My query involves multiple tables and from what I've read on Dapper, I can only find examples, that I understand at least, that query one model.
Below are my 3 classes under the Models folder:
public class User
{
public string UserName { get; set; }
public string UserId { get; set; }
public string Email { get; set; }
public string Phone { get; set; }
}
public class Date
{
public string UserName { get; set; }
public string UserCode { get; set; }
public string LastLogin { get; set; }
}
public class Photo
{
public class UserName { get; set; }
public string UserId { get; set; }
public string PhotoUrl { get; set; }
}
In my repository I have my connection code and then a method to get all the information I need, however this method is tied to the User
model only but I also need to retrieve the photo and when I try to make a compound class so I can the User
and Photo
models in the view, it gives me an error saying it expects only the User
DataView.
public List<User> GetAll()
{
using (SqlConnection cn = new SqlConnection(connectionString))
{
var allResults = cn.Query<User>("SELECT UserName, Email, Phone, (SELECT TOP 1 PhotoPath FROM Photo WHERE User.UserId = Photo.UserId) FROM User)
Your User
class does not contain property like PhotoPath
- where you expect Dapper put will new/additional value to?
You should create new class (ViewModels/UserAndPhoto.cs
for example), which contains all properties you are selecting - then Dapper will read it from database successfully.
