Question

I have one application using MVC3 w/ Razor that has been working perfectly working with one database. I am now encountering this error when trying to access the second database:

CREATE DATABASE permission denied in database ‘master’.

I assumed adding another DbContext class to the project would be the same process I used to add the first pre-created database, so I added the second connection string to the web.config just like this:

<connectionStrings>
<add name="DbContext1" connectionString="Data Source=db1.server.com;Initial Catalog=dbName1;User Id=db1;Password=*&#!$;" providerName="System.Data.SqlClient" />
<add name="DbContext2" connectionString="Data Source=db2.server.com;Initial Catalog=dbName2;User Id=db2;Password=*&#!$;" providerName="System.Data.SqlClient" />

I then added the second DbContext class to the application:

public class DbContext1 : DbContext
{
    public DbSet<Table1> Object1 { get; set; }

    public DbSet<Table2> Object2 { get; set; }

    public DbSet<Table3> Object3 { get; set; }

    public DbSet<Table4> Object4 { get; set; }
}


public class DbContext2 : DbContext
{

    public DbSet<Table1> Object5 { get; set; }
}

The problem appears when I try to access the second database. The first database is still working like a charm, but for some reason, the second database appears to be trying to create a new database rather than read the existing database at the end of the connection string. Any help would be greatly appreciated!

Answer 1

Try explicitly selecting the context, either in the constructor of your classes:

public class DbContext1 : DbContext
{
    public DbContext1() : base("DbContext1")
    {
    }
    public DbSet<Table1> Object1 { get; set; }

    public DbSet<Table2> Object2 { get; set; }

    public DbSet<Table3> Object3 { get; set; }

    public DbSet<Table4> Object4 { get; set; }
}


public class DbContext2 : DbContext
{
    public DbContext2() : base("DbContext2")
    {
    }

    public DbSet<Table1> Object5 { get; set; }
}

Or, overloading the constructor to accept a connection string, and calling it in your code:

public class DbContext2 : DbContext
{
    public DbContext2(string connectionString)  : base (connectionString)
    {
    }

    public DbSet<Table1> Object5 { get; set; }
}

and then when you create a new context:

var context = new DbContext2("DbContext2");
