I have a SQL Server CE database in my Windows CE app. I can see it (HHS.sdf) in my project in Server Explorer: ...but the Columns folders for the tables won't expand; clicking them gives me: The path property for HHS.sdf reads: Data Source=Mobile Device\Program Files\hhs\HHS.sdf If the path is not valid, why is Server Explorer showing me the database at all? If I create a new connection in Server Explorer (by selecting "Add Connection..." from the Data Connections context menu), I can navigate to the .SDF file on the device (\Program Files\hhs), test the connection in the "Add Connection"

I'm writing a simple desktop application in which I'm using a local SQL database (SQL Server CE). Here is the problematic section: SqlCeConnection conn = new SqlCeConnection("Data Source=|DataDirectory|\\App_Data\\Rosters.sdf"); System.Data.SqlServerCe.SqlCeCommand cmd = new SqlCeCommand(); cmd.Connection = conn; cmd.CommandText = String.Format("Insert into Teams (LeagueID, TeamName, Color) values ({0},'{1}','{2}');SELECT @@IDENTITY;", leagueID, txtTeamName.Text.Replace("'", "''"), txtColor.Text.Replace("'", "''")); conn.Open(); int teamID = (int)cmd.ExecuteScalar(); conn.Close(); The problem

We've got an SQL Ce database on a remote machine and we're trying to get a reporting system (using custom LINQ queries) via c# to connect to the database in shared read mode. At this point we're getting an exception "There is a file sharing violation", even when the database has no other conections. Our sql connection string appears thus: using (SqlCeConnection conn = new SqlCeConnection( "Data Source=\\\\telemetry\\C$\\users\\usermetrics.sdf; File Mode=shared read;)) { conn.Open( ); // => exception here ... Is this even possible? 来源： https://stackoverflow.com/questions/7249510/can-i-connect

I have an app in c# using Visual Studio 2010 express and realized the sqlce database i was using does not meet all of our needs. I am trying to figure out how to add a firebird datasource and point to my firebird database. I want to mimic the sqlce dataset creating a new dataset but with designer. I think my first step needs to be getting the data source added but I can't figure out how to do it. Any ideas? I tried following this article: http://www.ibprovider.com/eng/documentation/firebird_adonet/p2_visual_studio_2008.html#server_explorer as well as additional links within this article but

Being new to working with Data, I hope I'm asking this properly. How can I select what columns come in from a DataSet into a DataTable? I know I can fill a DataTable by using... DataTable table = dataSet1.Tables[0]; but this brings in all the columns. How can I fill a DataTable with only certain columns? I'm using .NET 3.5, C#, and a SQL CE 3.5 single table database. Thanks. // Assumes that connection is a valid SqlConnection object. string queryString = "SELECT CustomerID, CompanyName FROM dbo.Customers"; SqlDataAdapter adapter = new SqlDataAdapter(queryString, connection); DataSet customers

I have two DataBase Table (SQL CE). A Teacher table and a A Class table. The two tables have One-to-Many relationship where one teacher has many classes (i.e. Class has a foreign key teacher_id ). Number of teachers (rows) is inserted (or generated) through C# code in run time, so as classes Which of the following is faster in INSERT and SELECT? Each time a new teacher is INSERTed, a new Class Table is created (e.g. Class_teacher001) to store whichever classes the teacher has. In this case, each Class Table doesn't have to be so large and foreign key is not needed because table name would

I've got a SQL Server CE table like so: ...and I'm trying to update its solitary record like so: update workTables set fileType = "INV" Yet I get: Why? UPDATE Please see a related question here Your query should be: update [workTables] set [fileType] = 'INV' Note: single quotes ^^^^ Here check Microsoft support for yor error. http://support.microsoft.com/kb/825392 This is from the site: SYMPTOMS: When you run a query on a Microsoft SQL Server 2000 Windows CE Edition version 2.0 database, and the query has a column that contains one or more space characters, the query may not be successful.

Hi I have a following problem. I've created a project in 32 bit operating system. There I have installed EF 4.1 and SQL CE 4 for 32 bit. I've created a test table and launched it. Everything works, i.e. there is a connection to db and CRUD operations happen. In the reference pane I've set the copy local property for binaries EntityFramework.dll , System.Data.SqlServerCe.dll and System.Data.SqlServerCe.Entity.dll to true. Then I copy pasted the project into machine with x64 OS. It gives me the following error: Could not load file or assembly 'System.Data.SqlServerCe, Version=4.0.0.0, Culture
