What are migrations in ORM?
An example of an AI chatbot conversation about migrations in Object-Relational Mapping (ORM).
What are migrations in ORM?
Migrations in ORM are a way to manage changes to the database schema over time, allowing you to evolve your database structure.
How do I create a migration in an ORM like Sequelize?
In Sequelize, you can create a migration using the command npx sequelize-cli migration:generate --name migration_name. This generates a new migration file.
Can I roll back a migration if something goes wrong?
Yes, you can roll back a migration using the command npx sequelize-cli db:migrate:undo, which reverts the last migration applied.
What happens if I forget to run migrations after changing the model?
If you forget to run migrations, your database schema will not reflect the changes in your model, leading to potential errors.
