SELECT month(createdon) as monthNo, (CASE WHEN StateCode = '0' THEN 'Active' WHEN StateCode = '2' THEN 'Paid' WHEN StateCode = '3' THEN 'Cancelled' END) as StateText, (CASE WHEN StatusCode = '1' THEN 'New' WHEN StatusCode = '4' THEN 'Billed' WHEN StatusCode = '100001' THEN 'Complete' WHEN StatusCode = '100002' THEN 'Parial' WHEN StatusCode = '100003' THEN 'Canceled' END ) as StatusText, StateCode, StatusCode, count([TotalAmount]) as InvoiceCount FROM [dbo].[Invoice] WHERE year(createdon) = 2012 group by month(createdon), StateCode, StatusCode order by month(createdon),StateCode, StatusCode ;
