<![CDATA[Qml: How to use your own .db file]]>Good day!
I am new to qml, so I'm sorry if it's a dumb question.
I am currently learning a way to connect my own .db file to qml.
I have found that I should use QtQuick.LocalStorage 2.0 as a way to connect my db to qml.
From what I understand from the documentation is that you can use QQmlEngine::offlineStoragePath() to find the path of the storage location where you can find and put the database. My database file name is test.db
This is my test code if I can display the data.

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick.LocalStorage 2.15

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
    Text {
        id: name
        //to find the path
        text: offlineStoragePath
    }
    Item {
        Component.onCompleted: {
            var db = LocalStorage.openDatabaseSync("test", "1.0", "Example database", 10000);
            db.transaction( function(tx) {
                var result = tx.executeSql('select * from test');
                for(var i = 0; i < result.rows.length; i++) {
                        print(result.rows[i].text);
                    }
                });
        }
    }

}

Then the error "no such table: test Unable to execute statement" appears.
I had also checked the db file and run "SELECT * FROM test" on the sqlite browser and it works fine.
Any ideas and suggestions can help me, and if there's a better way of doing it can also help.
Thank you very much for your time.
