The <info>%command.name%</info> command loads data fixtures from your application:

  <info>php %command.full_name%</info>

Fixtures are services that are tagged with <comment>doctrine.fixture.orm</comment>.

If you want to append the fixtures instead of flushing the database first you can use the <comment>--append</comment> option:

  <info>php %command.full_name%</info> <comment>--append</comment>

By default Doctrine Data Fixtures uses DELETE statements to drop the existing rows from the database.
If you want to use a TRUNCATE statement instead you can use the <comment>--purge-with-truncate</comment> flag:

  <info>php %command.full_name%</info> <comment>--purge-with-truncate</comment>

To execute only fixtures that live in a certain group, use:

  <info>php %command.full_name%</info> <comment>--group=group1</comment>
