I am still having real performance issue in a list there our 38 thousand entrys and I need to map them to another table for export I am thinking of moving it to stored proc but still worried what performance would be like there. The code works but takes a very long time to execute and wish to turn it into a stored proc.
private List<TradeItemsExport> MapTradeItems(List<TradeItems> tradeItem)
{
List<TradeItemsExport> retList = new List<TradeItemsExport>();

My problem that this takes around 30 mins to compute the results which is very slow.
This is the sql that I am doing which is a view that is the tradeitem that I am passing.
SELECT
dbo.PLSupplierAccount.SupplierAccountNumber, dbo.PLSupplierAccount.PLSupplierAccountID, dbo.PLSupplierAccount.SupplierAccountName,
dbo.PLSupplierAccount.SYSCurrencyID, dbo.PLSupplierAccount.MainTelephoneAreaCode, dbo.PLSupplierAccount.MainTelephoneCountryCode,
dbo.PLSupplierAccount.MainTelephoneSubscriberNumber, dbo.PLSupplierAccount.MainFaxCountryCode, dbo.PLSupplierAccount.MainFaxSubscriberNumber,
dbo.PLSupplierAccount.MainFaxAreaCode, dbo.PLSupplierContact.ContactName, dbo.PLSupplierContact.Description, dbo.PLSupplierContact.FirstName,
dbo.PLSupplierContact.MiddleName, dbo.PLSupplierContact.LastName, loc.AddressLine1, loc.AddressLine2, loc.AddressLine3, loc.AddressLine4, loc.PostCode,
loc.City, loc.County,
CAST(CASE WHEN loc.Country = 'Ireland' THEN 'IRL'
WHEN loc.Country = 'Great Britain'
THEN 'GBR'
ELSE 'ERR'
END AS nvarchar(3)) AS Country,
dbo.SYSCurrency.SYSCurrencyISOCodeID, dbo.SYSCurrency.SYSExchangeRateTypeID, dbo.SYSCurrency.Name AS CurrencyDescription,
dbo.SYSCurrency.Symbol AS CurrencySymbol
FROM
dbo.PLSupplierAccount
INNER JOIN
dbo.PLSupplierContact ON dbo.PLSupplierAccount.PLSupplierAccountID = dbo.PLSupplierContact.PLSupplierAccountID
INNER JOIN
dbo.PLSupplierLocation AS loc ON dbo.PLSupplierAccount.PLSupplierAccountID = loc.PLSupplierAccountID
AND dbo.PLSupplierContact.PLSupplierLocationID = loc.PLSupplierLocationID
INNER JOIN
dbo.SYSCurrency ON dbo.PLSupplierAccount.SYSCurrencyID = dbo.SYSCurrency.SYSCurrencyID
My quesiton is how would I change the above to include a sub query that would do the same as this function is doing above.
The query for the codes look up which is again another view is below.
SELECT
dbo.StockItem.ItemID, dbo.StockItem.Code, dbo.StockItem.Name, dbo.StockItemSearchCatVal.SearchValueID, dbo.SearchValue.Name AS Expr1,
dbo.SearchCategory.Name AS Expr2
FROM
dbo.SearchCategory
INNER JOIN
dbo.SearchValue ON dbo.SearchCategory.SearchCategoryID = dbo.SearchValue.SearchCategoryID
INNER JOIN
dbo.StockItemSearchCatVal ON dbo.SearchCategory.SearchCategoryID = dbo.StockItemSearchCatVal.SearchCategoryID
AND dbo.SearchValue.SearchValueID = dbo.StockItemSearchCatVal.SearchValueID
INNER JOIN
dbo.StockItem ON dbo.StockItemSearchCatVal.ItemID = dbo.StockItem.ItemID
I just feel I would get more benefit changing this into a subquery so that I am just returning the results to .net I am using the filehelpers library to output the results set of MapTradeItems to csv so obv more things I can do the better on the server.
Obv I would need some kind of temporary table to loop through the results but how quick would that be in sql server compared to a .net for each loop.
This is the poco class which I have to reproduce to csv.

I have an MVC that takes values from a form, sends them to a dll, to have logic performed on them & assigned to a model. The model is then returned to the view. In localhost it is successful and I get the following result:
However when I publish the webapp to an azure instance, it doesn't return any of the values. You can see it here: http://levelupsite.azurewebsites.net/ or see the image here
Does anyone know what could cause this? I will attach the code below:
Controller:
[HttpPost]
public ActionResult CBC(System.Web.Mvc.FormCollection form, FFAC model)
{
//recieve values from form
var email = escapeCharactersspace((form["email"].ToString()));
var Gender = Convert.ToString(model.UserGender);
var UserID = escapeCharactersspace((form["username"].ToString()));
var Neutrophils = escapeCharactersspace(form["Neutrophils"]);
var Lymphocytes = escapeCharactersspace(form["Lympthocytes"]);
var Monocytes = escapeCharactersspace(form["Monocytes"]);
var Eosinophils = escapeCharactersspace(form["Eosinophils"]);
var Basophils = escapeCharactersspace(form["Basophils"]);
var Platelets = (escapeCharactersspace(form["Platelets"]));
var Haematocrit = escapeCharactersspace(form["Haematocrit"]);
var Haemoglobin = escapeCharactersspace(form["Haemoglobin"]);
var MCV = escapeCharactersspace(form["MCV"]);
var MCH = (escapeCharactersspace(form["MCH"]));
var MCHC = escapeCharactersspace(form["MCHC"]);
//turn form to array
decimal[] cbcInputs = { Convert.ToDecimal(Neutrophils), Convert.ToDecimal(Lymphocytes), Convert.ToDecimal(Monocytes), Convert.ToDecimal(Eosinophils), Convert.ToDecimal(Basophils), Convert.ToDecimal(Platelets), Convert.ToDecimal(Haematocrit), Convert.ToDecimal(Haemoglobin), Convert.ToDecimal(MCV), Convert.ToDecimal(MCH), Convert.ToDecimal(MCHC) };
//create instance of model
var scfiae = new FIAECBC();
//create instance of external class library
var fiae = new FIAEngine();
//send inputs & model instance to external class library to perform logic
fiae.setcbcvals(cbcInputs, UserID, Gender, scfiae);
//return the get results page
return View("GetResults", scfiae);

Hi I'm a new to elastic nest API and I'm using nest 5.x. I'm currently developing some kind of advanced search page so when user doesn't check a criteria i don't have to include that filter on my query. I'm trying to combine 2 queries under must operator with object initializer approach using nest. How to achieve it? I'm following the example on [https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/bool-queries.html]
var secondSearchResponse = client.Search(new
SearchRequest {
Query = new TermQuery { Field = Field(p => p.Name), Value = "x" } &&
new TermQuery { Field = Field(p => p.Name), Value = "y" } });
But it doesnt work cause Field class doesnt accept type arguments.
I also tried to followed this approach from this topic

But that returns zero result. How to achieve this? Thx anyway.
EDIT :
This is the params variabel definition. Its apoco model of search keywords
public class SearchModels

public string emitentype { get; set; }
public string kodeemiten { get; set; }
public string issuercode { get; set; }
public int indexfrom { get; set; }
public int pagesize { get; set; }
}
IDXNetAnnouncement is a poco model of search result. Its actualy a document type which is stored on the elastic server
public class IDXNetAnnouncement
{
public string perihalpengumuman { get; set; }
public string attachments { get; set; }
public string createddate { get; set; }
public bool efekemiten_spei { get; set; }

}
But it doesnt work cause Field class doesnt accept type arguments.
You need to ensure that you include a using static directive for Nest.Infer i.e.
using static Nest.Infer;
with the rest of the using directives.
.Query(q => q.Bool(qb => qb.Must(m => m.MatchAll() && andQuery))));
No need to wrap in a Must(), just do
.Query(q => q.MatchAll() && andQuery)
which will wrap both queries in a bool query must clause. You also don't need to null check andQuery because NEST is smart enough to not combine the two queries if either or both are null.
if (!string.IsNullOrEmpty(queries.queryfields))
{
var val = queries.queryfields;
TermQuery tq = new TermQuery
{
Field = queries.queryfields,
Value = val
};
if (andQuery == null)
andQuery = tq;
else
andQuery &= tq;
//QueryContainers.Add(tq);
}
NEST has the concept of conditionless queries so you don't need to check it queries.queryfields is null or empty, simply build the query and add it to andQuery. So it would become
var val = queries.queryfields;
andQuery &= new TermQuery
{
Field = queries.queryfields,
Value = val
};
Aside
All of the NEST documentation is generated from source code; you can trace back to the original source file by clicking on any edit link within the documentation. This will take you to a github page, such as this one for bool queries. From here, the document contains an important note that links back to the original source.
I am trying to determine the Distinct count for a particular field in a collection of objects.

});
return CreateSummaryListModel(result);
}

ActualOuput for UniqueFileCount Field:
UniqueFileCount = 1
ExpectedOutput results for UniqueFileCount Field:
UniqueFileCount = 2
What am I doing wrong?
It sounds like you want the distinct count of FileId for the entire collection and not just for each group, which will always be 1 since FileId is one of the fields you group on. If that is the case then you can just calculate that count first
int distinctFileIds = remittanceCenterSummaryListModel.RemittanceBatchSummaryRecor‌​d
.Select(x => x.FileId)
.Distinct()
.Count();
Then use that in your Linq query
UniqueFileCount = distinctFileIds
I'm trying to make a progress bar for my SQL query but don't know where to start. I have tried implementing the backgroundworker but I can't seem to get it to work.
I'm using VS 2010 .NET 4.0
Treinen trein = listboxVoertuigNr.SelectedItem as Treinen;
List<string> treinenIds = new List<string>();
foreach (var item in listboxVoertuigNr.SelectedItems)

Category = cat.Cat_MMAP
});
GetGraad(FoutenResultaat);
In GetGraad() the read data from the SQL database gets placed in a list. This is a custom list because it also gets populated with values from a excel file.
private void GetGraad(IEnumerable<dynamic> mijnResultaten)

foreach (dynamic item in mijnResultaten)

string compare = modNaam[0].Substring(0, modNaam[0].Length - 1).ToString();
if (compare == "MPU")
{
var index = Properties.Settings.Default.listFoutcodeMPU.FindIndex(a => a == item.FoutCode);
if (index == -1)
graad = "";
else
{
graad = Properties.Settings.Default.listGraadMPU[index];
Toolbox = Properties.Settings.Default.listToolboxMPU[index];
}
}
if (compare == "AAUX")
{
var index = Properties.Settings.Default.listFoutcodeAAUX.FindIndex(a => a == item.FoutCode);
if (index == -1)
graad = "";
else
{
Toolbox = Properties.Settings.Default.listToolboxAAUX[index];
graad = Properties.Settings.Default.listGraadAAUX[index];
}
}
if (compare == "CTRL")
{
var index = Properties.Settings.Default.listFoutcodeCTRL.FindIndex(a => a == item.FoutCode);
if (index == -1)
graad = "";
else
{
Toolbox = Properties.Settings.Default.listToolboxACTRL[index];
graad = Properties.Settings.Default.listGraadCTRL[index];
}
}
string cat = Convert.ToString(item.Category);
if (cat == null)
cat = "Onbeschikbaar";
try
{
dataTreinFouten.Add(new FoutenMetNaam { Datum = item.Datum, FoutCode = item.FoutCode, Module = modNaam[0].ToUpper(), File = modNaam[1].ToUpper(), Name = item.Name, Omschrijving = item.Omschrijving, Time = item.Time, Graad = graad, FoutId = item.FoutId, Toolbox = Toolbox, Category = cat.ToUpper()});
}
catch (Exception ex)
{
Xceed.Wpf.Toolkit.MessageBox.Show(ex.Message);
}
}
}
The list is used to populate a datagrid, the class used for the list "dataTreinFouten":
class FoutenMetNaam
{
public DateTime Datum { get; set; }
public TimeSpan Time { get; set; }
public String FoutCode { get; set; }
public String Omschrijving { get; set; }

public List<ExtraInfo> listInfoRondFout { get; set; }
public bool isManueel { get; set; }
public string Toolbox { get; set; }
public string Category { get; set; }
}
But I can't really get the state of how far the query is already. Which means I can't update a progress bar with it current state and because the database can contain over 30.000.000 results it is quite needed.
EDIT:
I added a Entity Data Model generated from my SQL database "Events".
Code to use this:
private EventsEntities eventsEntities = new EventsEntities();
Any help or pointing in the right direction is greatly appreciated!
I want to group the below query by GetSetDomainName and select the row which has the maximum GetSetKalanGun.In other words, I am trying to get the row with the maximum KALANGUN among those which have the same DOMAINNAME.
var kayitlar3 = (
from rows in islemDetayKayitListesi
select new
{
KAYITNO = rows.GetSetKayitNo,
HESAPADI = rows.GetSetHesapAdi,
URUNNO = rows.GetSetUrunNo,
URUNADI = rows.GetSetUrunAdi,
URUNMIKTAR = rows.GetSetUrunMiktar,
ISLEMTARIHI = rows.GetSetIslemTarihi,
HIZMETDURUMU = rows.GetSetHizmetDurumu,
TOPLAMTUTAR = rows.GetSetToplamTutar,
HIZMETBASLANGICTARIHI = rows.GetSetHizmetBaslangicTarihi,
HIZMETBITISTARIHI = rows.GetSetHizmetBitisTarihi,
KALANGUN = rows.GetSetKalanGun
DOMAINNAME = rows.GetSetDomainName,
SIPARISDURUMU = rows.GetSetSiparisDurumu
}).AsQueryable();
This is what I get
KAYITNO DOMAINNAME KALANGUN
1 asdf.com 30
2 domnam.com 172
3 asdf.com 40
4 xyz.com 350
This is what I want
KAYITNO DOMAINNAME KALANGUN
2 domnam.com 172
3 asdf.com 40
4 xyz.com 350
var islemDetayKayitListesi = new List<IslemDetayKayit>();
islemDetayKayitListesi get filled with a foreach loop, with no problem
And that is what IslemDetayKayit looks like
public class IslemDetayKayit
{
public int GetSetKayitNo { get; set; }
public string GetSetHesapAdi { get; set; }
public string GetSetUrunNo { get; set; }
public string GetSetUrunAdi { get; set; }
public double GetSetUrunMiktar { get; set; }
public string GetSetIslemTarihi { get; set; }
public string GetSetHizmetDurumu { get; set; }
public string GetSetToplamTutar { get; set; }
public string GetSetHizmetBaslangicTarihi { get; set; }
public string GetSetHizmetBitisTarihi { get; set; }
public int GetSetKalanGun { get; set; }
public string GetSetSiparisDurumu { get; set; }
public string GetSetDomainName { get; set; }
}
EDIT : I figured out that there was some other problem in my code, and corrected it.After that all the answer I had to this question works.Thank you for helping and teaching me new things.
This will do the trick:
var q =
from item in kayitlar3
group item by item.DOMAINNAME into g
select g.OrderByDescending(i => i.KALANGUN).First();
You can also try this:
var q =
from row in islemDetayKayitListesi
group row by row.GetSetDomainName into g
let highest = g.OrderByDescending(r => r.GetSetKalanGun).First()
select new
{
KAYITNO = highest.GetSetKayitNo,
DOMAINNAME = g.Key,
KALANGUN = highest.GetSetKalanGun
};
Note that this would yield the same results. If it doesn't, there is a problem with your code that we can't see by looking at the information that you posted.
You could use:
var kayitlar3 =
islemDetayKayitListesi.
Select(rows =>
new
{
KAYITNO = rows.GetSetKayitNo,
HESAPADI = rows.GetSetHesapAdi,
URUNNO = rows.GetSetUrunNo,
URUNADI = rows.GetSetUrunAdi,
URUNMIKTAR = rows.GetSetUrunMiktar,
ISLEMTARIHI = rows.GetSetIslemTarihi,
HIZMETDURUMU = rows.GetSetHizmetDurumu,
TOPLAMTUTAR = rows.GetSetToplamTutar,
HIZMETBASLANGICTARIHI = rows.GetSetHizmetBaslangicTarihi,
HIZMETBITISTARIHI = rows.GetSetHizmetBitisTarihi,
KALANGUN = rows.GetSetKalanGun,
DOMAINNAME = rows.GetSetDomainName,
SIPARISDURUMU = rows.GetSetSiparisDurumu
}).
GroupBy(a =>
//To ignore case and trailing/leading whitespace
a.DOMAINNAME.ToUpper().Trim()).
Select(g =>
g.OrderByDescending(a => a.KALANGUN).FirstOrDefault()).
AsQueryable();
EDIT:
So using this code:
List<Thing> islemDetayKayitListesi = new List<Thing>();
Thing a = new Thing() { GetSetDomainName = "abc.com", GetSetKayitNo = 1,
GetSetKalanGun = 40 };
Thing b = new Thing() { GetSetDomainName = "abc.com", GetSetKayitNo = 2,
GetSetKalanGun = 300 };
Thing c = new Thing() { GetSetDomainName = "xyz.com", GetSetKayitNo = 3,
GetSetKalanGun = 400 };
Thing d = new Thing() { GetSetDomainName = "123.com", GetSetKayitNo = 4,
GetSetKalanGun = 124 };
islemDetayKayitListesi.Add(a);
islemDetayKayitListesi.Add(b);
islemDetayKayitListesi.Add(c);
islemDetayKayitListesi.Add(d);
var kayitlar3 =
islemDetayKayitListesi.
Select(rows =>
new
{
KAYITNO = rows.GetSetKayitNo,
HESAPADI = rows.GetSetHesapAdi,
URUNNO = rows.GetSetUrunNo,
URUNADI = rows.GetSetUrunAdi,
URUNMIKTAR = rows.GetSetUrunMiktar,
ISLEMTARIHI = rows.GetSetIslemTarihi,
HIZMETDURUMU = rows.GetSetHizmetDurumu,
TOPLAMTUTAR = rows.GetSetToplamTutar,
HIZMETBASLANGICTARIHI = rows.GetSetHizmetBaslangicTarihi,
HIZMETBITISTARIHI = rows.GetSetHizmetBitisTarihi,
KALANGUN = rows.GetSetKalanGun,
DOMAINNAME = rows.GetSetDomainName,
SIPARISDURUMU = rows.GetSetSiparisDurumu
}).
GroupBy(anon =>
anon.DOMAINNAME).
Select(g =>
g.OrderByDescending(anon => anon.KALANGUN).First()).
AsQueryable();
kayitlar3.ToList().
ForEach(anon => Console.WriteLine("{0}, {1}, {2}",
anon.KAYITNO, anon.DOMAINNAME, anon.KALANGUN));
struct Thing
{
public int GetSetKayitNo { get; set; }
public int GetSetHesapAdi { get; set; }
public int GetSetUrunNo { get; set; }
public int GetSetUrunAdi { get; set; }
public int GetSetUrunMiktar { get; set; }
public int GetSetIslemTarihi { get; set; }
public int GetSetHizmetDurumu { get; set; }
public int GetSetToplamTutar { get; set; }
public int GetSetHizmetBaslangicTarihi { get; set; }
public int GetSetHizmetBitisTarihi { get; set; }
public int GetSetKalanGun { get; set; }
public string GetSetDomainName { get; set; }
public int GetSetSiparisDurumu { get; set; }
}
I get the expected output:
2, abc.com, 300
3, xyz.com, 400
4, 123.com, 124
After clarification about your desired output, this will return the row with the top KALANGUN per DOMAINNAME:
var kayitlar3 = (
from rows in islemDetayKayitListesi
select new
{
KAYITNO = rows.GetSetKayitNo,
HESAPADI = rows.GetSetHesapAdi,
URUNNO = rows.GetSetUrunNo,
URUNADI = rows.GetSetUrunAdi,
URUNMIKTAR = rows.GetSetUrunMiktar,
ISLEMTARIHI = rows.GetSetIslemTarihi,
HIZMETDURUMU = rows.GetSetHizmetDurumu,
TOPLAMTUTAR = rows.GetSetToplamTutar,
HIZMETBASLANGICTARIHI = rows.GetSetHizmetBaslangicTarihi,
HIZMETBITISTARIHI = rows.GetSetHizmetBitisTarihi,
KALANGUN = rows.GetSetKalanGun
DOMAINNAME = rows.GetSetDomainName,
SIPARISDURUMU = rows.GetSetSiparisDurumu
})
.GroupBy(rr => rr.DOMAINNAME)
.SelectMany(gg => gg.OrderByDescending(rr => rr.KALANGUN).First());
Try
from rows in islemDetayKayitListesi
group rows by new { rows.GetSetDomainName} into results
let MaxKALANGUN = results.Max(i=>i.KALANGUN)
select new
{
KAYITNO = results.First(i=>i.KALANGUN== MaxKALANGUN).GetSetKayitNo
DOMAINNAME = results.Key.GetSetDomainName ,
KALANGUN = MaxKALANGUN
}
If you want the complete class, try
from rows in islemDetayKayitListesi
group rows by new { rows.GetSetDomainName} into results
let MaxKALANGUN = results.Max(i=>i.KALANGUN)
select results.First(i=>i.KALANGUN== MaxKALANGUN)
