node-hdb-async.js

'use strict';
var util = require('util');
var client = require('./client');

var fields = ['SCHEMA_NAME || \'.\' || TABLE_NAME as TABLE'];
var sql = util.format('select top 5 %s from TABLES', fields.join(','));

const connect = async () =>
  await client.connect();

const executeAndfetchRows = async () =>
  new Promise((resolve, reject) =>
    client.exec(sql, (err, rows) => resolve(rows)));

const disconnect = async (rows) => {
  await client.disconnect();
  return rows;
}

const done = (rows) => {
  console.log(util.inspect(rows, {
    colors: true
  }))
}

connect()
  .then(executeAndfetchRows)
  .then(disconnect)
  .then(done);
