I was having the same problem, you need to verify if the Database was initialized in App.
Example using Expo
import React, { useEffect, useState } from 'react';
import AppLoading from 'expo-app-loading';
const App = () => {
const [InitializedDatabase, setInitializedDatabase] = useState(false);
useEffect(() => {
let tableValues = { table: "User", column: "Username TEXT, Password TEXT" };
createTable(tableValues).finally(() => setInitializedDatabase(true));
}, []);
if (!InitializedDatabase) {
return <AppLoading />;
}
return (
<View />
);
}
const createTable = (value) =>
new Promise((resolve, reject) =>
db.transaction((tx) =>
tx.executeSql(`CREATE TABLE IF NOT EXISTS ${value.table} (${value.column});`,
[],
(_, { rowsAffected, insertId }) => resolve(insertId),
(_, error) => reject(error)
)));
