The <info>doctrine:schema:update</info> command generates the SQL needed to
synchronize the database schema with the current mapping metadata of the
default entity manager.

For example, if you add metadata for a new column to an entity, this command
would generate and output the SQL needed to add the new column to the database:

<info>php app/console doctrine:schema:update --dump-sql</info>

Alternatively, you can execute the generated queries:

<info>php app/console doctrine:schema:update --force</info>

You can also update the database schema for a specific entity manager:

<info>php app/console doctrine:schema:update --em=default</info>
