The method 'Skip' is only supported for sorted input in LINQ to Entities

Question

What could be causing this problem?

public ActionResult Index(int page = 0)
{
    const int pageSize = 3;
    var areas = repo.FindAllAreas();
    var paginatedA         


        

Answer 1

I wanted to validate this by running the SQL equivalent of a similar LINQ skip/take query.

SELECT * FROM [table]
--order by [column] //omitted!
OFFSET 10 ROWS
FETCH NEXT 15 rows only

Note that when the order-by clause is omitted, the SQL error is much less informative:

"Invalid usage of the option NEXT in the FETCH statement."

So the "sorted input" is actually required on the database-level. Kudos to LINQ for helping developers write advanced SQL statements!
