I have an ASP.NET MVC 3 app that is using SQL Server CE 4.0 and Entity Framework 4.1 Code First. It works fine locally , but in production, it fails with the following error: The model backing the 'foobar' context has changed since the database was created. Either manually delete/update the database, or call Database.SetInitializer with an IDatabaseInitializer instance. For example, the DropCreateDatabaseIfModelChanges strategy will automatically delete and recreate the database, and optionally seed it with new data. I've verified that my application dll and database file are up-to-date on the

I have two tables. indRailType contains a list of the names paired with an ID value that I use in other tables to indicate the rail type. WO_BreakerRail contains a date column and a rail code column that corresponds to the same code in indRailType and some other data. There's a row in WO_BreakerRail for any activity on each rail type, for every date. So I could have 3 rows dated for 3/19/2010 , each row indicates a different rail code, and what happened. When I use the following LEFT OUTER JOIN , I get a table with all the types of rail, with nulls in the rows where nothing happened on the

Im using EntityFramework 6.1.0 I have 2 providers . MysqlClient and SQLServerCE, and i need to create 2 different DBContext. That forced me to create 2 configuration classes because mysql have some different things. But when i initialize the application, the Database.DefaultConnectionFactory is from the defaultConnectionFactory(config file) , and i cant specify what provider to take on the daterminated Context. How to do it? My config file: <entityFramework> <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework"> <parameters> <parameter value

I know this is similar to this question , but I'm using SQL Server CE 3.5 with a WinForms project in C#. How can I determine whether a table exists? I know the IF keyword is not supported, though EXISTS is. Does information_schema exist in CE where I can query against it? Thanks. Yes, it does exist: SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = 'TableName' As an alternative you can Query the Table and catch the Exception thrown. If there is an Exception, the Table wasn't found, else the Table exists. SELECT TOP 1 1 FROM TableName; A little and simple Performance Test had better

I started a project using SQL CE 3.5 in Visual Studio 10. But now I found out that the database is very slow. I did some testing on SQLite and thi is much faster. Is there a way that I easily can convert de SQL CE 3.5 (sdf) database to SQLite? I have a tool to "dump" an entire SQL Compact file as SQL script, that you can then run against a SQLite db - http://exportsqlce.codeplex.com Doug Currie Export CSV file(s) from SQL CE, import into SQLite, or Use ODBC to connect to both databases and move data from one to the other 来源： https://stackoverflow.com/questions/5303797/how-convert-sql-ce-3-5

As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. If you feel that this question can be improved and possibly reopened, visit the help center for guidance. Does it make sense to use SQL Server Compact for a desktop application? How much data can it handle? Is it possible to use it with multiple users? What are the constraints? What happens when database files are broken? Is it possible to programmatically

I've build a little WPF demo app which uses EF Code-First to save its data in a SQL CE 4.0 DB. It works fine unless I remove a property from a model object. For example, if I remove "HosteBy" from this class..... public class Dinner { public int DinnerID { get; set; } public string Title { get; set; } public DateTime EventDate { get; set; } public string Address { get; set; } public string HostedBy { get; set; } public virtual ICollection<RSVP> RSVPs { get; set; } } ...it throws this exception: The model backing the 'NerdDinners' context has changed since the database was created.
