I know this question it's old, but I think it's need a correct answer, I get to this questing searching for a LINQ equivalent of the IN SQL Keyword and see that the equivalent LINQ code for this query are not provided, maybe the Original author answer this question some time ago, but I leave this for other people searching in the internet: I got to answers one if you like to have Left Outer Joins: <pre><code>var query = from emp in context.Persons join ter in context.Terminations on emp.Id equals ter.IdPerson into terminations join dep in context.Departments on emp.IdDeparment equals dep.IdDepartment into departments join job in context.Jobs on emp.IdJob equals job.IdJob into jobs from ter in terminations.DefaultIfEmpty() //Does an Left Outer Join from dep in departments.DefaultIfEmpty() from job in jobs.DefaultIfEmpty() where (ter.IdTermination == null || ter.TerminationDate >= period) && (ter.HireDate <= period || emp.HireDate <=period) select new { emp.Id, emp.Name, emp.PaternalName, dep.DepartmentName, job.Title, emp.HireDate, ter.TerminationDate, TerminationHireDate=ter.HireDate }; </code></pre> one using Inner Joins <pre><code> var query = from emp in context.Persons join ter in context.Terminations on emp.Id equals ter.IdPerson join dep in context.Departments on emp.IdDeparment equals dep.IdDepartment join job in context.Jobs on emp.IdJob equals job.IdJob where (ter.IdTermination == null || ter.TerminationDate >= period) && (ter.HireDate <= period || emp.HireDate <=period) select new { emp.Id, emp.Name, emp.PaternalName, dep.DepartmentName, job.Title, emp.HireDate, ter.TerminationDate, TerminationHireDate=ter.HireDate }; </code></pre> the variable context is the Linq to SQL or Linq to Entity Context

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.
