Functions

run_migrations_offline()	Run migrations in 'offline' mode.
run_migrations_online()	Run migrations in 'online' mode.

env.run_migrations_offline()

Run migrations in ‘offline’ mode.

This configures the context with just a URL and not an Engine, though an Engine is acceptable here as well. By skipping the Engine creation we don’t even need a DBAPI to be available.

Calls to context.execute() here emit the given string to the script output.

env.run_migrations_online()

Run migrations in ‘online’ mode.

In this scenario we need to create an Engine and associate a connection with the context.
