Question

I have researched on the net and most result are converting from sql to linq and seldom have linq to sql.

this is the code which I want to convert to SQL :

 using (CommerceEntities db = new CommerceEntities())
    {
    try
      {
      var query = (from ProductOrders in db.OrderDetails
                        join SelectedProducts in db.Products on ProductOrders.ProductID  
                        equals SelectedProducts.ProductID
                        group ProductOrders by new
                            {
                            ProductId = SelectedProducts.ProductID,
                            ModelName = SelectedProducts.ModelName
                            } into grp
                        select new
                            {
                            ModelName = grp.Key.ModelName,
                            ProductId = grp.Key.ProductId,
                            Quantity = grp.Sum(o => o.Quantity)
                            } into orderdgrp where orderdgrp.Quantity > 0 
                        orderby orderdgrp.Quantity descending select orderdgrp).Take(5);

                    RepeaterItemsList.DataSource = query;
                    RepeaterItemsList.DataBind(); 
      }
    catch (Exception exp)
      {
      throw new Exception("ERROR: Unable to Load Popular Items - " + 
                           exp.Message.ToString(), exp);
      }
    }

You can attempt to run the LINQ statement in LinqPad. For examples on how to use LinqPad, check the answer here.

It has a tab to show the generated SQL statement.
