combine three queries - c#

How can I combine these 3 queries together and return them as datatable:
1:
var TDD = 0;
var queryTDD = (from x in db.GetAll<WMINO>()
join y in db.GetAll<WMCTM>()
on x.PO_ID equals y.Contract_ID
select new
{
TDD = x.Payable,
});
2:
Decimal TotalToDatePayable = 0;
TotalToDatePayable = ((from ori in db.GetAll<WMPORI>()
join ctm in db.GetAll<WMCTM>()
on ori.CTMSysID equals ctm.CTMSysID
select ori.ExB4Taxes).Sum());
3:
var query = from ctm in db.GetAll<WMCTM>()
join vnm in db.GetAll<WMVNM>()
on ctm.VendSysID equals vnm.VendSysID
where ctm.WONOs == workOrder && ctm.TransType == "Purchase Order"
select new
{
ctm.CTMSysID,
ctm.Contract_ID,
ctm.VNM_ID};`
any help is appreciated


Not possible with this because each query has different result and using different columns and condition....
There is no meaning in combining this queries.............

How do you Left join 'Is Not Null' using linq?

I am having some issues getting my LINQ statement to work. I am left joining a table, secondTable, where one of the columns can be null but I only need the records where this column is not null. I'm not sure how to get the following into a LINQ expression
LEFT JOIN secondTable b ON a.ID = b.oneTableID AND b.name IS NOT NULL
So far my LINQ is:
var list = await (from one in dbRepository.oneTable
join two in dbRepository.secondTable
on new { name = one.name, phone = one.phone, height = { is not null} } equals new
{ name = two.name, phone = two.phone, height = two.height
into temp
from two in temp.DefaultIfEmpty()
select new.....
Any Ideas?
EDIT 1: I was able to find a solution.
var list = await (from one in dbRepository.oneTable
join two in dbRepository.secondTable
on new { name = one.name, phone = one.phone, height = false } equals new
{ name = two.name, phone = two.phone, height = string.IsNullOrEmpty(two.height)}
into temp
from two in temp.DefaultIfEmpty()
select new.....

You have to use SelectMany possibility to create LEFT JOIN:
var query =
from one in dbRepository.oneTable
from two in dbRepository.secondTable
.Where(two => two.name = one.name && two.phone == one.phone
&& two.height != null)
.DefaultIfEmpty()
select new.....

Try this one:
var list = await (from one in dbRepository.oneTable
join two in dbRepository.secondTable
on new { name = one.name, phone = one.phone}
equals new
{ name = two.name, phone = two.phone}
into temp
from two in temp.DefaultIfEmpty()
where one.height == null || one.height = two.height
select new.....

Converting complex SQL with FULL JOIN to Linq

I am trying to convert a SQL statement to Linq/Entity Framework, and am having a difficult time. Below is the SQL.
SELECT
trust.FName,
trust.MName,
trust.LName
tla.Address,
tma.Address,
at.Descr
FROM CLIENTSSUITS cs
INNER JOIN TRUSTS trust ON trust.SSN = cs.CLIENT
FULL JOIN ADV_TYPES at ON at.CODE = trust.AT
LEFT OUTER JOIN CLIENTADDRESSES tla ON tla.SSN = trust.SSN AND tla.ID = 'L'
LEFT OUTER JOIN CLIENTADDRESSES tma ON tma.SSN = trust.SSN AND tma.ID = 'M'
WHERE cs.PRIMARY = w AND SecondaryRole = x AND cs.ID = y AND cs.Rev = z AND cs.DELETED = 0
GROUP BY trust.FName,
trust.MName,
trust.LName,
tla.Address,
tma.Address,
at.Descr
The FULL JOIN and the GROUP BY seem to be what I'm struggling most with. I've reviewed this SO answer and I understand how to execute a FULL JOIN on its own, but can't figure out how to integrate that into the larger overall query.
TYA for any answers.

Try this
using(var ctx = new Dbcontext())
{
var list = (
from cs in ctx.CLIENTSSUITS
join trust in ctx.TRUSTS on cs.CLIENT equals trust.CLIENT
join at in ctx.ADV_TYPES on at.CODE equals trust.AT into temp from temp.DefaultIfEmpty()
join tla1 in ctx.CLIENTADDRESSES on tla.SSN equals trust.SSN && tla.ID = 'L' into temp2 from subtla1 in temp2.DefaultIfEmpty()
join tla2 in ctx.CLIENTADDRESSES on tla2.SSN equals trust.SSN && tla2.ID = 'M' into temp3 from subtla2 in temp3.DefaultIfEmpty()
where (cs.PRIMARY = w && ?.SecondaryRole = x && cs.ID = y && cs.Rev = z && cs.DELETED = 0)
select new
{
FName = trust.FName,
MName = trust.MName,
LName = trust.LName
LAddress = tla.Address,
MAddress = tma.Address,
Descr = at.Descr
}).ToList();
}
//if the list contains the right result then you can easily group it with this code
var results = list.GroupBy(x => new {
x.FName, x.MName, x.LName, x.LAddress, x.MAddress, Descr
});

LINQ: join multiple Table Column using Linq and find aggregated sum from child table values

I'm using Linq (code-first approach) query to retrieve the data from DB and couldn't able to get similar result while using below linq query:
from msi in db.MainSaleInvoiceTbls
join dsi in db.DetialSaleInvoiceTbls on msi.Id equals dsi.MainSaleInvoiceId
join ca in db.CustomerAccounts on msi.CustomerId equals ca.Id
join cg in db.MiscLists on ca.CustomerGroupId equals cg.Id
where msi.IsActive == true && msi.CompanyId == UniversalInfo.UserCompany.Id && msi.MainSaleInvoiceDataType == MainSaleInvoiceType.SOInvoice
group msi by new { dsi,msi.Date,msi.FinancialVoucher,msi.SaleOrderPrefix,msi.SaleOrderNumber,msi.SalesId,ca.CustomerName,ca.AccountCode,cg.Name }
into mainSaleInvoice
from dx in mainSaleInvoice.DefaultIfEmpty()
// orderby main.Id
select new
{
Date = mainSaleInvoice.Key.Date,
Voucher = mainSaleInvoice.Key.FinancialVoucher,
InvoiceAccount = mainSaleInvoice.Key.AccountCode,
CustomerName = mainSaleInvoice.Key.CustomerName,
CustomerGroup = mainSaleInvoice.Key.Name,
Invoice = mainSaleInvoice.Key.SaleOrderPrefix + mainSaleInvoice.Key.SaleOrderNumber,
PurchaseOrder = mainSaleInvoice.Key.SalesId,
SalesTax = "",
InvoiceAmount = mainSaleInvoice.Sum(x => (Double)(mainSaleInvoice.Key.Quantity * mainSaleInvoice.Key.UnitPrice))
}).ToList()
In linq, i need to get shortdatetimeString() and sum() of (unitprice* quantity) from child table DetialSaleInvoiceTbls
being new in query writing, I don't know where and what I'm doing wrong. Any suggestions would be much appreciated.

var list=from msi in db.MainSaleInvoiceTbls
join dsi in db.DetialSaleInvoiceTbls on msi.Id equals dsi.MainSaleInvoiceId
join ca in db.CustomerAccounts on msi.CustomerId equals ca.Id
join cg in db.MiscLists on ca.CustomerGroupId equals cg.Id into a
where msi.IsActive == true && msi.CompanyId == UniversalInfo.UserCompany.Id
&& msi.MainSaleInvoiceDataType == MainSaleInvoiceType.SOInvoice
from cg in a.DefaultIfEmpty()
select new
{mainSaleInvoice.Date,
mainSaleInvoice.FinancialVoucher,mainSaleInvoice.AccountCode,
mainSaleInvoice.CustomerName,mainSaleInvoice.Name,
mainSaleInvoice.SaleOrderPrefix, mainSaleInvoice.SaleOrderNumber,
mainSaleInvoice.SalesId, }).sum(x=>x. (mainSaleInvoice.Quantity *
mainSaleInvoice.UnitPrice)).groupby msi new
{msi.Date,msi.FinancialVoucher,msi.SaleOrderPrefix,msi.SaleOrderNumber,
msi.SalesId};
Date = mainSaleInvoice.Date;
Voucher = mainSaleInvoice.FinancialVoucher;
InvoiceAccount = mainSaleInvoice.AccountCode;
CustomerName = mainSaleInvoice.CustomerName;
CustomerGroup = mainSaleInvoice.Name;
Invoice = mainSaleInvoice.SaleOrderPrefix +
mainSaleInvoice.SaleOrderNumber;
PurchaseOrder = mainSaleInvoice.SalesId;
SalesTax = "";

Group_concat on the basis of Education Id, DoctorspecialitiesID, Avaibilities Id,
Image of Input and desire Output

Looking at you example output, it looks less like you want to "concat the data by ','" as much as you want to convert it to JSON.
Inwhichcase, you'd probably be better off using a tool like Newtonsoft's JSON.NET
UPDATE (based on comments):
Assume doctors is the result of the query given in question.
var output =
from d in doctors
group d by new { d.D_NAME, d.D_Area } into dg
select new DoctorDisplay
{
D_NAME = dg.Key.D_NAME,
D_Area = dg.Key.D_Area,
D_SpecialityName = String.Join(",", dg.Select(d => d.D_SpecialityName).Distinct()),
D_DegreeName = String.Join(",", dg.Select(d => d.D_DegreeName).Distinct())
};

linq left join with filtering in joined

I am getting duplication meals here
IEnumerable<DTOHotMealsPrice> lst = (from m in this.dbEntity.HOT_MEALS
join ml in this.dbEntity.HOT_MEALS_PRICE on m.MEALSID equals ml.MEALSID into mls
from mls1 in mls.DefaultIfEmpty()
where mls1.HOTID==hotelId
select new DTOHotMealsPrice
{
MEALSID = m.MEALSID,
MEALSNAME = m.MEALSNAME,
CHPRICE = mls1.CHPRICE,
PRICE = mls1.PRICE,
HOTID = mls1.HOTID
}).Distinct().ToList();
I want to list all HOT_MEALS and also join with
HOT_MEALS_PRICE when a mealsid reference on it
When mls1.HOTID==hotelId, this will getting innerjoin results
How could it will a proper result

Two Way solve Solution
Remove Where Case
Add where Case In Join table
Show for Where Case Blow Linq Query
first Query
IEnumerable<DTOHotMealsPrice> lst = (from m in this.dbEntity.HOT_MEALS
join ml in this.dbEntity.HOT_MEALS_PRICE.where(c=>c.HOTID==hotelId) on m.MEALSID equals ml.MEALSID into mls
from mls1 in mls.DefaultIfEmpty()
select new DTOHotMealsPrice
{
MEALSID = m.MEALSID,
MEALSNAME = m.MEALSNAME,
CHPRICE = mls1.CHPRICE,
PRICE = mls1.PRICE,
HOTID = mls1.HOTID
}).Distinct().ToList();
Second is:
IEnumerable<DTOHotMealsPrice> lst = (from m in this.dbEntity.HOT_MEALS
join ml in this.dbEntity.HOT_MEALS_PRICE on m.MEALSID equals ml.MEALSID into mls
from mls1 in mls.where(c=>c.HOTID==hotelId).DefaultIfEmpty()
select new DTOHotMealsPrice
{
MEALSID = m.MEALSID,
MEALSNAME = m.MEALSNAME,
CHPRICE = mls1.CHPRICE,
PRICE = mls1.PRICE,
HOTID = mls1.HOTID
}).Distinct().ToList();
