问题 I'm developing a Windows Forms application using Visual Studio 2008 C# that uses an SQL Server Compact 3.5 database on the client. The client will most likely be 32 bit Windows XP or Windows Vista machines. I'm using a standard Windows Installer project that creates an MSI file and setup.exe to install the application on a client machine. I'm new to SQL Server Compact, so I haven't had to distribute a client database like this before now. When I run the setup.exe (on new Windows XP 32 bit

How to connect to SQL Server Compact Edition 4.0 with a type provider in F#?

[亡魂溺海] 提交于 2019-12-06 01:45:49
问题 I'm attempting to connect to a SQL Server Compact Edition database from F#, and attempting to use a type provider. This is in the Visual Studio 11 Beta, so I realize there might be an issue because of that, but I think it's more likely that I just don't have the know-how yet. However, I have noticed that there's no CE-specific type provider in Microsoft.FSharp.Data.TypeProviders and I'm unsure that a regular SqlDataConnection will do the trick, so that may be the issue right there. However,

Generating Entity Keys

谁说我不能喝 提交于 2019-12-06 01:41:36
I have run into my first dissapointment with Entity Framework 4. It turns out that SQL CE, when used with EF4, does not support autogenerated primary keys . I get a System.Data.UpdateException from OnjectContext.SaveChanges() with this message: Server-generated keys and server-generated values are not supported by SQL Server Compact. So, now I have to manually generate keys for my entities. Assuming I want to use auto-incremented integer keys, what is the best way to go about generating and keeping track of the keys when using Entity Framework? Thanks for your help.

Allowed character for SQL Server CE password?

蓝咒 提交于 2019-12-05 20:21:20
In a web application we develop we generate SQL Server CE database files and for those we also generate passwords. The passwords are generated using System.Web.Security.Membership.GeneratePassword(). I assumed that GeneratePassword generated suitable password strings since it uses letters, digits and symbols. On http://msdn.microsoft.com/en-us/library/aa257373(v=sql.80).aspx I find a vague statement that SQL Server CE passwords "Can contain letters, symbols, digits, or a combination." But today a password was generated that made it impossible to create the database because the connection

How to get entity change delta in EF?

问题 I need to get the list of changed fields only, the datastore is ssce so no triggers are available Is there any support in EF to get a list or to build a generic component ? 回答1: Depending on the type of context and generated entities you can do it in several different ways. In case of objects inherited from Entity or POCO you can use ObjectStateManager in case of Self-Tracking entities you can use Tracker from entity itself. please provide more details on the way how you generated context and

Same EDMX file for different Providers

风流意气都作罢 提交于 2019-12-05 17:34:43
I'm working on a project where I have a local database (SQL CE) which is used as sort of a buffer while no connection to the server exists. On the server I want to use the same database-layout. Of course I want to use the same EDMX-File which is in a Common.dll available on the Server and the Client. In the Client I have a connection string with provider=System.Data.SqlServerCe.3.5 while it is provider=System.Data.SqlClient on the server. My problem comes when I want to save sth on the Server-side: "The provider manifest given is not of type 'System.Data.SqlClient.SqlProviderManifest'." Is

The best way to check if SQL CE is installed, and if so what version?

亡梦爱人 提交于 2019-12-05 17:16:45
I've written a VB.NET application that uses SQL CE 3.5. I'm curious if anyone has any best practice or code to help check if A) SQL CE is installed and B) If so, what version. I searched msdn and google for anything but I didn't find anything helpful. I was poking around the registry and found this key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server Compact Edition\v3.5 with a string value "Version" and the data was 3.5.5692.0. So off the bat my assumption is to check for the presence of this key but it bothers me because the "3.5" key sure sounds like it's tied to the 3.5 DLL.

Converting SQL Server database to local C# database

I have created program that uses SQL Server database to store data. After a while (and lots of stored data) I have realized I don't need database on the server, local database running without server could do the job. Now I need some advice how to export, convert or whatever, SQL Server database to local (sdf) database? I'm using VS 2010 and SQL Server 2008, I also have SQL Server Management Studio. Check out the SQL Server to SQL Server Compact Edition Copy Tool available on CodeProject in C# source code: Should do just what you need: copy data from SQL Server to a SQL Server Compact Edition

Retrieve ODBC table and Insert into SQL Server CE database

本秂侑毒 提交于 2019-12-05 16:03:40
I have an ODBC connection to a database of which I need one table of data. The table has about 20 rows, and a couple thousand lines of data. I intend to insert this table into my local SQL Server CE database, where I can put it to further use. Both connections have been tested and work. My attempt was at just inserting one column to keep things simple (I'm new to C#, programming, and stackoverflow). OdbcConnection c = new OdbcConnection(ConnectionString1); SqlCeConnection d = new SqlCeConnection(ConnectionString2); c.Open(); d.Open(); string sqlC = "SELECT * FROM ODBCTABLE WHERE ODBCCOLUMN=

SQL Server CE 3.5 update row error DB_E_ERRORSOCCURRED column error is DBSTATUS_E_SCHEMAVIOLATION

若如初见. 提交于 2019-12-05 15:52:21
I am investigating moving a small and simple SQL Server database to SQL Server CE and am currently using a small prototype to investigate basic operations with SQL Server CE with the following operations in mind: (1) programmatically create a table, (2) insert new records, (3) read existing records, and (4) update existing records. The prototype is having a problem with updating existing records when using the Accessor and the bound members of the Accessor struct. The select statement works correctly returning the row along with the data. I can update the Accessor bound members however when I
