mysql - ungroup table, manipulate columns and convert to a row -


I have an Excel table of this structure (can be converted to XML or CSV): 

  | License plate Parking | Fuel | Cleaning | --------------------------------------------- | 1111 AAA | 234 | 21 | 1244 | | 2222 AAA 22 | 12 | 644 | | 3333 BBB | 523 | 123 | 123 |

For parking, fuel, etc. per car / month per month is spent.

There is a unique price in the license plate table.

I need to convert this table into MySQL to be imported into this table, but I do not know how to do this and which device is good for it: 

  | License plate Concept | Zodiac ------------------------------------- | 1111 AAA | Parking | 234 | | 1111 AAA | Fuel | 21 | | 1111 AAA | Cleaning | 1244 | | 2222 AAA Parking | 22 | | 2222 AAA Fuel | 12 | | 2222 AAA Cleaning | 644 | | ....... | ........ | ..... |

License plate is not a unique value in the results table, and it is repeated for the number of those concepts.

UPD: Just discovered that it might be (probably not at all) called denromalized data.

I will do this with MySQL in the following way:

Table (After converting into CSV) import into MySQL it is called 

  Table Source (License_Plate four (7) primary key, parking Integer (8) unsigned, create fuel integer (8) unsigned, cleanup (8) unsigned); Load data INFILE ',' in the All Source field defined by 'path / per / file'.

Create another table with the desired final structure, let's call it destination 

  Destination (licensed four (7), concept varchar (10), zodiac int (8) unsigned);

Display the following queries 

  include the source from the included source in the destination License_Plate, the form of 'parking' concept In License_Plate, the 'fuel' concept in the parking destination, the source from the source insert in the destination as the source of the fuel, as the source from the selection source, license_Plate, as a 'cleanup' concept, select cleaning

Things to consider:

  1. I have a primary key Has declared License_Plate in the form, just depending on your example. This can not be the case if it repeats in the actual data. Also, if you have more than one line on the source table for the same license plate, then you may need to adjust my 3 questions for the total values.
  2. In addition, datatype sampling data is adjusted, for example, if you have more than 8 digits, then it may need to be changed.
  3. One way in which you can upload your CSV, there are several options in it, you should check them, you can do it with some tools, so that you do not have to write that statement.
  4. Last, those table names were selected as an example, you should come up with better people, who represent your problem domain. / Li>

Hope this helps you.

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
