使用doctrine从Symfony2中的外部数据库导入表

composer require doctrine/doctrine-migrations-bundle

doctrine_migrations:
    dir_name: "%kernel.root_dir%/DoctrineMigrations"
    namespace: Application\Migrations
    table_name: migration_versions
    name: Application Migrations

php app/console doctrine:migrations:generate

public function up(Schema $schema)
{
    // this up() migration is auto-generated, please modify it to your needs
    $this->abortIf($this->connection->getDatabasePlatform()->getName() != 'mysql', 'Migration can only be executed safely on \'mysql\'.');

    $this->addSql('CREATE TABLE my_table (id INT AUTO_INCREMENT NOT NULL, name VARCHAR(255) DEFAULT NULL, PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB');
}

public function down(Schema $schema)
{
    // this down() migration is auto-generated, please modify it to your needs
    $this->abortIf($this->connection->getDatabasePlatform()->getName() != 'mysql', 'Migration can only be executed safely on \'mysql\'.');

    $this->addSql('DROP TABLE my_table');
}

php app/console doctrine:migrations:migrate
