    We have several examples on the website. Here is the first one to get you started:

    // Create a table
      .createTable('users', function(table) {
      // ...and another
      .createTable('accounts', function(table) {
      // Then query the table...
      .then(function() {
        return knex('users').insert({ user_name: 'Tim' });
      // ...and using the insert id, insert into the other table.
      .then(function(rows) {
        return knex('accounts').insert({ account_name: 'knex', user_id: rows[0] });
      // Query both of the rows.
      .then(function() {
        return knex('users')
          .join('accounts', '', 'accounts.user_id')
          .select('users.user_name as user', 'accounts.account_name as account');
      // .map over the results
      .map(function(row) {
      // Finally, add a .catch handler for the promise chain
      .catch(function(e) {
