How to get all the data from a table?

Question

firebird

Good afternoon. Is there anyone who works with Firebird from NodeJS? There is a DB with the following tables:
I should deduce all fields of the COMPUTERS table. Here is my code:

const Firebird = require('node-firebird')

let options = {}
options.host = '127.0.0.1'
options.port = 3050
options.database = `${__dirname}/Global.fdb`
options.user = 'SYSDBA'
options.password = 'masterkey'

let computers = Firebird.attach(options, function (err, db) {
  if (err) throw err
  db.query('SELECT * FROM COMPUTERS', (err, result) => {
    console.log(result)
    db.detach()
  })
})

console.log(computers)

I'm not strong in the database ... Tell me, please, how to do this?
