I've got two different list of two different objects. Then i got one list of a viewmodel that contains properties from both the objects and i want them to be joined into that list.
//Product
public string id { get; set; }
public string unitMeasurement { get; set; }
public Nullable<int> minOrderQty { get; set; }
public Nullable<int> packSize { get; set; }
public string leadTime { get; set; }
public Nullable<int> generalAccessoryCategoryId { get; set; }
public string Company { get; set; }
public Nullable<decimal> Weight { get; set; }
public Nullable<int> ProductType { get; set; }
//ProductDescription
public string id { get; set; }
public string language { get; set; }
public string shortDescription { get; set; }
public string detailDescription { get; set; }
public string Name { get; set; }
public Nullable<int> Rank { get; set; }
public Nullable<System.DateTime> StartDate { get; set; }
public Nullable<System.DateTime> EndDate { get; set; }
public class ProductResponse
{
public string id { get; set; }
//Product
public string unitMeasurement { get; set; }
public Nullable<int> minOrderQty { get; set; }
public Nullable<int> packSize { get; set; }
public string leadTime { get; set; }
public Nullable<int> generalAccessoryCategoryId { get; set; }
public string Company { get; set; }
public Nullable<decimal> Weight { get; set; }
public Nullable<int> ProductType { get; set; }
//ProductDescription
public string language { get; set; }
public string shortDescription { get; set; }
public string detailDescription { get; set; }
public string Name { get; set; }
public Nullable<int> Rank { get; set; }
public Nullable<System.DateTime> StartDate { get; set; }
public Nullable<System.DateTime> EndDate { get; set; }
}
So i just want to join a list of products and a list of productdescriptions into a list of productResponse. How can i do this? id of product and productdescription is the same so thats what i want to join them on.
Join them on id and then call ToList:
var productResponses = from p in products
join pd in productDescriptions
on p.id equals pd.id
select new ProductResponse
{
id = p.id,
language = pd.language,
// ...
}
var list = productResponses.ToList();

I want to create a query that will return an AgencyContractData object containing a DocumentDto object, but it may be that the original object does not contain a foreign key on the Document. I can't use ternary operator in an Entity-Framwork LINQ query. How it is possible to implement it (Required that select be converted to sql query)?
var contractList = await query
.Select(contract => new AgencyContractData
{
ContractId = contract.Id,
ContractNumber = contract.ContractNumber,

},
DocumentName = contract.DocumentName,
ContractNumberInt = contract.ContractNumberInt,
ContractNumberString = contract.ContractNumberString,
MsaBaseNumber = contract.MsaBaseNumber,
NotificationDays = contract.NotificationInDays,
State = contract.State,
CreatedOn = contract.CreatedOn,
CreatedBy = contract.CreatedBy,
ModifiedOn = contract.ModifiedOn,
ModifiedBy = contract.ModifiedBy,
It is the AgencyContract entity:

Ok I am kinda stuck I need a ef query that will get me the following data.
I have sessions which are created at the Gym I am using ef core here so
In the main grid I need to list the students that our their for the workout that day.

Team Includes the students and is linked back to the Student via Team Id
ID

Test Team

For Example what I want to be able to do is Pick the session that is on the start date of the 5 and display only the students attending that day.
My Poco Class for Session
public class Session
{
public int Id { get; set; }
public string? Name { get; set; }

public bool? IsDeleted { get; set; }
public int? SessionId { get; set; }
public bool? IsActive { get; set; }
public string? CreatedBy { get; set; }
public string? LastModifiedBy { get; set; }
public DateTime? LastUpdatedDate { get; set; }
public DateTime? CreatedDate { get; set; }
}
I think I need to have some link back from the Student to the session but because they can block book sessions and team level I dont no how to achieve this.
It looks like a Session has a Team(s?) and a Team has a Student(s), so it's reasonably straight forward:
context.Sessions.Include(s => s.Team).ThenInclude(t => t.Students)
.Where(s => s.StartDate == new DateTime(2021, 11, 5))
This gets you a collections of sessions that should have their Team property populated with a Team, and in turn that Team has a Students collection that is populated with Students
I have the following SQL query that I need to rewrite to Entity Framework with navigation properties. Basically, and Employee has a number of tasks that someone can volunteer to do. I'm trying to find all employees that have at least one volunteer assigned to any task.
SELECT j.noTasks, e.*
FROM Employee e
LEFT JOIN
(SELECT e.id, COUNT(vt.TaskId) as "noTasks"
FROM Employee e
LEFT JOIN Task t on e.id = t.EmployeeId
LEFT JOIN VolunteerTask vt on vt.TaskId = t.id
GROUP BY e.id) j
ON e.id = j.id AND noTasks > 0
The troubling part is the inner SELECT. I've read the documentation, but I'm having difficulties understanding it.

I am using Dapper.Net to get data from SQL Server database.
Here is my POCO classes
public partial class Production
{
public System.Guid ProductionId { get; set; }
public System.Guid SurveyId { get; set; }
public Nullable<int> PercentComplete { get; set; }
public string CompletedBy { get; set; }
public string DeliverTo { get; set; }
public virtual SurveyJob SurveyJob { get; set; }
}
public partial class SurveyJob
{
public SurveyJob()
{
this.Productions = new HashSet<Production>();
}
public System.Guid SurveyId { get; set; }
public string JobTitle { get; set; }
public Nullable<int> Status { get; set; }
public Nullable<int> JobNumber { get; set; }
public Nullable<System.DateTime> SurveyDate { get; set; }
public Nullable<System.DateTime> RequiredBy { get; set; }
public virtual ICollection<Production> Productions { get; set; }
}
I want to get all productions along with their SurveyJob information. Here is my SQL query in the stored procedure which returns these columns
SELECT
P.ProductionId, S.SurveyId,
P.PercentComplete, P.CompletedBy, P.DeliverTo,
S.JobTitle, S.JobNumber, S.RequiredBy, S.Status, S.SurveyDate
FROM
dbo.Production P WITH(NOLOCK)
INNER JOIN
dbo.SurveyJob S WITH(NOLOCK) ON S.SurveyId = P.SurveyId
Problem is that I am getting Production data but SurveyJob object is null.
Here is my c# code
var result = await Connection.QueryAsync<Production>("[dbo].[GetAllProductions]", p, commandType: CommandType.StoredProcedure);
I am getting SurveyJob object null as shown in image.
Need help. What I am doing wrong?
Your model is malformed for the query you executed, your query will return a plain object (dapper will always return plain objects), so you need a class with all the properties you're selecting.
Change your model to this:
public partial class ProductionSurvey
{
public System.Guid ProductionId { get; set; }
public System.Guid SurveyId { get; set; }
public Nullable<int> PercentComplete { get; set; }
public string CompletedBy { get; set; }
public string DeliverTo { get; set; }
public System.Guid SurveyId { get; set; }
public string JobTitle { get; set; }
public Nullable<int> Status { get; set; }
public Nullable<int> JobNumber { get; set; }
public Nullable<System.DateTime> SurveyDate { get; set; }
public Nullable<System.DateTime> RequiredBy { get; set; }
}
I have 2 models:

public int MovieGenre { get; set; }
public string MoviePicture { get; set; }
public string MovieDescription { get; set; }
public string MovieShortText { get; set; }

public virtual ICollection<TimeTable> TimeTables { get; set; }
}
And:
public partial class TimeTable

}
public int TimeTableId { get; set; }
public int MovieId { get; set; }
public int RoomId { get; set; }

public DateTime EndTime { get; set; }
public virtual Movie Movie { get; set; }
public virtual ICollection<Reservation> Reservations { get; set; }
public virtual Room Room { get; set; }
}
I want to show all the records from Movie which have one or more records in TimeTable and where StartDate.date == [given datetime].
With a simple query the movies are showing multiple times. I have tried a distinct() but that changes nothing.
Anybody here who have the solution?
Current query:
var times2 =
(from s in timetablerepo.TimeTables
orderby s.StartTime.TimeOfDay
where s.StartTime.Date == datetime.Date
select s).Distinct().ToList();
Why not start with movies first and filter by timetable:
var times = timetablerepo.Movies
.Where(m => m.TimeTables.Any(t => t.StartDate.Date == <yourdate>));
