    <p>First, you should change your entities, to support your relationships:</p> <pre><code>public class Person { public int PersonId { get; set; } public string Forename { get; set; } public string Surname { get; set; } // add a collection-reference to roles public virtual ICollection&lt;Role&gt; Roles { get; set; } // add a collection-reference to visites public virtual ICollection&lt;Visit&gt; Visits { get; set; } } </code></pre> <hr> <pre><code>public class Visit { public int VisitId { get; set; } public string Name {get; set;} public string VisitStatus { get; set; } public int PersonId { get; set; } public virtual Person People { get; set; } //There is a one to many relationship to person } </code></pre> <hr> <pre><code>public class Role { public Role() { People = new HashSet&lt;Person&gt;(); } [Key] public int RoleId { get; set; } public string Name { get; set; } public virtual ICollection&lt;Person&gt; People { get; set; } //There is a many to many relationship to person } </code></pre> <p>Your problem resolved now. But you can also change the query like this:</p> <pre><code>public IEnumerable&lt;VisitDetails&gt; GetGuestVisiterList(int paperId) { using (var db = _dbFactory.GetDatabase()) { return (from p in db.People where p.Roles.Any(a =&gt; a.Name == "Guest") select new GuestVisitDetails { PersonId = p.PersonId, Forename = p.Forename, Surname = p.Surname, NumberOfVisits = p.Visits.Count(v =&gt; v.VisitStatus != "Complete") }).ToList(); } } </code></pre> <p>Let me know if you have any problem or questions or need clarifications on any part. Cheers.</p>

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
