Read Existing SQLite Database File and Load Data


I am new to Ionic and I have been working on SQLite but I cannot make this work for a week now, and its quite frustrating :confused: .
I have tried some plugins such as litehelpers/Cordova-sqlite-storage, litehelpers/cordova-sqlite-ext, and some others but it doesnt seem to work for me. Some plugins return “Cannot find sqlitePlugin” error.
I also tried openDatabase() { this.sqlite.create({name: ‘data.db’, location: ‘default’}).then((db: SQLiteObject) but it does not read my existing database. BTW, I am using a real Android device to test.

What I want to achieve is, just load the data from the database that I previously created using DB Browser for SQLite. I have tried putting the sqlite file into my www but its still not working. I got errors like cannot open database. The database that I am talking to about already has tables and data stored so I will just be reading them and showing data to the user. Is it possible to achieve this?

I have tried some solutions on some posts like Load pre populated SQLite database - impossible in Ionic 2 and How to make SQLite in ionic-native use cordova-sqlite-ext?

Its difficult to imagine creating hundreds or thousands of INSERT statements that is why I just want to load the database with existing tables and data.

Thanks! Any help will be gladly appreciated. :slight_smile: .

Anyway, below is my ionic info:

1 Like doesnt seem to help me because I think that Ionic framework used here is an old version.

Hi. I hope someone notice my inquiry. By the way, the app that I am creating is an offline language tutorial.

Hello, do you still need help?

I don’t need help on this anymore. I just became helpless on this. What I did is put all the data in a json file and encode them into something. Thanks!

Do you think it’s better than having a database?

Of course it is not. Its just that I really do not know how to solve my problem and I became helpless. I even searched about it on search engines for one week without success. But anyway, thanks for your willingness to help. :slight_smile:

Well i had the same problem, i actually spent weeks trying to get it to work and finally succeeded. if you or anyone else are still interested on how I was able to do it let me know!

Please help me on this. I am struggling on it for a week !

First of all, you need to import 3 plugins:

Then import the SQLite in your ts file:

import { Component } from '@angular/core';
import { SQLite } from "ionic-native";
import { Platform, NavController, PopoverController } from 'ionic-angular';

export class HomePage {
    public storage: SQLite;
    public itemList: Array<Object>;
 constructor(public popoverCtrl: PopoverController, public navCtrl: NavController, public platform: Platform) {

   this.itemList = [];

        this.platform.ready().then(() => {
   = new SQLite();
  { name: "data.db", location: 'default', createFromLocation: 1 }).then((success) => {
      "SELECT * FROM art", {}).then((data) => {
                    let rows = data.rows;
                    for (let i = 0; i < rows.length; i++) {
                            id: rows.item(i).id
                }, (error) => {
          "Unable to execute sql " + JSON.stringify(error));
         }, (err) => {
      "Error opening database: " + err);

Don’t forget to add the file data.db in www/ directory.

I hope I didn’t miss anything. Let me know if it works.

Do I have to call the Copy() method to copy the Database ? Or just including the cordova-plugin-dbcopy Plugin is enough ?

Just include the Plugin. That’s how it worked with me!

Thank You. Will try it.

It does not work. Throws error: No Such table. Whereas I have the correct table in the Database I created using Sqlite browser.

In what folder did you add the database?

Do you have any idea why should I include those 3 if you used just one?

I found one of the way to play with existing DB on Deploy Ionic 3 App with pre-populated SQLite DB from MySQL DB

Though I previously said that I put my data into json, I was able to solve it in another project. I just followed and put my db in www folder. That’s it.

Hi…I tried to do the same i put my db file in www folder and assets folder as well but it is still showing “no such table exists” error.Please let me know if i missed something.

Are you running it using a real device?
