    var db = require('odbc')()
        , cn = "Dsn=Oracle;UID=saikrishnabobba;PWD=<password>;"
    //open the connection
    db.open(cn, function (err) {
        if (err) {
          return console.log(err);
    // Run a sample query
         db.query("select * from COUNTRIES", function (err, rows, moreResultSets) {
          if (err) {
