  /* result = {
    tables: {
      person: {
        name: 'person',
        columns: {
          'id': { name: 'id', notNull: true, primaryKey: true, type: 'integer', length: '11' },
          'name': { name: 'name', notNull: true, type: 'varchar', length: '255' },
          'email': { name: 'email', notNull: false, type: 'varchar', length: '100' },
