如何在Asp net Mvc中合并三个表？

Question

The data reader is incompatible with the specified 'MedeilMVC_CLOUD.Models.Company'. A member of the type, 'CompanyID', does not have a corresponding column in the data reader with the same name

//View Company
public ActionResult ViewCompany()
{
    var data = dp.Company.SqlQuery("select CompanyName,ShortName,Division,ContactPerson,Designation,Email,Address1,Address2,Pincode,Country,State,City,MobileNo,PhoneNo,PanNo,TinNo,GSTno,IECCode,C.CountryName,s.StateName,C.CountryCode,C.DialingCode from CompanyRegistration AS CR LEFT JOIN VAN_SETTING.[dbo].[Country] AS C ON CR.Country=C.CountryID LEFT JOIN VAN_SETTING.[dbo].[State] AS S ON CR.State=S.StateID ORDER BY CompanyID  DESC").ToList();
    return View(data);

Answer 1

The Error message indicates the model you are reading into, has a Property named CompanyID.

I have added CompanyID in the select below, see how that goes.

//View Company
public ActionResult ViewCompany()
{
    var data = dp.Company.SqlQuery("select CompanyID, CompanyName,ShortName,Division,ContactPerson,Designation,Email,Address1,Address2,Pincode,Country,State,City,MobileNo,PhoneNo,PanNo,TinNo,GSTno,IECCode,C.CountryName,s.StateName,C.CountryCode,C.DialingCode from CompanyRegistration AS CR LEFT JOIN VAN_SETTING.[dbo].[Country] AS C ON CR.Country=C.CountryID LEFT JOIN VAN_SETTING.[dbo].[State] AS S ON CR.State=S.StateID ORDER BY CompanyID  DESC").ToList();
    return View(data);
}

You can try the bellow code. After join you need to specify the key for relation.

  var data = dp.Company.SqlQuery("select CompanyName,ShortName,Division,ContactPerson,Designation,Email,Address1,Address2,Pincode,Country,State,City,MobileNo,PhoneNo,PanNo,TinNo,GSTno,IECCode,C.CountryName,s.StateName,C.CountryCode,C.DialingCode from CompanyRegistration AS CR LEFT JOIN VAN_SETTING.[dbo].[Country] AS C ON CR.Country.Id=C.CountryID LEFT JOIN VAN_SETTING.[dbo].[State] AS S ON CR.State.Id=S.StateID ORDER BY CompanyID  DESC").ToList();
