Set up database

To create MySQL database, we must have IDE for MySQL or we need to have MySQL CLI. We can create the database, either with IDE or using CLI commands.

We can create the database in both ways. Let’s check out CLI first.

  • To create database, using CLI, we first need to login with password, which we have provided at the time of installation.
  • After login, type the command “create database MusicStoreDB;”.

  • To check if DB is created or not, run the command given below.

Add Album properties in an Album class.

  • Create a new MusicStoreContext class, which will contain the connections and MusicStore data entities, as shown below.
  • To use context in our Application, we need to register instance as a Service in our Application. To register context, we need to add on line of code in ‘startup.cs’ file under ‘ConfigureServices’ method.

Fetch data from My SQL database

  • To get the data from the database, we need ‘GetAllAlbums()’ method, our DB context, add ‘GetAll Albums()’ method in “MusicStoreCotext” class.
  • Now, we need controller to manage our code. Add controller with name AlbumsController.

Add the code given below in Album Controller to get the data from DB.

  • After adding controller and code, we need view to display the data to the end user. Create folder under Views with name Albums. Right click on Albums folder and add new view Albums.
  • Select Layout page by clicking button. Now, click add.

You can create view from by selecting data model in dropdown or you can create blank view with the default index name and add the code, as shown below.

  1. To route to our Album action, we need to update Startup.cs and add Album controller name, so we after running an app directly. We get the “Album/index” page.

  • Now, just run an Application and we will get the output, as shown below.
