What are Go ORM migrations and how do I use them?

Go ORM migrations are tools that help manage database schema changes in Go applications. They allow you to create, update, and delete database tables and fields in a structured way.

Can you give me an example of how to create a migration?

Sure! To create a migration, you typically define a new migration file with the necessary SQL commands or use a migration library to generate it for you. For example, using the golang-migrate library, you can run migrate create -ext sql -dir db/migrations create_users_table.

How do I apply the migration to my database?

You can apply the migration using the command migrate up followed by the migration file path. This will execute the SQL commands in the migration file and update your database schema.

What if I need to roll back a migration?

To roll back a migration, you can use the command migrate down. This will revert the last applied migration, undoing the changes made to the database.
