Examples

The following example creates the stamps database and the hobbies database, and then moves the stamps database into the hobbies database:

Promise.all([
  client.query(
    q.CreateDatabase({ name: 'stamps' })
  ),
  client.query(
    q.CreateDatabase({ name: 'hobbies' })
  ),
])
.then(([stamps, hobbies]) => client.query(
  q.MoveDatabase(stamps.ref, hobbies.ref)
))
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))
