How to combine two tables class in model and invoke it to a view?

Question

I have created two class separately in a model and i have mentioned the table name and then i have combined to tables in a single class PharmaMainModel when i invoke the single class PharmaMainModel in the view the properties of the class PharmaMainModel is not working.

namespace MedeilMVC_CLOUD.Models
{
    [Table("PharmacompanyReg")]
    public class PharmaCompany
    {
        [Key]
        public int PCompanyID { get; set; }
        public string PCompanyName { get; set; }
        public string PShortName { get; set; }
        public string PCompnaytype { get; set; }
        public string PCompnaySubType { get; set; }
        public string EstdYear { get; set; }
        public string PEmail { get; set; }
        public string PAddress1 { get; set; }
        public string PAddress2 { get; set; }
        public string PPincode { get; set; }
        public int PCountry { get; set; }
        public int PState { get; set; }
        public string PCity { get; set; }
        public string PCountryCode { get; set; }
        public string PContactperson { get; set; }
        public string PDesignationID { get; set; }
        public string PMobileNo { get; set; }
        public string PPhoneNo { get; set; }
        public string PPanNo { get; set; }
        public string PTinNo { get; set; }
        public string PGSTno { get; set; }
        public string PIECCode { get; set; }
        public string TermsandConditions { get; set; }
        public string PIPAddress { get; set; }
        public string PLatitude { get; set; }
        public string PLongitude { get; set; }
        public int CreatedBy = -1;
        public DateTime CreatedDate = DateTime.UtcNow;
        public int ModifyBy = -1;
        public DateTime ModifyDate = DateTime.UtcNow;
    }


    [Table("CompanySocialNetwork")]
    public class CompanySocial
    {
        [Key]
        public int CompanySocialID { get; set; }

        public int CompanyID { get; set; }

        public string FaceBookID { get; set; }

        public string TwitterID { get; set; }

        public string linkedinID { get; set; }

        public int CreatedBy = -1;

        public DateTime CreatedDate = DateTime.UtcNow;

        public int ModifiedBy = -1;

        public DateTime ModifiedDate = DateTime.UtcNow;
    }

    public class PharmaMainModel
    {
        public PharmaCompany pharmaCompany { get; set; }
        public CompanySocial CompanySocial { get; set; }
    }
}

When i invoke single class PharmaCompany in the view the data is working fine.

But When i invoke two class in a single class PharmaMainModel is not working in the view

Edit

public ActionResult ViewPharmaCompany()
        {
            var data = pharma.PharmaCompany.SqlQuery("Select * from PharmacompanyReg ORDER BY PCompanyID  DESC").ToList();
            return View(data);
        }
