Probably you don’t have write permissions to create your database on your phone/tablet.

You should make sure you create a database where your path is accesible, so you can use something like this:

function OpenDB(p : String){
    connection = "URI=file:" + Application.persistentDataPath + "/" + p;
    dbcon = new SqliteConnection(connection);
    dbcon.Open();
}

thanks dude i will try it now :slight_smile:

no error but still data is not showing, and its kinda wierd in my code persistentDataPath is not highlighted, im sorry im not really good in coding :frowning:

Is your tablet is Android or iPad ? I think that is just small issue with database path.

im using android tablet, i think the problem is the database that was stored in the computer during test is not included when we build it and deploy to my tab, any idea in how to fix it?
