Can I synch between a Mobile device using SqlServer Compact and desktop PC running Sql Server Express using Microsoft Synchronization Services?
View 1 Replies View Related Hi,
I'm in the planning stages of a new application and upper mgmt needs this question answered. I am planning to use SQL Mobile 2005 on the hand held devices and SQL Server 2005 as the server. What kind of hardware/configuration do I need that would allow 500 mobile devices to sync at roughly the same time? Any reccomendations on design issues is also welcome.
The business community is all on the same schedule and past experience shows that that do things in large groups. I need to plan for the worst case. Any input would be appreciated.
Thanks,
I have just upgraded from a working app for Pocket PC 2003 developed on MS SQL 2000 and VS 2003 to Mobile 5, MS SQL 2005 and VS 2005 and have been nable to get anything working.
I decided to go back to basics and just try to sync a SQL2005 and SQL mobile database by following the MS doc "Creating a mobile application with SQL Server mobile" and "Step by Step: Developing a SQL Mobile App with Visual Studio 2005 and SQL Server 2005". Unfortunately I have n't been able to get either of these 2 examlpes working either. The Database, publications, subscriptions etc are all created OK yet when I come to sync I get the following error:
"A request to send data to the computer running iis has failed"
I'd greatly appreciate it if someone could offer me any clues as how to approach this.
I have been able to use MS Sync Services to sync an MDF file & an SDF file (Works great! Very easy!).
What I would like to know is if I could sync an SDF file with another SDF file (making an SDF file a desktop DB and the other a Mobile DB)?
Thanks,

Hello Everyone,
I have a publication on a Sql 2000 (SP4) server. This publication has dynamic filtering enabled. What I want to do is create an interface which will generate a new dynamic snapshot based on filtering input from users. So far I can create the dynamic snapshot easy enough and I can see the filtered results on a Sql 2000 subscriber. However, there seems to be no way to configure a mobile database to point to the dynamic snapshot. This is easy to configure in a Sql 2000 subscription - the options are right there are on the properties page. Yet, it seems like the mobile database only points to the required unfiltered snapshot through the IIS proxy.
Is there any way to force the mobile database to use the dynamic snapshot instead?
Thanks,
Mike
Hi Everyone,

Hiya,
I have a project that requires that I filter certain data going to the mobile device via the publication based on user selected value on the mobile device. (Filter by location based on the selection of the location on the mobile prior to syncronization).
Now, our current authentication model is Windows Authentication, and changing that to Username based authentication is not feasable, and using the users account to pass that value to the database is the only way I can think of to do this... (Then filter based on username)
But then I thought that there has to be another way - such as passing a variable or parameter to the sync request during or before syncronization... Is this possible? If I could query the data being sent back up to the server, for instance, I could do so to retrieve the value I need.... Any ideas?
Any help appreciated!!

I use my Pocket PC XDA O2 mini for 2 years already and I don't have any problems when I sync it with my previous laptop which has Window XP operation system.
A few months ago, I bought a new laptop with Window Vista operation system, I could not sync my O2 mini with my PC. Then, I download Windows Mobile Device Center but my computer still could not recognize my O2 mini. My O2 mini has window mobile 2003 Second Edition Version 4.21.1088 operation system. Please let me know if you have any advices.
Thanks.
Hello,I've got 2 databases (both on MS-SQL Sever2k). One of them (remote)contains table which is often updated. For various reasons I'd like tomaintain a copy on local MSSQLServer. Is there any built-in mechanism whichallows to do such things?! I can do this manually, by examining the remotetable contents, and downloading new stuff (local table cannot be modified inany other way), but I guess that there is a smarter way. Any ideas?!ThanksPiotrek
View 1 Replies View RelatedCurrently our client has a website where they are using aspx as front end and SQL server as back end. We are developing same functionality using php and my sql.Currently 1 phase of development is finished. They are using both applications to do the job. Now in 2nd integration they are asking the data sync from one database to other.
We have decided once the user enters the aspx form the data will be stored in client sql server but we though of writing a script to enter this info into a csv file so that from our side we access that file and update in mysql.
Other than ftp any other better approaches to access that file on client server?Is there any possibility to sync databases directly?
I need some assistence here.I have two servers. One with MS SQL 2000 Standard edition and MSDE(MSdesktop engine).I need to sync my databases nightly, as a backup.Is there a cheap software that will do this? I don't want to justbackup the entire databases files b/c they are large and I'mtransfering them over DSL.I was thinking transaction logging, but I'm not sure. Is there a easyway to do this?I don't know how to accomplish this task.PLEASE HELP.
View 9 Replies View RelatedHi, I have compact sql databases which will be local on multiple users
devices. Due to space constraints, for one of the tables i have had to use
auto incrementing integer which works fine for the local database but i
would like to merge all of the users databases into a global database. The
table format can be seen below:
Code SnippetCREATE TABLE Players
(
ID UNIQUEIDENTIFIER NOT NULL PRIMARY KEY,
FirstName NVARCHAR(32),
LastName NVARCHAR(32)
);
CREATE TABLE Sessions
(
ID INTEGER NOT NULL IDENTITY,
PlayerID UNIQUEIDENTIFIER ,
SessionDateTime DATETIME,
CONSTRAINT pkSessions PRIMARY KEY (ID),
CONSTRAINT fkPlayerID FOREIGN KEY (PlayerID) REFERENCES Players(ID)
);
CREATE TABLE SessionDetail
(
SessionID INTEGER,
Time real,
Power real,
CONSTRAINT pkSessionDetail PRIMARY KEY (SessionID,StrokeTime),
CONSTRAINT fkSessionID FOREIGN KEY (SessionID) REFERENCES Sessions(ID)
);
The Players table will merge fine as GUIDs are used. However, how will the
sync capabilities of compact SQL handle the sessions table? When it pushes
the local data to the remote database will it change the Sessions.ID column
to a unique field (as no doubt lots of people will have 1, 2, 3 in their
local databases and the global database must have a unique ID), and then
transfer this changed ID back to the local database? Furthermore, if it
changes the Sessions.ID column during the merge it will also need to update
the SessionDetail.SessionID foreign key to maintain referential integrity,
is this also handled?
So my question is, how much of this sync and data merge is automated and are
there any good examples or pointers for my scenario? I cannot reasonably use
a GUID for Session.ID as there will be lots of SessionDetail entries and the
size would be far too much.
Many thanks,
Chris
I am very new to programming using Pocket PC's. I am attempting to develop a system that will allow scientist to access information while in the field. I read somewhere that the pocket pc must be connected to a PC before it can access a sqll mobile database. I am currently searching for the answer to this question to ensure that I can do what I am wanting to do.
If this is not true, which I hope it isn't, can someone show me some quick connectivity code to connect to the database. I am using VB.NET to do this programming.
Any help will be greatly appreciated.

I am using VS 2005 to develop a Pocket PC 2003 application and for some reason I dont have the ability to assign my datasource to a SQL Mobile Database?
When opening Server Explorer, right clicking Data Connection, Add New Data Source, Change Data Source, the only options I get are
Microsoft Access Database File
Microsoft ODBC Data Source
Microsoft SQL Server

and SQL Server 2005 (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppcgen/html/med302_msdn_sql_mobile.asp)
and in that tutorial when they do the exact same thing it shows a screen shot that also lists 'Microsoft SQL Server Mobile Edition'
Any ideas why I dont have that option? FYI, I have SQL Server 2005 and have installed SQL Server 2005 Mobile Edition.

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 am migrating a pocket PC application from VS 2003 to VS 2005 and a few weeks ago I hit the following problem when replicating
A SQL Mobile DLL could not be loaded. Reinstall SQL Mobile. [ DLL Name=sqlceca30.dll]
Scanning forums for help I saw that other people had had this problem and one
http://www.eggheadcafe.com/aspnet_answers/NETFrameworkCompactFramework/Feb2006/post25814466.asp
suggested that this problem could be circumvented by getting the replication object early and then continuously using the same object for subsequent replications.
I did this and it works a lot better now but ever so often I get another error which is
Native Error 28559 SQL Mobile encountered problems when opening the database
My only option at this point is to stop and start the application which cures the problem.
Hello,
I am developping a non-managed C++ application for PocketPC using a SQL Server mobile database.
The application is compiled for PocketPC 2003 and uses SQL Server Mobile v2. I use Visual Studio 2005. But I need to compile the application for Windows Mobile 5.0 devices. So I installed the WM5 SDK and had the WM5 into my project configuration.
The "ssceoledb.h" which I include incluses the "transact.h" file. But my problem is that this file is only provided with the PocketPC 2003 SDK and not in the WM5 SDK.
So I cannot use the WM5 configuration project with SQL Server. I also tried with the last SQL Server Mobile 2005 (ie v3.0) and the "ssceoledb30.h" also includes "transact.h".
Did I miss something to install ?
Do you know how I can resolve the problem ?
By advance, thank you for any answer.

Using MS VS 2005 (incl SQL Server Mobile)
MS Pocket PC 2005 SDK
I am working on a project that builds for Pocket PC on both Mobile 2003 and Mobile 5. The project uses/will use SQL Server Mobile to store local data.
Project created from new with support for both platforms. I include required header files ssceerr30.h and ssceoledb30.h.
Project builds fine in WM2003 configuration, release and debug.
When I build for WM5 the compiler cannot find the header file transact.h. This is included from within ssceoledb30.h. Same as under WM2003.
In WM2003 configuration if I highlight the ssceoledb30.h include in Visual Studio and open the header, it takes me to <Visual Studio dir>SmartDevicesSDKSQL ServerMobilev3.0. I then locate the include for transact.h and do the same, which takes me <Visual Studio dir>SDKPocketPC2003include. The file exists.
If I repeat the above 'browsing' under the WM5 configuration, ssceoledb30.h takes me to a different copy in the WM5 SDK directory. There is no diff between the file here and the other copy used by WM2003. If I attempt to open transact.h - file does not exist.
Fix (which I'm not too sure about, i.e. is it OK?) - If I copy transact.h to the WM5 SDK directory, the project builds.
Why has transact.h disappeared from WM5 SDK?
I can find no ref's to this problem anywhere. Is my installation of the WM5 SDK corrupt? What else could I be missing?
Is there a sample for SQL Server mobile (like the NorthwindOLEDB sample) that comes configured to build for WM5?
It is possible to access a Sql Server 2005 Mobile database in a VS2003 application (compact framework) ?
Thanks

I receive error 25123 on my PPC (audiovox 6600) in a reproducable way (usually) with .net 2.0 application that is using SQL CE that I wrote:
Open the application
Connect to the database
Close the applicaton
Re-Open the application
Connect to the database <-- Error occurs
I will also receive the error if my application isn't the first application launched (or very close to the first to launch).
I don't believe it's a memory issue as according to the memory manager I have plenty of memory:
At boot up only start screen items loaded: 18.46 Used 49.89 Free
Launch Resco File Explorer to click EXE: 19.18 Used 49.18 Free
Launch my application (no DB connection): 23.64 Used 44.71 Free
Connect to the DB and do select count(*) from a table with 0 rows: 26.27 Used 42.08 Free
Close the application (this.Close() on the form: 19.38 Used 48.97 Free
Relaunch App and connect to DB receive error: around 38 Used around 30 free
I was unable to reproduce the issue right now while typing this message, the last sets of numbers are from memory, and include other applications that are currently running.
The only way I have to get SQL CE to load again is to soft reset the PPC. If the application is able to connect to SQL CE at least once it is fine up till I close it and re-open the application. So it either connects and runs great, or it can't connect at all.
Any help in resolving this issue would be greatly appreciated.

Hi folks, I'm new to Windows Mobile progamming, and new to this forum. Apologies in advance if I'm asking a boneheaded question, but I've done searches and can't find anything directly applicable to my problem.
I'm currently walking through the published MS tutorial in setting up an SQL Server 2005 Mobile application that subscribes to a publication on SQL Server 2005 to exchange information.
I've gotten almost all the way through... successfully set up the server components, creating the publication, etc. On the mobile side, I've been able run the cab files to install the SQL Mobile components and to create the project, add the reference to the dll, and instantiate an engine object. It compiles.
The step in the tutorial after that, though, where you specify the data source from the "data" menu, I've got a problem. When I try to use the "new connection" dialog from choosing the data connection, "MS SQL Server Mobile Edition" doesn't show up as a choice. I've tried choosing any of the other combinations, and in teh subsequent "Connection properties" section my database, SQLMobile (as in their sample) is available, but I get an error when I choose it and click OK. Clicking on "Test Connection" gives me a connection successful message.
My guess is that something about the Mobile server side components is not installed correctly on my development machine, but honestly I have no idea how to begin to fix it. Has anyone seen this problem before and know how to resolve it?
Your time and any knowledge sharing is greatly appreciated.
Thank you,

This is a great tutorial and it's a shame one of the more important steps was missed.
In the €œCreate the snapshot user€? section you you find the steps to create the snapshot_agent account. Then in the €œCreate the snapshot folder€? section you find the share and folder permissions. However, at no point do the instructions advise you about adding the snapshot_agent to the SQL Server Logins. The result is that agent cannot perform the initial snapshot but you won't find this out until 50 steps later after Step 10 in the section €œCreate a new subscription".
To get back on track, openthe Object Explorer's Security section and add the snapshot_agent to your logins. Then using the "User Mappings", set an appropriate level for the SQLMobile database role. Once completed you then need to run the agent.
Right-click the SQLMobile publication you created and select "View Snapshot Agent status". From that dialog you can select "Start" to run the agent. When it completes, you can return to the tutorial section "Create a new subscription" and continue with the tutorial.
I am studying the tutorial in SQL Server 2005 Mobile Edition Books Online, and the topic is Creating a Mobile Application with SQL Server Mobile. I have got a problem when creating a new subscription after created a new SQL Server Mobile database. And the problem is shown below:
New Subscription Wizard
- Beginning Synchronization (Success)
- Synchronizing Data (100%) (Error)
Messages
* Failure to connect to SQL Server with provided connection information. SQL Server does not exist, access is denied because the IIS user is not a valid user on the SQL Server, or the password is incorrect.
HRESULT 0x80004005 (29061)
* 無法完æˆ?作æ¥ã€‚
- Finalizing Synchronization (Stopped)
- Saving Subscription Properties (Stopped)
Before I have met this problem, I have finished all the task. And I can browse the localhost web site by using anonymous account even I use internet explorer or browse the directly in IIS.
Does anyone can solve it?? Thank you very much~~~

Hi:
When I try and connecto to SQL CE I always get an invalid operation exception. I"m afraid that I did not follow the proper install for Orcas Beta 2. I can't remember if I was supposed to uninstall SQL Mobile 2005 first or not.
All I know is when I try and use my SQL CE I can't connecto to a DB / sdf file ?
Any help would be appreciated I"m just starting to use SQL CE.

Dear Readers,Is it possible, like in Access, to link to tables in other SQL databases that are on the same server? I have a query that I originally had in Access that queered from multiply databases. It did this by having those other tables in the other databases linked to the database that had the query.
Hi Forum, Ive been unsuccessfully trying to copy data from one table to another, very simple scenerio!
Table1 ID(PK), FirstName, Mobile, Date.
Table2 FirstName, Mobile.
The first question I have is should I fill Table2 at the insert stage OR should/do I update Table2 from Table1 as the users details are entered. ie create some kind of relationship.
Really appreciate good advice! cheers P
I have two db instances on different SQL Servers. One is my test db and the other the prod. db. Each has two tables that hold lookUp values for the entire application. I would like to keep these tables in sync. in both dbs. The prod. db would be the master. I was trying to design a trigger to insert, update, or delete the appropriate records in the test db as they were added or deleted from the prod db.
I'm getting too many prefixes errors on the script when trying to reference the table on the test db using four part naming convention.
Any ideas on how to resolve this issue? Do I need to set up a linked server to accomplish this functionality? If so, how do I setup security for a linked server?
Thanks in advance.
