def run_migrations_offline():
url = config.get_main_option("<STR_LIT>")<EOL>context.configure(url=url)<EOL>with context.begin_transaction():<EOL><INDENT>context.run_migrations()<EOL><DEDENT>
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.
