You should probably post your code and complete error message here before anyone can lend a hand.

Whole code

import {WebService} from './services/webservice';
import {StatusBar} from 'ionic-native';
import {DatabaseHelper} from './services/DatabaseHelper';
import {Storage, SqlStorage} from 'ionic-angular';

  template: '<ion-nav [root]="rootPage"></ion-nav>'
export class MyApp {
  rootPage: any = LoginTabPage;
  //public db: SQLite;
  db : DatabaseHelper;
  storage: Storage = null;

  constructor(platform: Platform) {

    platform.ready().then(() => {
            this.db = new DatabaseHelper();
            let options = {
              name: '_Novity',              // the name of the database
              backupFlag: SqlStorage.BACKUP_LOCAL, // where to store the file
              existingDatabase: false              // load this as an existing database
   = new Storage(SqlStorage, options);

            var sql = 'INSERT INTO ' + this.db.sqtable_UserInfo + ' ( '+this.db.COLUMN_userId +' , '+ this.db.COLUMN_password + ' ) VALUES ( ?, ?)';
  , ['varshil','shah']).then((res) => {
              }, (err) => {
                  console.log('Error: ', err.res);
