I'm looking to find all expense reports that are in a submitted state and were submitted prior to a given date ("days"). Is there a better (faster, easier, cleaner) way to do this?
var startDate = DateTime.Now.AddDays(-days);
using (var context = new Context())
{
var data = context.tExpenseReports
.AsNoTracking()
.Where(r => context.tTransactionStatuses.FirstOrDefault(s => s.TransactionStatusID == r.tTransactions.Max(t => t.TransactionStatusID)) != null ?
context.tTransactionStatuses.FirstOrDefault(s => s.TransactionStatusID == r.tTransactions.Max(t => t.TransactionStatusID)).TransactionStatusID == IDConstants.TRANSACTION_STATUS_SUBMITTED &&
context.tTransactionHistories.FirstOrDefault(s => s.TransactionStatusID == r.tTransactions.Max(t => t.TransactionStatusID)).CreatedDatetime < startDate
: false)
.Execute()
.Select(Mapper.Map<tExpenseReport,ExpenseReport>)
.ToArray();
return data;
}
}
I am not sure I understand all your methods
But I think it will work
var sata1=( from r in context.tExpenseReports.AsNoTracking()
let max = r.tTransactions.Max(t => t.TransactionStatusID)
let s = context.tTransactionStatuses.FirstOrDefault(s => s.TransactionStatusID == max)
where s!=null
where s.CreatedDatetime < startDate
select r);
return sata1 .Execute()
.Select(Mapper.Map<tExpenseReport,ExpenseReport>)
.ToArray();
