.
{
SqlCeReplication repl = new SqlCeReplication();
repl.InternetUrl = @"http://231.000.000.211/Merge/sqlcesa30.dll";
repl.Publisher = @"SERVER";
repl.PublisherDatabase = @"Merge";
repl.PublisherSecurityMode = SecurityType.DBAuthentication;
repl.PublisherLogin = @"sa";
repl.PublisherPassword = @"password";
repl.Publication = @"Merge";
repl.Subscriber = @"MergeSub";
repl.HostName = hostname;
repl.SubscriberConnectionString = @"Data Source=""Program FilesMerge.sdf"";Max Database Size=128;Default Lock Escalation =100;";
try
{
if (newsub == 0)
{
if (File.Exists(@"Program FilesMerge.sdf"))
{
File.Delete(@"Program FilesMerge.sdf");
}
repl.AddSubscription(AddOption.CreateDatabase);
repl.Synchronize();
repl.Dispose();
MessageBox.Show("newuser sync Done");
}
else
{
if (!File.Exists(@"Program FilesMerge.sdf"))
{
repl.AddSubscription(AddOption.CreateDatabase);
repl.Synchronize();
repl.Dispose();
MessageBox.Show("FirstSync Done");
}
else
{
repl.Synchronize();
repl.Dispose();
MessageBox.Show("SameuserSync Done");
}
}
=================================================================================
Please advise......

Hi,
I'm currently investigating the feasibility of having SQL Mobile on a number of devices running Windows CE. These devices will have to synchronize with the server (either using merge replication or RDA) over GPRS. The problem I have is that some of these devices will never be online. Is there are a way of synching these offline devices? The model I had in mind was using a USB key (or some other storage device) to download the latest updates from an online device and transferring this data to the offline device, and vice versa e.g. from offline to online and then merging. Is this feasible?
Thanks

I am looking to create a script that will go through a table a pick out the necessary columns to create a unique record. Some of the tables that I am working with have 200 plus columns and I am not sure if I would have to list every column name in the script or if they could be dynamically referenced. I am working with a SQL server that has little next to no documentation and everytime I type to mere some tables, I get too many rows back.

Hi
I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Thanks.

We have setup a 32-bit IIS server on a 32-bit machine. Installed necessary SQL Server components (32-bit replication components). We have installed SQL Server 2005 64-bit SP1 with latest hotfixes on a 64-bit machine.
On the Mobile device we installed SQL Server 2005 Mobile.
When we start mergereplication the problem we have is error 28009 (An instance of the SQL Server Reconciler cannot be created) on the mobile device. I read allot about it, but still have a questetion.
Should this work?
I found the doc: SQL Server 2005 Upgrade Technical Resource Guide:
Note: If your upgrade involves SQL Server CE subscribers, you must perform additional actions on the IIS server. You will need to install SQL Server 2005 client connectivity components along with SQL Server Mobile Edition components on the IIS server. You will also have to replace sqlcesa30.dlll, sqlcerp30.dll, and all the replication components on the IIS server.
From this I conclude it should work or is the doc in error?
If it does not, what can we do?
32-bit SQL Server 2005 on the 64-bit machine should work. (Can a 64-bit SQL Server 2005 run alongside 32-bit SQL Server 2005?).
Beste regards,
Hans Mank

We have a unique index on the column in the PK tableand SQL Server allows you to build a FK reference even though thecolumn is not defined as the PK.Does anyone know how to create this type of FK within Erwin?Thank You

Is it possible to create a unique constraint to a column from anothertable? For example:tb_current:current_names--------------aaabbbtb_new:new_name--------cccNow I want to create a constraint on tb_new.new_name to be unique withrespect to tb_current.current_names. However, tb_new.new_name shouldnot be unique to itself. So I should not be able to insert 'aaa' totb_new.new_name. But I should be able to insert 'ccc' totb_new.new_name.Here's the script to reproduce this example:create table tb_current(current_names varchar(10))create table tb_new(new_name varchar(10))insert tb_current values ('aaa')insert tb_current values ('bbb')insert tb_new values ('ccc')select * from tb_currentselect * from tb_newinsert tb_new values ('aaa') -- this should NOT be allowedinsert tb_new values ('ccc') -- this should be allowed

The MS SQL implementation of ALTER TABLE doesn't seem to provide the before or after placement criteria I require. How is this done in MS SQL using SQL or is there a stored procedure I can use?

If on the source I have a new column, the script generated by SqlPackage.exe recreates the table on the background with moving the data into a temp storage. If the table is big, such approach can cause issues.
Example of the script is below: in the source project I added columns [MyColumn_LINE_1] and [MyColumn_LINE_5].
Is there any way I can make it generating an alter statement instead?
BEGIN TRANSACTION;
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
SET XACT_ABORT ON;
CREATE TABLE [dbo].[tmp_ms_xx_MyTable] (
[MyColumn_TYPE_CODE] CHAR (3) NOT NULL,
[Code] ....
The same script is generated regardless the table having data or not, having a clustered or nonclustered PK.

I have a table size 2078mb, number of row +530,900. Is it normal for sql to lock users out of the db when I add a column to the end of the table? I'm running SQL 7.0. The table has 4 col regular indexes. No primary keys. It locked the user out for about 10 min. I thought with SQL 7.0 this problem went away?

Can I add a column to a database table without dropping and recreating the table?
The problem is that everytime a user creates an action that requires a new table - at the moment I drop the table and recreate the table with the new column.
This requires lots of resources as I have to populate the table again.
Is there a design way I can go around this?

Hi,
I have a table used in Merge Replication. If i add a new column in that table it gives me an error for tables in which either this table is a key or this table has key from other tables "Error validating the default for column 'rowguid'." Also for views i'm getting an error
"View 'dbo.vw_TestCaseBasic': indexes and schema binding will be removed."
If i proceed further i get an error and m not able to add the column.
"It is invalid to drop the default constraint on the rowguid column that is used by merge replication.
The schema change failed during execution of an internal replication procedure. For corrective action, see the other error messages that accompany this error message.
The transaction ended in the trigger. The batch has been aborted."
Is there any solution for the same?
