Question

I need help to convert a SQL query to entity query in my C# code.
The query combines 4 different tables together which is as follows:

SELECT a.email,
       a.status,
       a.createdat,
       b.unitprice,
       c.name,
       d.name,
       e.name 
FROM Orders a, 
     Orderdetails b, 
     ServiceOptions c, 
     services d, 
     merchants e 
WHERE a.id=b.orderid AND c.id=b.serviceoptionid
      AND c.serviceid=d.id AND d.merchantid=e.id

Answer 1

var query = from a in context.Orders
            join b in context.OrderDetails on a.id equals b.orderid
            join c in context.ServiceOptions on b.serviceoptionid equals c.id
            join d in context.services on c.serviceid equals d.id
            join e in context.merchants on d.merchantid equals e.id
            select new { a.email, 
                         a.status, 
                         a.createdat,
                         b.unitprice, 
                         c.name, 
                         d.name, 
                         e.name };
