LINQ Query Multiple Group and count of latest record - Oracle DB

I tried to divided Linq queries into 3 (total, success, fail) but so far "Total" Linq query is working fine. Please help me to get "Success", "Fail" columns (it has mulitple statuses and we have to check the last column of each transaction and destination)
Note: you need to group by ProcessTime, TransactionId, Destination and check last column whether it is success or Fail then apply count (we are using oracle as backend)
LINQ for Total count
var query = (from filetrans in context.FILE_TRANSACTION
join route in context.FILE_ROUTE on filetrans.FILE_TRANID equals route.FILE_TRANID
where
filetrans.PROCESS_STRT_TIME >= fromDateFilter && filetrans.PROCESS_STRT_TIME <= toDateFilter
select new { PROCESS_STRT_TIME = DbFunctions.TruncateTime((DateTime)filetrans.PROCESS_STRT_TIME), filetrans.FILE_TRANID, route.DESTINATION }).
GroupBy(p => new { p.PROCESS_STRT_TIME, p.FILE_TRANID, p.DESTINATION });
var result = query.GroupBy(x => x.Key.PROCESS_STRT_TIME).Select(x => new { x.Key, Count = x.Count() }).ToDictionary(a => a.Key, a => a.Count);

Check this solution. If it gives wrong result, then I need more details.
var fileTransQuery =
from filetrans in context.AFRS_FILE_TRANSACTION
where accountIds.Contains(filetrans.ACNT_ID) &&
filetrans.PROCESS_STRT_TIME >= fromDateFilter && filetrans.PROCESS_STRT_TIME <= toDateFilter
select filetrans;
var routesQuery =
from filetrans in fileTransQuery
join route in context.AFRS_FILE_ROUTE on filetrans.FILE_TRANID equals route.FILE_TRANID
select route;
var lastRouteQuery =
from d in routesQuery.GroupBy(route => new { route.FILE_TRANID, route.DESTINATION })
.Select(g => new
{
g.Key.FILE_TRANID,
g.Key.DESTINATION,
ROUTE_ID = g.Max(x => x.ROUTE_ID)
})
from route in routesQuery
.Where(route => d.FILE_TRANID == route.FILE_TRANID && d.DESTINATION == route.DESTINATION && d.ROUTE_ID == route.ROUTE_ID)
select route;
var recordsQuery =
from filetrans in fileTransQuery
join route in lastRouteQuery on filetrans.FILE_TRANID equals route.FILE_TRANID
select new { filetrans.PROCESS_STRT_TIME, route.CRNT_ROUTE_FILE_STATUS_ID };
var result = recordsQuery
.GroupBy(p => DbFunctions.TruncateTime((DateTime)p.PROCESS_STRT_TIME))
.Select(g => new TrendData
{
TotalCount = g.Sum(x => x.CRNT_ROUTE_FILE_STATUS_ID != 7 && x.CRNT_ROUTE_FILE_STATUS_ID != 8 ? 1 : 0)
SucccessCount = g.Sum(x => x.CRNT_ROUTE_FILE_STATUS_ID == 7 ? 1 : 0),
FailCount = g.Sum(x => failureStatus.Contains(x.CRNT_ROUTE_FILE_STATUS_ID) ? 1 : 0),
Date = g.Min(x => x.PROCESS_STRT_TIME)
})
.OrderBy(x => x.Date)
.ToList();

Grouping week of the month that is input to linechart

I have a problem when grouping weeks from input months,
the results I get are always like this
{name: "Pembunuhan", data: [1,4]}
it should be the result I want like this
{name: "Pembunuhan", data: [1,0,0,4]}
this is my code
var dateNya = DateTime.Today;
var bln = int.Parse(month);
var mstrKategori = context.master_kategori.OrderBy("id ASC").ToList();
var joinnya = (from ls in context.list_dokumen join ktgr in context.master_kategori on ls.kategori equals ktgr.id
where ls.polda_id != null
select new
{
tgl_laporan = ls.tgl_laporan,
idKategori = ktgr.id,
week = ls.week,
month = ls.month,
year = ls.year
}).ToArray();
foreach (var itemktgr in mstrKategori)
{
var tes2 = joinnya.Where(i => i.idKategori == itemktgr.id).Where(a => a.month == bln).Where(o => o.year == dateNya.Year)
.GroupBy(row => new { week = row.week ?? 0 })
.Select(g => new
{
week = g.Key.week,
couny = g == null ? 0: g.Count()
})
.ToList();
tes2.ToList().ForEach(p => lineChartList.Add(new DataChart {name = itemktgr.nama2, data = p.couny}));
}
var result = lineChartList.GroupBy(x => new { x.name })
.Select(b => new DataChartTrending2
{
data = b.Select(bn => bn.data).ToList(),
name = (b.Key.name == null) ? "Lainnya" : b.Key.name
}).ToList();

The GroupBy clause won't create empty groups for weeks that have no matching records.
Use GroupJoin to perform an outer join on week indices, meaning that you will get a group for each week index, even indices that no record in tes2 matched:
var weekIds = Enumerable.Range(0, 4); // assuming your weeks are 0, 1, 2, 3
var tes2 = joinnya
.Where(i => i.idKategori == itemktgr.id)
.Where(a => a.month == bln)
.Where(o => o.year == dateNya.Year)
var countPerWeek = weekIds.GroupJoin(
tes2,
weekId => weekId,
row => row.week,
(week, weekGroup) => weekGroup.Count()
);
For each week, it will get you the number of matching records, including zeroes for weeks that don't have a matching record.
Alternative syntax:
var countPerWeek =
from weekId in weekIds
join row in tes2 on weekId equals row.week into weekGroup
select weekGroup.Count();

Sum values in datatable using linq based on conditions

I'm having a datatable like mentioned below.
ID Percentage
1 50
1 30
2 0
2 100
Result:
ID Percentage
1 80
2 100
I tried this and it doesn't work
var n = dt.AsEnumerable()
.Where(r => (int)r["ID"] != "0" || (int)r["ID"] != "100")
.Sum(r => (int)r["Percentage"]);
I'm new to linq and pls provide some suggestions.
Now I need to sum the percentage for each ID and the percentage for each ID should be 0 or 100 percentage.
If any one of the ID in table doesn't have 0 or 100 I need to alert. Pls suggest me how I can do this in linq and I think its the best way.

var result = from row in dt.AsEnumerable()
group row by row["ID"]
into g
select new
{
ID = g.Key,
Sum = g.Sum(x => int.Parse(x["Percentage"].ToString()))
};
var errorItems = result.Where(x => x.Sum != 100 && x.Sum != 0);
if (errorItems.Any())
{
var ids = errorItems.Select(x => x.ID);
string msg = string.Format("ID(s): [{0}] don't meet condition.", string.Join(",", ids));
MessageBox.Show(msg);
}

You are not trying get the sum of "Percentage" for the whole table so directly doing a sum on it wont give you the desired result.
You're trying to find the sum of the percentage for each ID value so you need to group it by ID.
That's what GroupBy(g => g.Field<int>("ID")) does. Then you take the group(g), and for each group, you sum the "Percentage" Column of the members i.e.. .Select(g => g.Sum(p => p.Field<int>("Percentage")))
Here is the complete code.
dt.AsEnumerable().Where(r => r.Field<int>("ID") == 0 || r.Field<int>("ID") == 100).GroupBy(g => g.Field<int>("ID")).Select(g => g.Sum(p => p.Field<int>("Percentage")));
to put an alert message you can use Any instead of the where to check for the presence of the values
if(dt.AsEnumerable().Any(r => r.Field<int>("ID") != 0 && r.Field<int>("ID") != 100)
{
Console.WriteLine("Alert");
}

I guess that you want a new DataTable with the same columns as the first but with grouped percentage by ID? Then have a look at GroupBy and Sum:
var groupQuery = dt.AsEnumerable()
.Select(r => new { ID = r.Field<int>("ID"), Percentage = r.Field<int>("Percentage") })
.Where(x => x.ID != 0 && x.ID != 100)
.GroupBy(x => x.ID);
DataTable groupingTable = dt.Clone(); // empty, same columns
foreach(var grp in groupQuery)
groupingTable.Rows.Add(grp.Key, grp.Sum(x => x.Percentage));
This presumes that the type of the columns is actually int. If they are strings the best way is to change it to int, if you can't do that you have to use int.Parse.
For example:
ID = int.Parse(r.Field<int>("ID"))`
Update: Although it's not clear what you want if i reread your qustion, especially:
If any one of the ID in table doesn't have 0 or 100 I need to alert
You could use this to get all ID-groups without 0 or 100 percentage:
var without0Or100Perc = dt.AsEnumerable()
.Select(r => new { ID = r.Field<int>("ID"), Percentage = r.Field<int>("Percentage") })
.GroupBy(x => x.ID)
.Where(g => !g.Any(x => x.Percentage == 0 || x.Percentage == 100));
Now you can use Any, FirstOrDefault or a foreach loop to consume this query, so one of following approches:
bool anyWithout0Or100Perc = without0Or100Perc.Any();
var firstWithout0Or100Perc = without0Or100Perc.FirstOrDefault();
anyWithout0Or100Perc = firstWithout0Or100Perc != null;
foreach (var grp in without0Or100Perc)
{
Console.WriteLine("ID: {0} Percentages:{1}",
grp.Key,
String.Join(",", grp.Select(x => x.Percentage)));
}

Getting a count from Linq query with group by

How can I get a count by Month from the Linq query below? An error is returned telling me that "grp.INPUT_SOURCE" doesn't exist.
var yesterday = DateTime.Today.AddDays(-365);
var Total = UPDATE_TRANSACTIONS
.Where(m => m.CREATE_DATE > yesterday)
.Where(m => m.CREATE_DATE < DateTime.Today)
.GroupBy(m=> new{m.CREATE_DATE.Value.Year, m.CREATE_DATE.Value.Month,m.CREATE_DATE.Value.Day, m.INPUT_SOURCE})
.Select(grp => new {
source = grp.INPUT_SOURCE,
Count = grp.Count()
});
Total.Dump();

It should be source = grp.Key.INPUT_SOURCE,
since that column is part of the Key

Cannot Group By on multiple columns and Count

I want to write this simple query with Linq:
select issuercode,securitycode,dataprocessingflag,COUNT(issuercode) as cnt
from cmr_invhdr
where ProcessedLike <> 'STMNT ONLY'
group by issuercode,securitycode,dataprocessingflag
order by Issuercode
I've tried the following code but I get this error( DbExpressionBinding requires an input expression with a collection ResultType.
Parameter name: input) :
var lstCMRInvHdrNips = (from r in e.CMR_INVHDR
where r.ProcessedLike != "STMNT ONLY"
select new {
r.IssuerCode,
r.SecurityCode,
CountofIssuerCode = r.IssuerCode.Count(),
r.DataProcessingFlag
}
).GroupBy(x =>
new {
x.IssuerCode,
x.SecurityCode,
x.DataProcessingFlag,
x.CountofIssuerCode
}
).OrderBy(x => x.Key.IssuerCode).ToList();

Is there any sense to count issuercode while grouping by this field at once? As when groupped by a field, it's COUNT will always be 1.
Probably you should not group by issuercode and count it after the GroupBy in a separate Select statement:
var result = e.CMR_INVHDR
.Where(r => r.ProcessedLike != "STMNT ONLY")
.GroupBy(r => new { r.SecurityCode, r.DataProcessingFlag })
.Select(r => new
{
Value = r.Key,
IssuerCodesCount = r.GroupBy(g => g.IssuerCode).Count()
})
.ToList();
