Upgrading From Sqlce 3.1 To 3.5 Questions

May 21, 2007

In the readme of v3.5, it mentions that if I use 3.5 to open a database file created by previous version, the version number will be updated to 3.5, so I opened it in c# and run some select statement, then I run the verify() command and here's what's returned:

Source : d:Dataceguardian.sdf
Destination : n/a
Verifying - verMajor: 3, verMinor: 0, verBuild: 5300, verPoint: 0
Time - 2007-21-05 14:42:39.847

it seems the database file did not get updated to v3.5. Unless it's returning original info.

Then, I take this same database file and try to access from another project with v3.5 runtime + Enterprise Library, and it generates this error:

An exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in guardian.exe but was not handled in user code

Additional information: You are trying to access an older version of a SQL Server Compact Edition database. If this is a SQL Server CE 1.0 or 2.0 database, run upgrade.exe. If this is a SQL Server Compact Edition 3.0 or later database, run Compact / Repair. [ Db version = 3505053,Requested version = 3004180,File name = D:Dataceguardian.sdf ]

I am confused. Shouldn't 3.5 opens it up regardless of what version it is?

Sqlce 3.0 Vs Sqlce 2.0 Memory Issue

Feb 6, 2006

I am currently upgrading our ppc app (written in .net 2003) to .net 2005 and from sqlce 2.0 to 3.0. The new application runs out memory(storage) when handling lots of data transactions (both in case of using sqlcedatareader, and dataset ). There is no memory leak issue here, sqlce 3.0 simply uses a lot more (3 times more) memory than sqlce 2.0.

Our applicaton runs fine using sqlce 2.0 and .net 2003, but fail due to memory shortage

with the upgrades(which has the same code). Anyone can shed some lights on this issue?

How Do You Use The Upgrade.exe For Sqlce 2.0 To Sqlce 3.0?

Jun 9, 2006

Does anyone have any instructions on how to go about uprading a .sdf file
from sqlce 2.0 to sqlce 3.0?

I found this on an msdn website
(link: http://www.microsoft.com/sql/editions/sqlmobile/upgrading.mspx) but
as you can see its very lacking on detail. (I included the link and content
referring to upgrading the database files so you won't have to go to the link
to see the part referring to upgrading the database.) I tried to run the upgrade.exe on my device but it doesn't explain how you're supposed to point it to the .sdf that you are trying to update. Here is the content on the above web page.

Upgrading Database Files
You can upgrade a database created with an earlier version of SQL Server CE
2.0 to a database created with SQL Server Mobile by using the SQL Server
Mobile Database Upgrade tool (upgrade.exe). The Database Upgrade tool runs on
a smart device.

When you run the SQL Server Mobile Database Upgrade tool, the new SQL Server
Mobile database is created on the smart device. The new database, with the
file name extension .sdf, contains all the data that was in the source
database. You need to reinitialize the upgraded database to continue using it
for replication.

Note: If you are using replication or remote data access (RDA) as a
connectivity solution before upgrading to SQL Server Mobile, you must
synchronize the source SQL Server CE database (subscription database) with
the SQL Server database (Publisher). The reason for synchronizing before
upgrading to SQL Server Mobile is to ensure that any changes that exist in
the tables on the SQL Server CE database are updated on the SQL Server
database, because after the upgrade you must resubscribe or repull using the
new database.

Sqlce 3.5 Won't Run On Asp.net

Dec 12, 2007

My app is working on my local system with the vs2008 development server. It's an asp.net app and I added the line:
AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true);

So it works fine on my system. But I can't get it to work on shared hosting. I have uploaded all the sqlce 3.5 dlls to the bin directory. I am stuck at the error:

Access to the database file is not allowed. [ File name = ]

There actually is a file name in the connection string, and I set the permissions wide open on App_Data to test this.

What are the .net framework requirements for sqlce 3.5? I can't find this info anywhere.

I know sqlce 3.5 is not recommended for asp.net, but it is not the main site database but is used for a setup database utility to be installed for a windows app.

SQLCE 3.5 For X86 CE 4.2 Redistributable

Jan 31, 2008


We have over 1000 terminals running CE 4.2 on an x86 cpu currently using SQLCE 3.1.

We have just upgraded to VS 2008 and found the projects have been upgraded to reference SQL CE 3.5 - this is great, as we wish to use things like TOP etc.

However, all the distributable packages only include CAB files for CE 4.2 for the ARM Processor, or CE 5.0 for the x86. Is there a CAB package available for CE 4.2 for the x86 CPU? (please...)

Even just the relevant .DLL files would be fine as we repackage them ourselves anyway.

NativeException In SQLCE?

Oct 23, 2007

In my homegrown data layer, I added the ability to do Order By Clauses.

I do one query with an Order By clause (all 6 records in the table retrieved).
Then I do a 2nd query without an Order By (36 of around 200 records in the table retrieved)

And I'm getting Native Exceptions.

ExceptionCode: 0xc00000000c (Null Pointer I believe)
ExceptionAddresss: 0x00c3703c (looks to be in sqlcese30.dll)
Reading: 0x00000005

I ran thru with the debugger, and am finding the error happening inside of a SQLDataReader.Read() call. It's trying to read the 14th of the 36 records that the query has found.

I am all but positive I'm not closing this database connection. The problem is happening while I'm looping off the reader data I just retrieved and in this query there was no ORDER BY clause.

I'm at a loss as to what to do about this. I'm not explicitly closing any database connections, and I'm getting the data right after performing the query.

Is It Just Me Or Are There BIG Problems With SQLCE 3.0?

Oct 4, 2007


I wrote a very simple C# console application which was designed to give us a rough idea on the performance and reliability of SQLCE (the source code without metrics has been posted to this group recently). What I've found is that there are major performance and reliability issues with SQLCE 3.0 as opposed to SQLCE 2.0. Whereas SQLCE 2.0 seems to be fairly consistent in terms of it's memory usage and the amount of time taken to insert rows into the table regardless of the size of the table (to a limit, after about 300,000 records it too has major performance issues), SQLCE 3.0 seems to slow down noticably and continually use more memory even after a few thousand records are inserted and actually crashes (consistently) after 25592 records are inserted!

What gives? Based on this it would seem that SQLCE 2.0 is far preferable for an unattended device that needs an uptime of over 30 days whilst constantly (several times per minute) inserting into the database.

Thanks for your thoughts on this...

SqlCe Not For Productive Use?

Jul 30, 2007

I'm still having trouble deploying my Compact Edition application. The installation on other computers works, but if the program tries to start, i get the error message (translated from german):

"This Version of SQL Server 2005 Mobile Edition is not licencensed for productive use"

I always thought that there are no licence restriction with SQL Compact Edition.
Strangely the the programm works on some computers... as I think on all computers where Visual Studio is installed.

does that makes any sense to one of you?

thanks for any help,

Merge Replicaiton With SqlCe

Jun 3, 2004

Problem encountered:

Error Code: -2147467259
Message: A call to SQL Server Reconciler failed. [,,,,,]
Minor Err. 29006
Source: Microsoft SQL Server 2000 Windows CE Edition

Any idea what could be the possible problem?
I have been trying to search thru the internet for a resolution but most of the guides are very brief about the configuration of the merge replication in mssql2000 server.
e.g. http://msdn.microsoft.com/msdnmag/issues/03/09/DataPoints/default.aspx
This link above its recommended by Microsoft, but still doesn't really helps.

Does anybody have a step-by-step guide on configuring the merge replication in mssql? With diagrams preferred.


Is there anything wrong with these codes:

oRpl.Publisher = "HANBIN"; // HANBIN is my database server name
oRpl.PublisherLogin = "LHP";
oRpl.PublisherPassword = "<password>";

oRpl.InternetUrl = "http://hanbin/ssce/sscesa20.dll";
oRpl.InternetLogin = "IUSR_HANBIN";
oRpl.InternetPassword = ""; // do i need to put sth here?

oRpl.Subscriber = "CESubscriberTest"; // Any names will do?
oRpl.Publication = "testdbpub";
oRpl.PublisherDatabase = "testdb";

oRpl.Distributor = "HANBIN";
oRpl.DistributorLogin = "sa";
oRpl.DistributorPassword = "<password>";

Any help from any genious will greatly be appreciated.

Private Deployment Of SQLCE For C++ App

Apr 20, 2007

MSDN has examples of deploying SQLCE privately for C# and VB.NET, but that doesn't seem to translate to C++. A .NET application just loads the assembly it needs from the local directory, but from what I can tell I need to use the OLE DB driver to use SQL CE in C++. The problem is that the OLE DB driver is a COM object that (presumably) needs to be registered.

Has anyone successfully used SQLCE from C++ without registering any COM objects? I'm thinking the only way to do that would be to call DllGetObject() on the DLL and get the object manually, but I've never done this so I'd hate to waste the time if there's an easier way, or if this won't work.

SQLCE - Getting Started Questions....

Jan 31, 2007

I am trying to soak in all this information regarding SQLCE and was hoping someone could set me off in the right direction.

I have an Windows Mobile 5.0 data collection application that I need to sync with a desktop database. I will need the ability to sync 1 or more Pocket PC's with a desktop database.


1.) Assuming I need to sync the data, is using a SQLCE database on the device AND the desktop a viable solution?

2.) If not, would my only other option be to use SQL Server Express (SQL Server is not an option, $$$)?

3.) Keeping simplicity in mind, what would be my best choice of syncing technology? RDA? Merge Replication? Microsoft Synchronization Services for ADO.NET?

Generally speaking, I want to know if YOU were starting from scratch, what combination of technologies would you use?

SQLCE V3.5, VS2008 And Framework 2.0 -- Possible?

Feb 21, 2008

I was initially interested in building my small retail app on Framework 3.5, until just now when I saw the download size. I won't make a single sale with that as a prerequisite.

I would, however, like to use VS2008 for this. If I target Framework 2.0, will I still be able to use SQLCE v3.5? The new SET IDENTITY INSERT functionality is an absolute requirement. (Note: I haven't installed VS2008 yet--I'm still investigating options.)

How To Append Dataset To Sqlce??

Mar 11, 2008

I'm having a bit of a problem figuring out how to pass a dataset to sqlce to be appended to a table.

I'm using the CSVDataAdapter.dll to import from a csv file. I'm able to load the data into a dataset but from there I'm having my problem. Since the recordset is not from my table that I want to write, how can I pass the recordset for appending?

Code Snippet

Dim ds = New DataSet()
da = New CSVDataAdapter(apppath + "DBmyfile.csv", True)

'Fills the recordset with CSV file information
da.Fill(ds, "Newfile")

'display in grid
Me.DataGrid1.DataSource = ds.Tables("Newfile")

Could I use - USING?

Code Snippet

Using cmd As New SqlCeCommand("Newfile", conn)
cmd.CommandType = CommandType.TableDirect

'code to manipulate the resultset
Using ds As SqlCeResultSet = cmd.ExecuteResultSet(ResultSetOptions.Updatable)
End Using

SqlCe Memory Issue

Oct 3, 2006

Hi all, I am querying an SqlCe Database on my PDA and noticed that the device is slowly running out of memory every time I execute a query. I am using the following code:

public  SqlCeDataReader ExecuteReader(string command, params SqlCeParameter[] commandParameters)
            SqlCeDataReader reader = null;
            SqlCeCommand c = new SqlCeCommand(command, cn);
                for (int i = 0; i < commandParameters.Length; i++)
                reader = c.ExecuteReader();
                // Release resources
            return reader;

This method is a part of my 'SqlCeHelper' class that I have written.

I noticed that when I reach the line reader = c.ExecuteReader() , the memory of my device decreases by about 1%. The reader is returned to a class which makes use of it and then disposes of it by calling reader.Close(); The connection to the database is also closed properly at some point, but memory never gets released. Memory gets only released when the application terminates.

I am wondering if I am doing something wrong by not disposing of some resources. Please help!

(Also tried GC.Collect() , didn't help!)

SQLCE 3.5 Support For VS2005

May 30, 2007

Neither the SQLManagement Studio nor Visual Studio 2005 will open a 3.5 database. I understand that it's a "Orcas" technology but it works fine with vs2005 and Framework 2.0. I'm currently using VS2005 with CE 3.5 and using Rafik's Sync services, support for 3,5 would be a great help for the XSD and query creation.

Does anyone know when broader support for 3.5 will be available?

Issue With SqlCeParameter (SqlCE 3.1)

May 7, 2007

I have a simple query as follows:


Where @pPID=16700130,@pCID=43000000,@pCMD=€?=€?, and
@pObj=€?the cecum, identified by appendiceal orifice & IC valve€?

The filed OBJECT in AI_DTREE is of nvarchar(30)(of course the length of @pObj is more than 30 in my current query).

I have build the SqlCeCommand sccmd object with the above sql text and the parameters.

returnval = sccmd.ExecuteScalar();
When I execute the above statement I am getting the following error:

ex.Message = "@pObj : String truncation: max=30, len=55, value='the cecum, identified by appendiceal orifice & IC valve'."

But when I execute the same in Sql Server Management Studio against SqlCE db, it works fine and the result returnval =0.

How to overcome this SqlCeParameter issue?, for me it is difficult to messure the length of the filed before I exeuting the command.
