c# - Refactoring code whilst using Entity Framework -

-

I have a small application that uses EF to continue my data.

Currently, I have a single 'ticket' class which goes directly to the 'ticket' table.

However, now there is a need to make different types of tickets (such as cruise tickets, airline tickets, train tickets), so I want my code to be rebroadced on the basis of these three ticket types. They are all received from the base ticket class.

Is it possible to make such refactoring while maintaining / modifying the existing database?

The feeling of my stomach is that it would be almost impossible to do this without rebooting my database again, and then copy the data from the existing database.

You will have to use tabletivity for this case EF will create one to two tables of the same < / P> 

  [table ("ticket")] class ticket {{key] long id {get; Set;}} [table ("airtalk")] class airticket: ticket {string some special report} {get; Set;}} Here

Here the table ticket will be a general list of all the columns.

Ticket Ticket = db.Ticket.Where (n = & gt; n .ID == ticketID). Before and after default (); // Ticket price will be a type of child (air or etc.)

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings.

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
