C# - Entity Framework Connection String From The Online Database?

Mar 3, 2011

I'm working on an application that is connected to the online MSSQL database and everything is working fine.The model I'm using is entity model.The problem is that I have to change the connection string from the online database to the local one,but I don't know how.Creating new model isn't an option.I tried changing the connection string in web.config,but errors are the only thing I get.

This is what I have in web.config:

<connectionStrings>
<add name="PravosudnaAkademijaEntities" connectionString="metadata=res://*
PrakModel.csdl|res://*/PrakModel.ssdl|res://*/PrakModel.msl;provider=System.Data.SqlClient;provider connection string='Data Source=HRVOJE-PC;Initial Catalog=pak_baza;Integrated Security=True" providerName="System.Data.EntityClient" />

Provider Connection String Of Entity Framework Be Substituted With A DB Connection String Already Defined In Web.config?

Feb 2, 2011

I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

Getting Entity Framework Connection String From Alternate Location?

Mar 7, 2011

How can I retrieve the Entity Framework 4 connection string from a custom config file, not web.config?

Edit: Is it reasonable to delete the default constructor generated code and recreate it in a partial class to use the pulled in connection string?

I would really like to avoid changing all references to the EF context with an overloaded method including the connection string.

@BrokenGlass: This is what we ended up with:

How To Generate A Dynamic Connection String In Entity Framework 4

Sep 27, 2010

Is it possible to choose a specific database that will be used with the entity framework? At this time, I use the connection string in the Web.Config as database authentication.

I have twelve databases, each of them has the same structure and the same stored procedure.

There is one database for each client. When a client wants to login into the system, he needs to choose his database name from a listbox.

I would like to create a dynamic connection string which will include the database name chosen by the client.

C# - How To Include Ampersand In Connection String Password After Using Entity Framework

Sep 29, 2010

I'm using Entity Framework 4 for a simple app and would like to bake my connection credentials into the following connection string:

<connectionStrings>
<add name="MyEntities"
connectionString="metadata=res://*/MyDataModel.csdl|res://*/MyDataModel.ssdl|res://*/MyDataModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=localhostDEV;Initial Catalog=MyDB;UserId=myUser;Password=jack&jill;MultipleActiveResultSets=True""
providerName="System.Data.EntityClient" />
</connectionStrings>

However, the password (which I cannot change) contains an ampersand. ASP.NET throws:
Configuration Error: An error occurred while parsing EntityName. Line XX, position YYY.

If I replace the ampersand in the password with &, I get a SqlException: Login failed for user 'myUser'. Usually this trick works, but I'm guessing that something is failing because this is technically a connection string inside a connection string.

What should I do here? Most of my classes include code like:

using (var context = new MyEntities()) {
// do work
}

Update: It turns out that the credentials I am using are a domain account, so what I really need is Integrated Security=True in the connection string rather than a password.

Encoding the ampersand as indicated in the accepted answer should work fine, though I haven't tested it.

Jan 12, 2011

how to get this options in the connection strings working, or how i must modify the entitiy framework connection string to use the odbc entry?

<add name="KA_Entities" connectionString="metadata=res://*/Models.KA_Model.csdl|res://*/Models.KA_Model.ssdl|res://*/Models.KA_Model.msl;provider=iAnywhere.Data.SQLAnywhere;provider connection string="UserID=user;Password=password;DataSourceName=Databasename""

ADO.NET :: VS 2010 - No Entity Framework Or LINQ Support For SQL Server 2000 SQLOLEDB Connection?

Sep 1, 2010

I'm working with Visual Studio 2010 and for Data Connections am connecting to a SQL Server 2000 production database. When I try to drag a table to a .dbml file, the Object Relational Designer says, "The selected object(s) use an unsupported data provider." If I try to create an .edmx file via Generate from database, then the alert is, "This server version is not supported. You must have Microsoft SQL Server 2005 or later."

So VS 2010 has no support for the Data Entity Framework or LINQ when connecting to a SQL Server 2000 database? If that is the case, what is the best data access strategy for this scenario?

Exporting Entity Framework 4 Data Model To Entity Framework 3.5?

Oct 25, 2010

Is there a way to export a EF 4.0 Data Model to EF 3.5?

I looked around and found that we are not able to access EF 4.0 from a ASP.Net 3.5 project here: [URL]

Our project is the 1st to go to .Net 4.0 using Entity Framework and we (the team) were wondering if there was a way for the other projects that "might" need to access our data that are still using the .Net 3.5 framework.

ADO.NET :: Entity Framework With Multiple Database Servers

Feb 7, 2011

We have an IVR product that reads a configuration database for callflow information. I am writing a tool for our implementation team that will allow them to add/delete/update the data in the configuration database. Once the tool is in production, the implementer will use only the production release of the tool to modify the configuration database in all four of the IVR regions (Dev, QA, Cert, and Prod). Each region has its own database with identical schemas. The tool has 'tabs' across the top for each region. If a user is currently working in the Dev region and clicks the QA tab, how do I switch my connection from the Dev db server to the QA db server?

DataSource Controls :: Use Database Instead Of MDF File With Entity Framework?

Jan 11, 2010

I transfered my data from MDF files to MS SQL Database, but I can't get it working with entity framework.

My Old connection string is:

metadata=res://*/Models.EntityModel.csdl|res://*/Models.EntityModel.ssdl|res://*/Models.EntityModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|TripsDB.mdf;Integrated Security=True;User
Instance=True;MultipleActiveResultSets=True"

I put all data from TripsDB.mdf to Trips table in local MS SQL 2008 Enterprise database. Also changed connection string to:

Server=WIESIEK;Database=Trips;Trusted_Connection=True;providerName=System.Data.SqlClient;User ID=Jan J. Roman

But my application throws System.ArgumentExceptio with message: The 'server' keyword is not supported.

on line:

private TripsDBEntities2 _entity = new TripsDBEntities2();where TripsDBEntities2 is Entity Framework instance.

Entity Framework - Connecting To Database In Server Control?

Aug 3, 2010

As a follow on from this question I'm building a custom server control to be placed on a Sharepoint 2010 master page. The idea behind this is that it will display a menu that is dynamically populated from the database. As this is a server control, I'm building it in a dll but I've run into a small snag. As it has to connect to the database, I need to store the connection string somewhere (and have it able to be configured based on target configuration (dev/test/prod). I was intending to the user the Entity Framework as my ORM but i'm confused as to where the connection string is to be stored. In a normal ASP.NET web app it goes in the web.config, but this is a server control in a external DLL.

Where do I store the connection string so that I can just build and deploy the assembly containing the server control.

EDIT:

Before I post a bounty, I have tried using an embedded resource XML file to hold the connection string and while this works, I'm curious as to if this is best practice/a better way?

I have an ASP.NET application with existing business classes and a database schema. (which I would like to keep) Currently I am using ADO.NET for the DAL, but I would like to switch to some advanced technology there for easier data retrieval.

Is EF applicable to my situation? Can I use it without splitting up my business classes and auto code generation? Can LINQ to SQL solve my problem better?

All I want to do is map my existing classes to the existing tables and dont have to handle details of the data retrieval myself.
