import * as SQLite from 'expo-sqlite' not working

i am using expo to build a app.

here, 

`import * as SQLite from 'expo-sqlite';

const db = SQLite.openDatabase("db.db");

is not working while

import { SQLite } from "expo-sqlite"; is working.

when i use the first method, it is getting SQLite.openDatabase is not a function error.

actually what is the difference with these? anyone have an idea?

When you do import * as SQLite from 'expo-sqlite'; you are actually importing all the modules from the expo-sqlite by writing * as SQLite , and its stored as SQLite variable which then you are using to create an openDatabase.

But when you do import { SQLite } from "expo-sqlite"; you are only importing the SQLite module from the expo-sqlite package. And after that you are using it to create a database.

Basically its like sometimes in some file you have multiple functions like suppose App.js

export const add =() => {

}


export const bol = () => {

}

Then suppose in Home.js you need to import ,

So if you want only the add function then you will do

import {add} from 'App.js'

or you want both so <

import {add,bol} from 'App.js'

and another way of importing both is by

import * as Func from 'App.js'

And now you can access each by Func.add and Func.bol

Hope it helps. feel free for doubts
