EF Core 2.0.1 - Entity framework migration specific update - minus out initial database update
Wow, this title is pretty long.
Let's say you already have an existing database and right now you wanted to use EF Core to help migrate specific DML updates to your target database - which could be creating a new View or creating additional table minus out the initial database structure.
Note : Sometimes when you do an upgrade, you might get error message saying "your database has already been updated".
All rite, to be honest, you ca't do specific migration, example you can say "apply ABC Migration".
It is all based on the migration class that you've setup in your project, meaning you get to type "Update-Database" without any parameter.
Anyways, please setup your project and all in the required EF nugets.
Next create the following class.
Then you specific what needs to be done. In this case, we are creating a view called "AppTesrtView".
Goto "package manager console" and then run "Update-Database". Please note you need to give a name to [Migration("MyMigrationName")] as shown above. Otherwise you will get an exceptions.
You cannot use " Add-Migration " because it generates the initial database structure which can be complicated to resolve.
