Linq Getting Customers group by date and then by their type
- by Nitin varpe
I am working on generating report for showing customer using LINQ in C#. I want to show no. of customers of each type.
There are 3 types of customer registered, guest and manager. I want to group by customers by registered date and then by type of customer. i.e If today 3 guest, 4 registered and 2 manager are inserted. and tomorrow 4,5 and 6 are registered resp. then report should show Number of customers registerd on the day . separate row for each type.
DATE TYPEOF CUSTOMER COUNT
31-10-2013 GUEST 3
31-10-2013 REGISTERED 4
31-10-2013 MANAGER 2
30-10-2013 GUEST 5
30-10-2013 REGISTERED 10
30-10-2013 MANAGER 3
LIKE THIS .
var subquery = from eat in _customerRepo.Table
group eat by new { yy = eat.CreatedOnUTC.Value.Year, mm = eat.CreatedOnUTC.Value.Month, dd = eat.CreatedOnUTC.Value.Day } into g
select new { Id = g.Min(x => x.Id) };
var query = from c in _customerRepo.Table
join cin in subquery.Distinct() on c.Id equals cin.Id
select c;
By above query I get minimum cutomers registerd on that day
Thanks in advance
