  <pre><code>var Teradata = require('node-teradata');  
  
  
  var config = { 
  url: 'jdbc:teradata://abc.com/database=abab', 
   username: '****',   
    password: '****',  
    driver: './jars/',  
    minPoolSize: 1,
      maxPoolSize: 100,   
      keepalive: {   
        interval: 60000,   
        query: 'SELECT 1',   
        enabled: true

  };   
  
  var teradata = new Teradata(config);
  
  var sql = "select name,QTY from products where id='700018'";
