You can achieve this using

cordova-sqlite-ext

for install,

cordova plugin add cordova-sqlite-ext --save

A Cordova/PhoneGap plugin to open and use sqlite databases on Android/iOS/Windows with REGEXP (Android/iOS) and pre-populated databases (Android/iOS/Windows)

var db = null;
document.addEventListener('deviceready', function() {
  db = window.sqlitePlugin.openDatabase({name: 'demo.db', location: 'default'});
});

IMPORTANT : Like with the other Cordova plugins your application must wait for the deviceready event. This is especially tricky in Angular/ngCordova/Ionic controller/factory/service callbacks which may be triggered before the deviceready event is fired.

Here's detailed example for this.
