Example: knex js join schema

exports.up = (knex) => {
  knex.schema.createTable('bookings', (table) => {
    table.increment('booking_id').primary()
    table.foreign('user_id').references('user_id').inTable('users').notNullable().onDelete('CASCADE').index()
    table.foreign('room_id').references('room_id').inTable('rooms').notNullable().onDelete('CASCADE').index()
    table.integer('total_person').notNullable().defaultTo(0)
    table.datetime('booking_time').notNullable().defaultTo(knex.fn.now())
    table.string('noted').notNullable()
    table.datetime('check_in_time').defaultTo(knex.fn.now())
    table.datetime('check_out_time').defaultTo(knex.fn.now())
    table.timestamp('created_at').defaultTo(knex.fn.now())
    table.timestamp('update_at').defaultTo(knex.fn.now())
    table.timestamp('delete_at').defaultTo(knex.fn.now())
  })
}

exports.down = (knex) => knex.schema.dropTable('bookings')
