Hello, When retrieving records by joining two tables wherein the foreign key of the referenced table is a nullable column, and you want to return all records from the primary table, with or without the matching rows in the right table, the query would be using left join rather than inner join. So in LINQ expression, rather than inner join, revise the query to left join as presented below. Show products with matching categories, disregarding other products without categories MVC View: Code: 1 2 3 4 5 6 7 8 9 10 11 model.Products .AddRange( ( from item in context.Products .Where(item => item.Name.Trim().StartsWith(selectedLetter)) join category in context.ProductSubcategories on item.ProductSubcategoryID equals category.ProductSubcategoryID select new ProductModel() { ProductName = item.Name, ProductID = item.ProductID, ProductNumber = item.ProductNumber, Color = ( string .IsNullOrEmpty(item.Color)) ?

As I was creating a simple Create, Update, Delete (CRUD) application in ASP.NET MVC 5 and executing the controller on Edit, I encountered an error called "Store update, insert, or delete statement affected an unexpected number of rows (0)". After debugging and looking at the stack trace, I found out that the value of the primary key is zero. Department: "Education" Designation: "Dean" EmployeeName: "JE" EmployeeID: 0 Salary: 25500 The fix for this issue is to add a hidden field to the edit view referencing to the primary key which in this case is the EmployeeID. @Html.HiddenFor(model => model.EmployeeID) And now, the model passed to the context now has a value for the EmployeeID field. Department: "Education" Designation: "Dean" EmployeeName: "JE" EmployeeID: 2 Salary: 25500 Cheers! :)
