I've below SQL query
Select LC.*,LP.[LandingPageName] from [LandingPageCompanies] LC
Left join [LandingPageContent] LP on LP.SubCategoryID=LC.SubCategoryID
where LC.[CategoryID]=17
And i need to convert it into LINQ to entity.
i've tried the following query, But it's working as Inner join
var data = (from t1 in dbSavingContainer.LandingPageCompanies
join t2 in dbSavingContainer.LandingPageContents on t1.SubCategoryID equals t2.SubCategoryID
where t1.CategoryID == CategoryID
select new
{
CategoryID = t1.CategoryID,
CompanyID = t1.CompanyID,
CompanyLink = t1.CompanyLink,
CompanyLogo = t1.CompanyLogo,
CompanyName = t1.CompanyName,
SubCategoryID = t1.SubCategoryID,
LandingPageName = t2.LandingPageName
}).ToList();
Where i'm lacking. ?
Thanks..i just solved it using below query ;)
var data = (from t1 in dbSavingContainer.LandingPageCompanies
join t2 in dbSavingContainer.LandingPageContents on t1.SubCategoryID equals t2.SubCategoryID
into x from y in x.DefaultIfEmpty()
where t1.CategoryID == CategoryID
select new
{
CategoryID = t1.CategoryID,
CompanyID = t1.CompanyID,
CompanyLink = t1.CompanyLink,
CompanyLogo = t1.CompanyLogo,
CompanyName = t1.CompanyName,
SubCategoryID = t1.SubCategoryID,
LandingPageName = y.LandingPageName
}).ToList();

I have a query and want to COUNT all the related ids from other table.
I am using CTE and I also assigning variables.
When I print I get all the ids but how can I COUNT the same ids? I mean if I have an id "254aswer" 3 times it should show 3
This is the query:

SET #ITEM = (Select COUNT(*) from QuoteLineItem where Id = #ID)
PRINT #ITEM
I tried to create a new select like this:
SET #ITEM = (Select COUNT(*) from QuoteLineItem where Id = #ID)
But it only count all the items and I need to show the count for each of the ids. How can I get that?
I fixed it with this:
select count(QuoteId) from QuoteLineItem Where QuoteId = q.Id Group by QuoteId

How do i make that query in linq please advise
select *
from tblPermission
where RoleId in (select roleid from tbluserrole where userid = #userID)
When converting from SQL to LINQ, convert in the order of the LINQ phrases. If your SQL has table aliases, use them as the range variables. If a query contains a sub-query, translate it first in the same way. Translate IN into Contains.
var roles = from ur in tbluserrole where ur.userid == parmUserId select ur.RoleId;
var ans = from p in tblPermission
where roles.Contains(p.RoleId)
select p;
You can do this in 2 ways:
var roles = tbluserrole.Where(e => e.userid == userId).Select(e => e.roleid).ToList();
var prmsns = tblPermission.Where(e => roles.Contains(e.RoleId).ToList()
or
var prmsns = (from e in tblPermission
let roles = tbluserrole.Where(f => f.userid == userId).Select(f =>
f.roleid).ToList();
where roles.Contains(e.RoleId)
select e).ToList();
from
EDIT:
you can do this with inner join like this
var prmsns = (from e in tblPermission
join f in tbluserrole on tblPermission.RoleId equals tbluserrole.roleid
where f.userId == userId
select e).ToList();
I have created an SQL query as follows:
SELECT s.FullName, s.[Id], COUNT(t.[User]) AS Records
FROM dbo.AspNetUsers s INNER JOIN dbo.PBBuilds t
ON s.Id = t.[User]
GROUP BY t.[User], s.[FullName], s.[Id]
ORDER BY COUNT(t.[User]) DESC
I'm attempting to convert this to a LINQ query, and this is how far i have got:
Dim results = From H In context.Users
Join C In context.PBBuilds On H.Id Equals C.User
Group By C.User Into
Could anyone please advise.
Try this query -- (make changes accordingly though)
var results = From U In context.AspNetUsers
Join P In context.PBBuilds On U.Id Equals P.User
Group By new { P.User, U.FullName } Into g
Orderby COUNT(P.User) Descending
select new {
FullName = U.FullName,
ID = U.Id,
Records = COUNT(P.User)
};
try code
var results = From U In context.AspNetUsers
Join P In context.PBBuilds On U.Id Equals P.User
Group new {U,P} By new { P.User, U.FullName } Into g
select new {
FullName = g.FirstOrDefault().U.FullName,
ID = g.FirstOrDefault().U.Id,
Records = g.Count()
}).OrderByDescending(c=>c.Records).ToList();
We have the following database structure:
How can we query for all the data that belongs to a specific client and group? (An example written using Entity Framework 6 would be great.)
We could do something like this:
var parentChild1 = dbcontext.Parent1.Include(p => p.Child1).Select(p => p.ClientId = clientId).ToList();
var parentChild2 = dbcontext.Parent2.Include(p => p.Child2).Select(p => p.GroupId = groupId).ToList();
// And the manually join the values in parentChild2 with the objects in parentChild1.
// But there has to be a better way than this.
I'm thinking something like this; but can't figure out how to wire up child1(s) with child2(s):
void GetData(int clientId, int groupId)
{
var query = (from p1 in dbcontext.Parent1
from c1 in dbcontext.Child1
where p1.ClientId == clientId && c1.Parent1Id == p1.Id
join p2 in dbcontext.Parent2.Where(p2 => p2.GroupId == groupId)
on p1.Id equals p2.Parent1Id into p2groups
join c2 in dbcontext.Child2 on c1.Id equals c2.Child2Id into c2groups
from p2g in p2groups.DefaultIfEmpty()
from c2g in c2groups.DefaultIfEmpty()
select new Parent1
{
Parent2s = p2g,
//Child1s = c2g ??? How to wire up child1s with child2s?
};
}
The following sql statement should return all the data that belongs to a single parent1Id and groupId, from all the tables.
SELECT *
FROM Parent1 p1
LEFT JOIN Parent2 p2 ON(p1.Id = p2.Parent1Id AND p2.GroupId = #groupId)
LEFT JOIN Child1 c1 ON(p1.id = c1.Parent1Id)
LEFT JOIN Child2 c2 ON(c1.id = c2.Childe1Id AND p2.id = c2.Parent2Id)
WHERE p1.Id = #Id
The child joins are left joins since I assume not all parents have children, but the parents join is an inner join since you need the groupid as well as the parent1 id.
