const knex = require('knex')({
  client: 'sqlite3',
  connection: {
    filename: './data.db',
  },
});

try {

  // Create a table
  await knex.schema
    .createTable('users', table => {
      table.increments('id');
      table.string('user_name');
    })
    // ...and another
    .createTable('accounts', table => {
      table.increments('id');
      table.string('account_name');
      table
        .integer('user_id')
        .unsigned()
        .references('users.id');
    })

  // Then query the table...
  const insertedRows = await knex('users').insert({ user_name: 'Tim' })

  // ...and using the insert id, insert into the other table.
  await knex('accounts').insert({ account_name: 'knex', user_id: insertedRows[0] })

  // Query both of the rows.
  const selectedRows = await knex('users')
    .join('accounts', 'users.id', 'accounts.user_id')
    .select('users.user_name as user', 'accounts.account_name as account')

  // map over the results
  const enrichedRows = selectedRows.map(row => ({ ...row, active: true }))

  // Finally, add a catch statement
} catch(e) {
  console.error(e);
};
