Question

I have the following table:

 ID Amt  Received
 -- ---- --------
 2  55   N 
 2  88   Y
 2  44   N
 3  5    N
 3  9    N
 4  5    N
 5  33   Y
 6  43   N
 7  54   N

    var result = (from rs in db.Exp
                  where rs.ID == id
                  && rs.Received == true
                  select rs).Max().Any();

Given an ID, I need to find the max Amt for a given id and then check if it is Y, if so, return true else return false.

Answer 1

This should do it;

db.Exp.
    Where(x => x.ID == id).
    OrderByDescending(x => x.Amt).
    Take(1).
    Any(x => x.Received == "Y");
