Help please with understanding what these exceptions telling me and how I can resolve them?

I've created an application with ADO.NET. The project debugger don't show any errors, though, during run time I receive these exceptions. I guess I am messing some lines of code I wrote in the 'PersonkartotekDBUtil.cs file, inside this method 'GetFullContactPersonTreeDB'. Here what I am trying to do is to show a full person overview info with connecting properties of Person directory through JOIN principles.

Can anyone correct me please?

The method that I suspect not being functional is:

public void GetFullContactPersonTreeDB(ref Person fcpt)
    {
        string fullPersonkartotek = @"SELECT  Person.PersonId, Person.FirstName, Person.MiddleName, Person.LastName, Person.Email, Person.Notes, Person.PrimaryAddress, Person.AlternativeAddresses, Person.TelefonNumbers
                                          Address.AddressID, Address.StreetName, Address.HouseNumber, Address.PostNr, Address.PersonPrimary, Person.AlternativePerson
                                          PostNr.PostNrID, PostNr.PostNumber, PostNr._Country, PostNr._City
                                          City.CityID, City.CityName,
                                          Country.CountryID, Country.CountryCode, Country.CountryName,
                                          Telefon.TelefonID, Telefon.Number, Telefon.TelefonType, Telefon.TelefonProvider, 
                                          Provider.ProviderID, Provider.ProviderName

            FROM      Person INNER JOIN
            Address ON Person.PersonId = Address.Person INNER JOIN
            Telefon ON Person.PersonID = Telefon.Person
            AlternativeAddress ON Person.PersonID = AlternativeAddress.Person
            Address ON Person.PersonID = Address.Person
            WHERE   (Person.PersonID = @PersonId)";


    }

The Error message on the console window after running the program:

    arent you missing some commas in your select statement? Just after "Person.TelefonNumbers", "Person.AlternativePerson" and "PostNr._City"? Commented Oct 8, 2018 at 20:43

    You probably have a double comma there Commented Oct 8, 2018 at 20:51

    Copy the query into SSMS. Brake the columns list in the select so that each column will be in a different row. Check visually if you see something suspicious. If not, declare the @PersonId variable and try to run it directly on SSMS. If you get an error message, double click it. This should move the caret roughly to where the problem is.

Looks like you were missing several commas and also missing an Inner join.

By running your query in Sql server management studio(SSMS) and using parse(CTRL+F5) you can highlight the problem.

Please see fixed code below. In future it's worth having consistent formatting to make your life easier. 

SELECT  Person.PersonId, Person.FirstName, Person.MiddleName, Person.LastName, Person.Email, Person.Notes, Person.PrimaryAddress, Person.AlternativeAddresses, Person.TelefonNumbers,
                                      Address.AddressID, Address.StreetName, Address.HouseNumber, Address.PostNr, Address.PersonPrimary, Person.AlternativePerson,
                                      PostNr.PostNrID, PostNr.PostNumber, PostNr._Country, PostNr._City,
                                      City.CityID, City.CityName,
                                      Country.CountryID, Country.CountryCode, Country.CountryName,
                                      Telefon.TelefonID, Telefon.Number, Telefon.TelefonType, Telefon.TelefonProvider, 
                                      Provider.ProviderID, Provider.ProviderName

        FROM      Person 
        INNER JOIN Address ON Person.PersonId = Address.Person 
        INNER JOIN Telefon ON Person.PersonID = Telefon.Person
        INNER JOIN AlternativeAddress ON Person.PersonID = AlternativeAddress.Person
        INNER JOIN   Address ON Person.PersonID = Address.Person
        WHERE   Person.PersonID = @PersonId
