ServiceStack AutoQuery join use - ormlite-servicestack

Question

After reading the documentation, I am not sure but I have come to the conclusion that when creating QueryDb, you cannot choose the columns to join by? And I am under the impression, you must have DTO object to copy to? You cannot copy to a regular object or a dynamic object?
public class SampleAutoQueryDb : QueryDb<MailResponseDetailOrm, object>, ILeftJoin<MailResponseDetailOrm, MailResponseOrm> { }
Can anyone provide any insight on joining my MailResponseOrm to MailResponseDetailOrm. MailResponseDetailOrm has 5 fields namely the Email address. And I would like MailResponseOrm to be joined to it by Email as well. I also, for good measure do not want to alter either columnname. Would I have to create a custom implementation or a service to do this?
UPDATE
Here is my code as posted below:
[Alias("MailReportsDetail")]
public class MailResponseDetailOrm
{
public string Email { get; set; }
public int ID { get; set; }
[Alias("RespDate")]
public DateTime? AddedDateTime { get; set; }
[Alias("DLReport")]
public string Action { get; set; }
public string ActionDetail { get; set; }
public string IP { get; set; }
public string UserAgent { get; set; }
public string EmailReferrer { get; set; }
}
[Alias("MailReports")]
public class MailResponseOrm
{
public int ID { get; set; }
public string Email { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
public string City { get; set; }
public string Company { get; set; }
public string Contact { get; set; }
public string Country { get; set; }
[Alias("LastMail")]
public DateTime? ModifiedDateTime { get; set; }
[Alias("LastReport")]
public string Action { get; set; }
public DateTime? OptOut { get; set; }
public string Part { get; set; }
public string Phone { get; set; }
public string PostalCode { get; set; }
public string Source { get; set; }
public string State { get; set; }
public string Title { get; set; }

public class SampleAutoQueryDb : QueryDb<MailResponseDetailOrm> { }
public class MyQueryServices : Service
{
public IAutoQueryDb AutoQuery { get; set; }
// Override with custom implementation
public object Any(SampleAutoQueryDb query)
{
var q = AutoQuery.CreateQuery(query, base.Request);
q.Join<MailResponseDetailOrm, MailResponseOrm>((x, y) => x.Email == y.Email)
// .Select<MailResponseDetailOrm, MailResponseOrm>((x, y) => new { x.ID, y.Email })
;
return AutoQuery.Execute(query, q);
}
}

Answer 1

Joins in AutoQuery needs to use OrmLite's Joins Reference conventions and all AutoQuery Services results are returned in a Typed DTO, which by default is the table being queried or you can use the QueryDb<From,Into> base class to return a custom result of columns from multiple joined tables.
You would need to use a Custom AutoQuery Implementation or your own Service implementation if you need customizations beyond this, e.g:
public class SampleAutoQueryDb : QueryDb<MailResponseDetailOrm> { }
public class MyQueryServices : Service
{
public IAutoQueryDb AutoQuery { get; set; }
// Override with custom implementation
public object Any(SampleAutoQueryDb query)
{
var q = AutoQuery.CreateQuery(query, base.Request);
q.Join<MailResponseDetailOrm,MailResponseOrm>((x, y) => x.Email == y.Email);
return AutoQuery.Execute(query, q);
}
}

Answer 2

// The query to join 2 objects on field names not specifically set in the class.
var q = Db.From<MailResponseDetailOrm>().Join<MailResponseDetailOrm>(x,y) => x.Email = y.Email);
// Run the query
var results = Db.Select(q);
