Question

I’ve a data table like

Date      status       recno
---------------------------------
2012      DST;Par        1
------------------------------------
2012      DST            2
--------------------------------
2012      DST            3
--------------------------------------------
2012      DST;Ts         4
-----------------------------------

Currently I have written a query like this:

var data = from b in table.AsEnumerable()
           where b.DateInterval>=fromDate && b.DateInterval<=toDate
           group b by b.Channel1_status into g                       
           select new
           {
               AccountNo=accountNumber,
               Status = statusLabels[g.Key].ToString(),
               StatusCount = g.Count(),
           };

However, it’s returning me results these results:

Result: DST-2 
        DST;par-1 and DST;Ts-1

Expected: DST-4  DST;par-1 and DST;Ts-1

Please explain to me what I’m doing wrong and how to get the expected results.

Answer 1

If you want to count all with a status starting with DST and still group the variations (DST;par, DST;ts), you could do it manually.

Something like this (not tested, but i think you get the idea):

var dst = data.FirstOrDefault(x => x.Status == "DST");
if (dst != null) {
    foreach (var group in data.Where(x => x != dst && x.Status.StartsWith("DST")) {
        dst.StatusCount += group.StatusCount;
    }
}
