如何在实体框架 6 中为 SQL 查询创建迁移？

Question

I am using Entity framework 6 code 1st.

I have couple SQL queried as follows:

delete from [dbo].[User];


 insert into [dbo].[User] (id, permission_id)
 values (1, (select [id] from [permission] where [name] = 'write')),
       (......

I need to Add Migration for these Scripts, How I can create migration for SQL queries?

Answer 1

install the ef core tools ( reference )

dotnet tool install --global dotnet-ef

issue a command from the cli to create a migration ( reference )

dotnet ef migrations add InitialCreate

You will also need to have a reference to Microsoft.EntityFrameworkCore.Design in the startup project.

In a lot of my work I have a web assembly (api) and a separate model/repository assembly, so a typical migration command for me looks like

dotnet ef migrations add MigraitonName -s StartupProject -p RepositoryProejct -c DbContext

Once you have a migration you can run the following command to update your database

dotnet ef database update
