php - How do I execute a query with an advanced ORDER BY situation? -


I have a question about a query in MySQL which I am trying to do. Suppose i have the following table:

table: product 

  id | Name | Price | Value_mode | 0 | Product 1 | 150 | 1 | 1 | Product 2 | 5 | 2 | 2 | Product3 | 8 | 2 |

And if I want to order products by value DESC but by price_mode "2" , Then I want the value to be multiplied by a number, say 20 for example.

With this criterion, the table order should be ordered: product3, product1, product2.

I hope you understand my questions and thanks! :

You can do this with expression in order : <: > 

  command (when price_mode = 2 then price * 20 other price end) desc

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
