MVC Multiple Databases in one single domain model - asp.net-mvc

Question

I am writting an app based on Steve Sanderson's Pro Asp .Net MVC Framework, which uses a data modeling like described on Sports Store app on that book. My app works well, I use Castle project as IOC but I have two databases. The first one stores many kind of data and my clients information. The second one stores only medical data of each client. I need to create a class that returns data in clients table, located on database 1 and medical information of each client stored on database 2.
Below are my code:
My connectionstrings on web.config:
<add name="CNRConnectionString" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=CNR;Persist Security Info=True;User ID=sa;Password=#####!" providerName="System.Data.SqlClient"/>
<add name="CNRpeConnectionString" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=pe;Persist Security Info=True;User ID=sa;Password=#####!" providerName="System.Data.SqlClient"/>
My new class (just data, no table conection):
namespace DomainModel.Entities
{
public class ImprimePeriodoPaciente
{
public int CodConsulta { get; set; }
public DateTime DataConsulta { get; set; }
public string Evolucao { get; set; }
public int CodProfissional1 { get; set; }
public int CodPaciente1 { get; set; }
public string NomeProfissional { get; set; } //receives data from other db
public string NomePaciente { get; set; } //receives data from other db
public int CodProcedimento { get; set; }
public bool TagConsulta { get; set; }
public int? TagConsulta2 { get; set; }
public DateTime di { get; set; }
public DateTime df { get; set; }
}
}
This is my concrete and interface from domainmodel:
public class SqlConsultasRepository:IConsultasRepository
{
private Table<Consulta> consultasTabela;
private Table<TEvolucao> tEvolucaoTabela;
private Table<Paciente> pacientesTabela;
private Table<Funcionario> funcionariosTabela;
public SqlConsultasRepository(string connectionString)
{
consultasTabela = (new DataContext(connectionString)).GetTable<Consulta>();
tEvolucaoTabela = (new DataContext(connectionString)).GetTable<TEvolucao>();
pacientesTabela = (new DataContext(connectionString)).GetTable<Paciente>();
funcionariosTabela = (new DataContext(connectionString)).GetTable<Funcionario>();
}
public IQueryable<ImprimePeriodoPaciente> Prontuarios {
get
{
return
(
from c in consultasTabela
join p in pacientesTabela on c.CodPaciente1 equals p.CodigoPaciente //my doom
join f in funcionariosTabela on c.CodProfissional1 equals f.CodigoFuncionario //my doom
select new ImprimePeriodoPaciente
{
CodConsulta=c.CodConsulta,
DataConsulta=c.DataConsulta,
Evolucao=c.Evolucao,
NomeProfissional= f.NomeFuncionario, //my doom
NomePaciente=p.NomePaciente, //my doom
CodProfissional1=c.CodProfissional1,
CodPaciente1 = c.CodPaciente1
}
);
}
}
The code is marked with 'my doom' to show where the problem occurs.... I need to create a connectionString reference to the other database because this tables are not in current database specified by connectionString variable. I am getting error saying that the data are not from same datacontext (or shomething like that).
So, could you help?

Got my way through it based on this post:
http://dotnetprogrammingtipsbymuhil.blogspot.com.br/2009/12/query-contains-references-to-items.html
For those who get on same problem, follow above post steps.
Im my project I've created an interface to a concrete method that takes separated data from each database and put them on separated lists, as follows:
namespace DomainModel.Concrete
{
public class SqlImprimePeriodoPacientesRepository : IImprimePeriodoPacientesRepository
{
private static string cConexao = "Data Source=.\\SQLEXPRESS;Initial Catalog=CNR;Persist Security Info=True;User ID=sa;Password=23092000";
private static string cConexao2 = "Data Source=.\\SQLEXPRESS;Initial Catalog=PE;Persist Security Info=True;User ID=sa;Password=23092000";
private IConsultasRepository cRepository = new SqlConsultasRepository(cConexao2);
private IPacientesRepository pRepisotory = new SqlPacientesRepository(cConexao);
private IFuncionariosRepository fRepository = new SqlFuncionariosRepository(cConexao);
public IQueryable<ImprimePeriodoPaciente> ImprimePeriodoProntuarios//(int? codpac, DateTime? di, DateTime? df)
{
get
{
var consultas =
(
from c in cRepository.Consultas
select new
{
c.cdf,
c.cdi,
c.CodConsulta,
c.CodPaciente1,
c.CodProcedimento,
c.CodProfissional1,
c.DataConsulta,
c.df,
c.di,
c.Evolucao,
c.TagConsulta,
c.TagConsulta2
}
)
.ToList();
var pacientes =
(
from p in pRepisotory.Pacientes
select new
{
p.CodigoPaciente,
p.NomePaciente
}
)
.ToList();
var funcionarios =
(
from f in fRepository.Funcionarios
select new
{
f.CodigoFuncionario,
f.NomeFuncionario
}
)
.ToList();
var result =
(
from c in consultas
join p in pacientes on c.CodPaciente1 equals p.CodigoPaciente
join f in funcionarios on c.CodProfissional1 equals f.CodigoFuncionario
select new ImprimePeriodoPaciente
{
CodConsulta = c.CodConsulta,
DataConsulta = c.DataConsulta,
Evolucao = c.Evolucao,
NomeProfissional = f.NomeFuncionario,
NomePaciente = p.NomePaciente,
CodProfissional1 = c.CodProfissional1,
CodPaciente1 = c.CodPaciente1
}
).ToList();
return result.AsQueryable();
}
}
}
}
That method did the job on the Domain´s Model side, so the rest resides on dealing with the results.
Hope this help someone!
