POSorting issue with LINQ query and join using tables from different databases
text
Body
copied!<p>I'm having trouble writing my LINQ query. Here's the scenario:</p> <p>I have 2 databases: A and B In database A: I have a tableX which has the following fields: Employee ID, Name, Address, Phone, ..., Active</p> <p>In database B: I have a tableY which has the following fields: Employee ID, Visible, Order</p> <p>the number of records in table Y is less than or equal to the number of records in table X.</p> <p>Basically, I need to extract the employee records from table X who have the attribute 'Visible' (in table Y) set to True and would like to sort them using the 'Order' attribute.</p> <p>This is what I have so far:</p> <pre><code>ADataContext dbA = new ADataContext(); BDataContext dbB = new BDataContext(); //Get the list of records from tableY where 'Visbile' is set to True var List = dbB.tableY .Where(x => x.Visible == true).OrderBy(x => x.Order) .ToList(); //Extract the list of employee IDs IEnumerable<int> ids = List.Select(x => x.EmployeeID).Distinct(); var employees = dbA.tableX .Where(x => ids.Contains(x.EmployeeID) && x.Active == true) .ToList(); </code></pre> <p>I'm able to get the correct list of employees, but cannot figure out how to apply the sorting order (present in tableY) on tableX Currently, regardless of the order specified in tableY, the records returned from tableX are sorted as they were entered in the table (oldest to most recent).</p> <p>Any ideas how I can fix my query.</p> <p>Thanks,</p>
