I am developing a small windows form with sqlCE. i made an installer to deploy it to another machine. I added the MyDB,sdf to the Application Folder. but when i run the application it gives me following error.
Access to the database file is not allowed. [ File name = MyDB.sdf ]
i checked the folder in program file(86) and it contain the .sdf file but can't figure it out what is the problem.
my connection string is string ConString = @"Data Source=MyDB.sdf";
any idea what i am doing wrong?
Hi. This is what i need to do:
I have a notifications table, which contains a memberid and a notificationtypeid (email, standard mail, sms, etc), as well as its own notificationid and other notification-specific fields. I need to count how many notifications of each type were sent to each member, i.e. getting a result similar to this table here:
and so on.
what's the sql query to accomplish this? thank you.
Hi all
some days ago I discovered that at the moment there is no support for SQL CE on WinRT!
Do you know if there will be a version of ce for WinRT?

Hello, sorry for my bad english:
I have an app that runs in 32-bit OS that create a SQL CE
3.5 database to load the DB in a PDA. But my client have to run the app on a 64-bit OS so i updated the sql ce to 4. But i found that
SQL Server Compact 4.0 does not have a release for Windows Mobile. So i wanted to know if sql ce 4 can create a sql ce 3.5 DB or if i can copy my data from the db 4 to 3.5?
Thank you.
This is a similar issue to the one discussed in the thread here. Basically I am unable to connect to a SQL Server Compact database from Visual Studio 2010 Ultimate. I have tried all of the steps discussed in the previous thread and posted there with no response.
I have tried uninstalling Visual Studio 2010 Ultimate using the Visual Studio uninstallation utility (VS2010_Uninstall-RTM.ENU.exe /full /netfx) and reinstalling, but this does not fix the issue. I would like to avoid having to install a new version of Windows 7 on my machine if at all possible.
The issue seems to have started around the time I began using the Microsoft Sync Framework 2.1.
Any suggestions would be greatly appreciated!

I have an odd issue with ClickOnce and SQLCE regarding the inability to load the sqlceme35.dll.
The issue I am having does not seem to be related to other issues related to the loading of 'sqlceme35.dll' that I have researched.
Details
Does this issue sound familiar to anyone? What else can I do to try and pinpoint the reason why the assemblies cannot be found in the x86 directory but are found in the main executable directory?
Thanks.
I have a 3rd party dll that reads from Sql2008 and internally maps VarChar fields to AnsiString.
I want to use the dll with SqlCe which uses NVarChar instead of VarChar ... when a method on the dll is called on a connection to the sdf I get the error:
"No mapping exists from DbType AnsiString to a known SqlDbType"
... understandably it won't automatically be able to convert unicode to the more restrictive ASCII.
Is it possible to map SqlCe DataType.NVarChar to AnsiString?
I did see this, but don't use NHibernate: http://netfrustrations.blogspot.com/2009/10/nhibernate-mapping-typeansistring.html
Thanks.
(FYI: I have been using the dll successfully ... they just changed to AnsiString recently)
Hi,
I am using SqlServer CE 3.5.1 with the SyncFramework 1.0 and EntityFramework 4.0.
Everything works fine until I update my database. After calling Context.SaveChanges() within my app the column of my Tracking "_SysTrackingContent" is empty. Before saving it was filled with values.
After a little research I found the static Method UpgradePublicTracking which seems to be the solution, but it isn't in my case.
Here the link http://technet.microsoft.com/en-us/library/system.data.sqlserverce.sqlcechangetracking.upgradepublictracking%28v=vs.97%29.aspx
Have you any hints to solve the problem?
best regards,

I am seeing SQL Server reporting deadlock errors and after some investigation, I found that they are not really deadlocks, but rather connections running into timeouts while waiting for a lock.
I have an application that uses multiple threads and connections (each thread has its own connection) to insert new data. All threads basically populate the same tables (say ORDER and ORDERITEMs), so the sequence of events is:
Apparently, SQL Server has picked Thread #3 to continue, rather than Thread #2, although it was waiting longer.
What I am seeing in my logs is that every now and then under high load a thread would starve to death waiting to be picked. Other threads that came in later get served, continue their work and finish after 200-400 msecs.
Is my understanding correct? Is there a way to influence this (other than increasing the timeout, which does not actually solve the issue)?

Hi all,
I have a small vb.net app and am using SQLCE to store the data. I have written a small sub to store a record in the DB but it seems to refuse to work. Here is the code:
Dim ConnCeSQL = New SqlCeConnection(My.Settings.CollectorConnectionString)
ConnCeSQL.Open()
Dim CmdCeSQL = New SqlCeCommand("INSERT INTO tbl_Application_Data_Collections([Name], [Building], [Room], [Room Code],[Created]) VALUES('Test','Test','Test','Test','01/02/2012')", ConnCeSQL)
CmdCeSQL.ExecuteNonQuery()
ConnCeSQL.Close()
Effectively the code seems to function but when I check the table, no record has been added. I don't receive any error messages.
I know that the code can access the table, as if I force an issue with a field name, an error comes back telling me that the column doesn't exist.
I have added a few message boxes into the code too to capture the connection state and also the number of rows affected. I can see the connection is open and that it returns 1 affected row, but no data.......
If I copy the INSERT command into the SQLCE editor within VS2008 and execute it, a new row is inserted.
I am at a loss now, to be honest.
I hope that someone can tell me what i'm doing wrong.
Many Thanks
Simon
Hi All,
Can any one give me a sql statement for sorting version numbers.
when i used the below query
SELECT [Policy ID] FROM [ITPP] ORDER BY cast('/' + replace([Policy ID] , '.', '/') + '/' as varchar(max))
eg
ITPP 1.0after ITPP 1.0 next value should be ITPP 2.0 instead ITPP 10.0 comes
Hello together,
this query works fine on MS SQL Server, but not on SQL CE:
select a.Gender
, a.Last_name
, a.first_name
, b. level
from patients a left outer join (select x.id
, x.PatID
, x. level
from level x
where x.id = (select max(x1.id)
from level x1
where x1.PatID = x.PatID )) b
on (a.PatientID = b.PatID )
Please help me, how to resolve it to work on SQL Server Compact!
Thanks

Hi,
I'm trying to update a record in a table using the below update command.
sqlcmdObj= sqlConnObj.CreateCommand();
sqlcmdObj.CommandText = "UPDATE WS_LOCATION SET Frequency = @FreqParams, LUTime = @LUTimeParams" + sWorkSpaceName + sFolderName + ", Client = '" +
htInputParams["Client"].ToString().Replace("'", "''") + "', Matter = '" +
htInputParams["Matter"].ToString().Replace("'", "''") + "' WHERE WSLoc_ID = '" + strLocationId + "'";
transaction = sqlConnObj.BeginTransaction(IsolationLevel.Serializable);
sqlcmdObj.Connection = sqlConnObj
sqlcmdObj.Transaction = transaction;
SqlCeParameter FreqParams = sqlcmdObj.Parameters.Add("@FreqParams", SqlDbType.Int);
FreqParams.Value = frequency;
SqlCeParameter LUTimeParams = sqlcmdObj.Parameters.Add("@LUTimeParams", SqlDbType.DateTime);
LUTimeParams.Value = DateTime.Now;
sqlcmdObj.ExecuteNonQuery().
********************************
But ExecuteNonQuery() throws the below error message.
There was an error parsing the query. [ Token line number = 1,Token line offset = 76,Token in error = 14286 ] at System.Data.SqlServerCe.SqlCeCommand.CompileQueryPlan()
at System.Data.SqlServerCe.SqlCeCommand.ExecuteCommand(CommandBehavior behavior, String method, ResultSetOptions options)
at System.Data.SqlServerCe.SqlCeCommand.ExecuteNonQuery()
at iwovEFS.DbAccess.UpdateFrequencyTable(Hashtable htInputParams)
at iwovEFS.DbAccess.InsertIntoLocationsTable(Hashtable htInputParams, Int32& errorcode) UPDATE WS_LOCATION SET Frequency = @FreqParams, LUTime = @LUTimeParams, WSName = '汉语/漢語', FolderName = '中文', Client = '', Matter = '' WHERE WSLoc_ID = '9'
occured on InsertIntoLocationTables.
Here wsname and foldername are chineese characters. What should be the problem? How do I resolve this issue?
Thanks
I have a windows application that users SQL CE 3.5 as local store. When i install it in client machines., the SQL CE (.SDF) file is not created.
I'm sure that i have copied the dependent dll's viz., sqlceca35, sqlcecompact, sqlceer35en, sqlceoledb35, sqlceqp35, sqlcese35, system.data.sqlserverce
Any help is appreciated.
