Hello everyone.
I want to use SQLite with my Expo react native project. So I downloaded DB browser for SQLite and created the database and tables before loading them into my project.
Now I have the pre-populated database that I want to load into my project. I had several problems like this database doesn’t exist …etc. However I solved it by having a database module:
// database.js
import * as SQLite from 'expo-sqlite';
module.exports = SQLite.openDatabase('myDb.db');
And then import it in my Home Page in Screens folder:
import Database from '../db/database';
function myFunction(){
console.log("Enter Function");
console.log(Database);
Database.transaction(function(txn) {
console.log("Enter Transaction");
txn.executeSql(
"INSERT INTO users (name, email, password) VALUES ('Lama', 'lama@gmail,com', 'lam123');",
); //end txn
}, function (error){
console.log(error);
},
function(){
console.log("Success");
});
}//end myFunction()
The console logs:
Enter Function
WebSQLDatabase {
"_currentTask": null,
"_db": SQLiteDatabase {
"_closed": false,
"_name": "myDb.db",
},
"_running": false,
"_txnQueue": Queue {
"length": 0,
},
"exec": [Function anonymous],
"version": "1.0",
}
Enter Transaction
Error code 1: no such table: users

I don’t really know what I’m missing here, I have tried the code to create Another database and it works and adds records (although I can’t find where the database is located in my laptop). I also tried to add a record from the DB browser to myDb and it works:
I found this question asked before but there are not helping answers: SQLite Expo API, no such table in pre-populated file?
Thank you in advance!
