Hello
I recently downloaded the sql mobile edition, and then I found out about the compact edition.
I understand that these are relational lite version of sql server that can run on mobile devices.
However, what is the difference between the CF and mobile edition? Why should I choice one over the other?
I have just heard about sql everywhere, seems there are all these edtions and how would you choice the right tool for the right job?
Many thanks if someone could explain further,
Steve

Hello
We currently use SQL Mobile and SQL Server 2005. We depend heavily on merge replication for data to the field handheld devices.
We are going to be starting some new projects and I was wondering about moving to SQL Compact Edition as the first step to migrating all of our applications.
I am concerned, however, about the server side and replication. If we simply deploy SQL Compact Edition will there need to be any changes to the server for replication?
Thanks,
- will

I have not seen much info on this so I thought I would ask the forum. I have VS2005, no SP1 and SQL Mobile installed on my computer. I started developing an app for Windows Mobile 5 using RDA and it appears to work fine. Now I want to know what happens to SQL Mobile if I install SQL CE. Is it going to affect my app? Do I have to install the SQL CE merge replications tools for IIS again? I already have them for SQL Mobile? Will this affect the operation of my app? It looks like the installation procedures call for installing SQL CE tools to VS2005 before installing VS2005 SP1 then install VS2005 SP1 and finally install SQL CE tools for VS2005 SP1. Any help, thoughts or experiences involving this would be appreciated.

I am confused about the version numbers for SQL Server Compact/Mobile. It _looks_ like the versions went from CE 2.0 to Mobile 2005 to CE 3.0 (or 3.1). Is this correct? In fact, I found one location the specifically said Compact Edition is the next version of Mobile. In another location I saw Compact Edition referred to as 2005 CE.
This has got me going because I am creating a Mobile/CE app and I keep getting a "Initialize SQL Server Reconciler" and the best information I can find indicates a mismatch between the server component and the client component.
So, what are the current versions of Mobile/CE? Is there a location that lists all of the components and what version they should be?
Thanks.

Hello,
there are some limitations in SQL Server 2005 Mobile Edition - e.g. there is no TRUNCATE TABLE statement, the UPDATE .. FROM clause is not allowed etc. Are these limitations in Compact Edition too? Is T-SQL in these editions functionally equal or different? Is there any comparison of T-SQL features in both editions?

I'm currently looking at adding a database to my company's WinCE 4.2 -based device, running applications coded with embedded CE 4.0. We want to start tracking potentially large quantities of user data (10K-30K 500 byte records) and are looking at a database engine to support this. The database would reside on the device although we would potentially dump the data from the devices to a central workstation that would be used to pull reports about the data across multiple devices. SQL Server Compact Edition sounds like a possible solution, but I'm unclear if it's supported on CE 4.2 or how to install it if it is. It's clearly supported on CE 5.0, but it may be a while before we upgrade to CE 5.0 or 6.0. I've seen references that say that SQL Server Compact Edition is the same as SQL Server Mobile Edition, and references that Mobile Edition is supported on CE 4.2, but I'm unclear if I can install and use SQL Server Compact Edition on CE 4.2 or if I'm on a wild goose chase. If not, can I use SQL Server Mobile Edition and migrate to SQL Server Compact Edition when we upgrade CE to 5.0 or 6.0? If not Mobile Edition, what about Microsoft SQL Server CE 2.0? Is that going too far back in the archives?
Thanks for any guidance/enlightenment you can offer.

I am moving a VS 2003 Pocket PC app to VS 2005 and when I deploy the app from Visuyal Studio 2005 two sqlce cabs are deployed (in addition to the sqlce30 ones) namely
sqlce20.dev.ppc.wce4.armv4.CAB
and
sqlce20.ppc.wce4.armv4.CAB.
Now as I have documented in another thread (SQL 2005 Mobile : The file is not a valid database file) this gives me problems when I want to access the database being produced by replication. So I'm trying to eliminate the need for these cab files.
My pocket PC application uses two of my DLLs the first of which is my Business Objects. When I deploy this to my PDA I get the following build output

I strongly suspect that it's a third party stuff from ADOCE which I'm using to access access databases on the PDA.

Hi,
I can't seem to find which SQL Server Compact Edition version is pre-installed on the Windows Mobile 6 rom.
I guess it is 3.0, but I'm not sure about it.
Another question is, if I use SQL Server Compact Edition 3.5 by deploying the .dll files as part of my application's CAB installer, will this be a problem for Windows Mobile 5 or Windows Mobile 6?
Thank you in advance,

Hello,
we've got a SQL Server 2005 which replicates with an SQL Server Compact 3.5. Every 10 to 20 synchronisations we're getting the error mentioned above. A Soft reset of the device helps to make the synchronization working again.
Why is this error happening and how can we resolve this?
BTW, we've also running system that replicates with an SQL Server Compact 3.0 without having this problems.
Thanks,

Hello,
I have an SQLServer Mobile database, and I would like to know if there is a way to upgrade it to SQLServer 2005 (.mdf) database. My database has no records in it, just the structure (tables etc). What I am actually asking is if I can create automatically a new SQLServer 2005 Database with the same structure as my existin SQLSErver Mobile database

Hello everybody,
Wrote before but did not go any answer , try again.
I have two question about SQL compact edition (SQLCE) (.sdf) and SQL Express edition (SQLED) (.mdf).
I have been testing SQLED and have many tables and data in it.
I want know to test SQLCD and hopefully be able to communicate with the SQLED.
For this reason I was wondering the following:
1. IIs it possible to move all the tables and it constratints into the SQLCE from the SQED ?
2. Another possibility I was thinking about was to use some tables in the SQLED in the SQLCE and move data between these two databases through RDA .
However, does this two versions aloud this kind of communciation...between them....?
Thanks in forehand,
Matilde

What really changed from SQL Mobile to SQL Compact besides allowing the database to run on any desktop? Is there a document somewhere explaining the differences, I did not see anything?
I just changed my development machine over to SP1 and wondered what code I should be changing.
I am filling the database from my C++ Desktop app using ADO using the OLEDB provider Microsoft.SQLSERVER.MOBILE.OLEDB.3.0 and using System.Data.SqlServerCe in my C# mobile app. Is that OLE provider valid with the new version or should it be *.COMPACT.3.1?
I thought there was now suppose to be some sort of automatic compaction, but I did not notice any new properties.
I would appreciate any insight into the changes.
Thanks,
Juan Foegen

Hello,
I'm porting my C++ (EVC3) application from Sql CE 2.0 to Sql Mobile 3.0
(with OLE DB). To compact a 2.0 database, i used ISSCECompact interface.
But it doesn't exists with the new version. I've only found C#
and VB.Net samples in MSDN ...

Just released small piece of software with SQL Compact Edition, version 3, dll files distributed with the application.
Now feedback from 2 people suffering an error message as follows:
SQL Mobile usage is restricted on this platform. To use SQL Mobile, you must install SQL Server 2005, Visual Studio 2005, or the Tablet PC SKU.
Both using XP under Admin accounts.
My own testing did throw up this error prior to release, but only when I tried to run the program as a Limited User. I was unable to find out why. Running the program under an Administrator account never produced this error message.
The test-bed was a fresh install of XP, SP 2, running within VMware. An Administrator account was set up. No development software was installed, nor anything to do with SQL. I tried to make it a clean environment to be used by a non-technical user.
Any insights would be most appreciated.

The interface ID IID_ISSCECompact has been removed from ssceoledb30.h thus causing a compile error on this statement:
hr = m_pIUnknownProv->QueryInterface(IID_ISSCECompact, (void **) &pISSCECompact));
So how does one compact a database using the 3.0 OLEDB Provider and VC++?
Thanks

Hey guys,
So I started an SQL CE database for use inside a mobile application. I used SSMS to create a .sdf file (because if I let Visual Studio do it, SSMS can't open it because it will be version 3.5).
The reason I wanted to use SSMS is because I wanted to be able to design the database in design view, and populate it with initial information for the application to use. That means adding tables and rows.
The problem is, SSMS doesn't seem to have a design view available when working with CE databases. It also doesn't seem to have a feature for adding rows into tables. It's essentially as useless as VS2008 for designing my mobile database. It only lets me add tables, and I can't even do that visually in design view. I have to use those cumbersome forms.
Is there any way to design a CE database in design view? And add rows of data into tables? It feels like I'm overlooking something.
Note: I dont need to subscribe or publish the database. The mobile application just needs to use the database as a repository.

I've been trying to create an installer for a little .NET CF 3.5 app I've written for Windows Mobile. It uses SQL Server Compact 3.5.
I've got the .NET CF and my program to deploy on the device using ini files and ceappmgr.exe, but when I try to do the same for SQLCE 3.5, it doesn't work (more on this in a sec).
I need my installer to install across lots of different CPU architectures, so I created an ceappmgr INI file that includes all the different cabs for the different CPU architectures.
I'm trying to test the installer by making it install on my smartphone (ARM CPU). The problem is, when I install it I get an error message on the device "The installation file is not intended for this device.". I reckon this means ceappmgr is picking the wrong cab file and trying to make my phone install it!
I did a bit of testing and found out if I remove all the cabs from my ceappmgr INI file EXCEPT for the one that is appropriate for my smartphone, then it works fine! But as soon as I include a cab file that is not appropriate for my device (eg a different cpu architecture, or the ARM PPC cab file), it stops working and I get that "not intended for this device" message.
My INI file looks like this:
[CEAppManager]
Version = 1.0
Component = SQL Server Compact 3.5
[SQL Server Compact 3.5]
Description = Microsoft SQL Server Compact 3.5
CabFiles = sqlce.phone.wce5.armv4i.CAB,sqlce.wce5.armv4i.CAB,sqlce.ppc.wce5.armv4i.CAB,sqlce.wce5.mipsii.CAB,sqlce.wce5.mipsii_fp.CAB,sqlce.wce5.mipsiv.CAB,sqlce.wce5.mipsiv_fp.CAB,sqlce.wce5.sh4.CAB,sqlce.wce5.x86.CAB
Any idea why ceappmgr would be (seemingly) picking the wrong cab file and trying to make my device install it?
Btw, my smartphone uses the "sqlce.phone.wce5.armv4i.CAB" cab file.
Cheers in advance.

I am writing an application for Tablet PC's that I was planning on using SQLServer Mobile for since it is recommended to not use MSDE. HOWEVER, when I started looking at what I need to do to pull in the SQLServer Mobile for the application, I find that you have to have the Compact Framework. Is there a way to use SQLServer Mobile on a TabletPC or am I barking up the wrong tree??
Thanks.

I am writing an application that is designed for the desktop, or small group (3 or less) desktops. The application is being deployed using the Cassini web server as a complete "embedded" solution. I wanted to use SQL Server Compact because of its small footprint and because of the synchronization capabilities with SQLServer. Also, it is very easy to deploy vs. SQL Server Express. The idea behind this APP is that someone might use it locally and then decide to subscribe to the service and then connect the same application to a web services application.
That being said, and with knowledge of Microsoft's stance on SQL Compact under ASP.NET, I have most everything working and it works great except for one thing. When I add a SQLDataSource to the page and set the connection string to my file and the DataProvider to System.Data.SqlServerCe and then bind a data grid to the SQLDataSource, it runs fine on my development machine, but when I deploy to my clean test machine, I get an error when the page loads saying:
Unable to find the requested .Net Framework Data Provider. It may not be installed.
I can create a dataset in code (in fact,in several other places I do) and it works fine. It is just the SQLDataSource(s) that are throwing this error. I have a copy of System.Data.SqlServerCe.dll in the bin folder and I have all of the compact DLL's in the bin folder as well. I can't figure out what I need to do. I also have a reference to the System.Data.SqlServerCe in the web.config file.
Can anyone help?

I am using SQL Server Compact Edition under ASP.NET. I am aware of the limitations and warnings from Microsoft for SSCE under ASP.NET, but this app is designed as a desktop deployed ASP.NET application running under the Cassini web browser. I wanted to use SQL Server Compact because of the RDA capabilities with SQL Server without the overhead of installing SQL Server Express. There would be 1-3 users at most running the application. SSCE seemed to make the most sense.
That being said, I have everything working fine except for this. I have added several SQLDataSource controls to several web forms and then I have GridViews bound to these controls. I like using the controls because of the built in sorting, grouping and updating I can do. When I run this on my development machine, it runs fine. When I move to one of my clean test machines and install the app, the SQLDataSouce controls throw the following error:
Unable to find the requested .Net Framework Data Provider. It may not be installed
I have the System.Data.SqlServerCe.dll in the bin folder along with all of the files from the the SQLServer Compact 3.1 install, a reference to it in the web.config file etc. In fact, I have several other database related datasets and tableadapters that are created throughout the application and they all work fine and can access and display data from my sdf file. It seems to only be with the SQLDataSource controls.
Any help would be greatly appreciated.

I'm trying to start an application in C# with visual Studio 2008 and I want to connect it to a SQL CE 3.5 Database (local .sdf file).
I only found samples or How-to guides that use the wizard to add the datasource and the way dragging the dataset to the form. All things binded to the database where you don't have to do coding.
I don't want to have the binding navigator bar, I just want to use text box, date picker and buttons and Save that to the database myself. That way I think it will be more easy for me to validate or manipulate data before the insertion in the DB.
Some time ago a make an ASP.net that was doing same kind of thing with an Access DB...
Hope this can help to show what i really want...

Hi all.
We are developing a desktop windows forms app that uses tha database as storage for application configuration.
It may be used by one user locally OR used locally by multiple but sharing the database.
Now, i'm really sure that I have read that sharing the .sdf file over a network is supported and thus have started developing against the 3.5 compact db (sdf file).
But when testing this scenario we get a message that sharing over network is not supported. I'm really surprised and frankly puzzled since I know I have read about this being supported.
So, can someone more into this subject exlpain to this to me? Is it supported, and if not, should we use the express version instead?
Also, if we have to change strategy, is there an easy migration path regarding development (app. is not even in beta stage so no migrations will be necessary with customers.).
Thankful for any help since this might cause a lot of extra work...
If this leads down the synchronization path, could someone please explain how this is set up. Is it one "master" that acts as a publisher?
If we would like to have the solution where several users access the same db-file (be it sdf or mdf), do we have any choice here?
/Regards

is it possible or not to use a dataset with that version of sql server? i have a class that access the database with some functions and one of then return a dataset. the dataset is not to be used because it does not make sense with sql server compact edition or it cannot by use at all cause sql server compact edition does not support it?
