Hi
I want to create an rdl-report where sql server 3.5 database stands as a data source (I'm using BIDS 2008). But I can't see the sql ce 3.5 provider in the provider list. Nothing
concrete about this problem was found in the internet.
Is any solution available for this problem?
I have a table which contains many fields; there are 2 fields of string type GpsLat and GpsLon.
I am not sure how to handle the null type in SqlCe Database.
after a select-statement using LinQToSQL , I use foreach to handle the items.
I have these questions:
1) If no data enter for fields GpsLat and GpsLon.Â
   What will be the value? Null or empty ? can I use string strGpsLat = c.GpsLat?
2) If no data enter for fields GpsLat and GpsLon, What will happen in CalculateDistance() ?
   can Convert.ToDouble() handle null and empty ?
 Thanks.
foreach (var c in Cat)
   {
                         Â
      double KM = CalculateDistance(g_strFromLat, g_strFromLon, c.GpsLat, c.GpsLon);
                            Â
 }
 private double CalculateDistance(string StartLat1, string StartLon1, string Lat2, string Lon2)
      {
        GeoCoordinate start = new GeoCoordinate(Convert.ToDouble(StartLat1), Convert.ToDouble(StartLon1));
          GeoCoordinate end = new GeoCoordinate(Convert.ToDouble(Lat2), Convert.ToDouble(Lon2));
          double distance = start.GetDistanceTo(end);       Â
          double DistanceInKM = Math.Round((distance * 0.001), 2);     Â
          return DistanceInKM;       Â
      }
I need to perform a case sensitive query using my SQL Server Compact v4 database.
Since the column in question should always be treated in a case sensitive fashion I want to change the collation on it permanently. I have tried this:
ALTER TABLE Units ALTER COLUMN UnitString NVARCHAR(20) COLLATE SQL_Latin1_General_CP1_CS_AS NOT NULL
But I get am error parsing the query.
TIA
I am using sql server compact 3.5 in client machines and micrsoft sync framework 2.1 to upload the changes in the client table to an sqlexpress 2008 table. I am using the upload only sync for that table. The table has primery key.
Some times it work correctly and gives correct numbers for total records uploaded and total records fails. But some times it upload correctly and give 0 fro total records uploaded and some numbers for total records failed. Some times it stop uploading. I used conflict resolver for clientupdateserverupdate and clientupdateserverdelet and it resolves those kind of conflicts. Is it because i am using sqlexpress in the server side?
Hi,
calling Update on an SqlCeDataAdapter causes problems if the table contains a unique nullable column. The problem occurs because SqlCeParameter discards changes to its SourceColumnNullMapping property which is set by DbCommandBuilder. This leads to wrong behavior within the DbDataAdapter which can cause various exceptions depending on the column type (for example a format exception when the column is of a string type and the row to commit has a value for this cell which can't be converted to Int32). For details on this property, why it is needed and how it affects the SQL statement see this MSDN article.
Why doesn't the SqlCeParameter allow setting its SourceColumnNullMapping? Is this a bug? There seems to be no workaround without changing the data model.
I'm really looking forward to any answers!

Hi,
I have 4 columns in a table (rates) of my db viz. SrKey (int), ItemID (int) {Related with another table}, DateValidFrom (datetime), Rate(double)
I want to disallow the user from adding a new rate for a particular item on the same date.
for eg. if there is a rate say $20 for ItemID 12, valid from 09/26/2012, I want to disallow a user from entering another rate valid from 09/26/2012 for the ItemID 12. but he can enter a new rate for another item (provided he hasn't entered a rate for that item on the same date)
I am using SQL CE 4. VB 2010 express
Please help

Hi all,
I 'm writing a small Windows Application use SqlCe 3.5 as a Database.
The Application works fine as long as all DLL of SqlCe locate in the same directory (of my application file).
An now, I want to deploy my application just only one EXE file and i put all SqlCe DLL in EmbeddedResource of my project and load these DLL at runtime by using AssemblyResolve Event from Application Object.
Result:
My Application could not operate with Database.
Exception:
Unable to load the native components of SQL Server Compact corresponding to the ADO.NET provider of version 8080. Install the correct version of SQL Server Compact. Refer to KB article 974247 for more details.
Note:
As soon as i copy all DLL (The same DLL as in EmbeddedResource) in to the Directory of my application, everything work fine again.
I also use the same method to load another assembly at runtime and i get no problem.
Question:
Can anyone help me? What did i do wrong?

Hi to all,
I have a script that translates a MySQL DB to SQL Compact 3.5 with SSMA and ErikEj tools. Basically the MySQL DB is first converted to an SQL Server 2005 or 2008 DB with SQL Server Migration Assistant then the SQL Sever DB is converted to SQL Compact 3.5 withe ErikEj tools. That part works fine.
The goal of all this is to have a copy of the MySQL DB that can be used on a Windows CE 5.0 smart device.
I ran across the re-indexing problem on the first opening on WCE but behaviour is inconsistent. Sometimes the SDF is processed correctly, sometimes it crashes on the first query, sometimes it can't be opened (parameter error or alike). The re-indexing in itself is not a problem as the DB is small, it doesn't take too long (but if it can be skipped...), but the fact that the DB cannot be opened or queried is.
I must add that I regularly update the SDF on the smart device (close the connection, replace the file, re-open it) and this is when the problems occurs. I can see that doing that too fast results in the DB not being re-indexed (size doesn't change), while waiting before re-opening is not very reliable.
Is there a way to be sure that the DB can be opened and queried ?
Thanks.
Hi,
When I load the sqlceoledb40.dll on a machine without internet connectivity (using CoCreateInstance) there is a 10s delay while the system tries to check the Certificate Revocation List.
The only way around this I have found is to call WintrustSetRegPolicyFlags to set the global WTPF_IGNOREREVOKATION flag. However I do not really want to change a global setting.
SQL CE 3.5 does not have the delay. have tried 4.0sp1 and it is the same.
Is this a bug with 4.0? Is there a cleaner way around this problem?
Sample C++ code below.
Thanks - Phil
IDBInitialize* pIDBInitialize = NULL;Hello, IÂ created a simple MVC 4 web site using Visual Studio 2012 rtm.
The site uses a SQL Server Compact 4.0 Local Database created in the App-Data directory.
Everything is just standard stuff, I have done nothing fancy whatsoever.
All works fine on my machine but I am unable to deploy the database to our server.
I have searched everywhere for help but, amazingly, noone seems to know.
I imagine there must be a standard routine for deploying this database so my question is :
How is it done?
Thanking you in anticipation.

Now if there is any existing records at SQL server table at PC side it will be erased and only new record are there after perform push command.

I am using SQL server compact edition 3.5 (version 3.5.8154) OLE deployed through Windows Embedded Compact 7 platform builder. My Execute command is failing. Note, this statement works fine on Windows CE6 with SQL 3.5 version 3.5.5692.
At this line of c++ code:
m_hrLastError = pCommandText->Execute(NULL,   IID_IRowset, NULL, NULL, (IUnknown **)&pIRowset);
Execute failed:
SQL Statement: [select table_name, column_name, data_type, character_maximum_length from information_schema.columns]
OLE DB Error:
HRESULT: 80040e37,
Minor Code: 0,

How do I resolve this issue?
Thanks,

I have an Add-In to Microsoft Project 2010 that uses Microsoft SQL CE 3.5 SP2. The Add-In is built using the .net framework 4.0 and VSTO 2010. I have a customer who is using the Add-In and is getting the following exception and stack trace:
ExceptionType: System.NullReferenceException Stack Trace:Â Â Â at System.Data.SqlServerCe.SqlCeException.ToString()
  at System.String.Concat(Object arg0, Object arg1)
  at DataModel.Persistence.Db.CreateDatabase()
The null reference exception seems to occur when ToString() is called on the exception itself.
'DataModel' in this case is my code. The code for 'CreateDatabase' and the relevant using statements can be seen below. I am not able to reproduce this on my dev environment and so far as I know only one customer has experienced this issue. Additionally I have checked that they are running the appropriate version of SQL Server CE.
My question is:
 Has anyone experienced behavior like this?  Are there any suggestions on how to reproduce, diagnose, or fix?
