Question

I have an app pulling information from a SQLite database. It works perfectly on the iPhone Simulator, but I don’t get anything when I test on a device. Are there differences to using a database between the two? I’ve tried looking all over and can’t find anything that is helping. I see this problem is common on google, I just haven’t found a solution thats worked for me.

I have put break points in and tried to debug this, on the actual device it never gets passed while (sqlite3_step(statement) == SQLITE_ROW), it is always returning SQLITE_DONE. I can’t figure out why this would change on a device. Any help would be appreciated, advice on SQLite, or if the code could be improved etc. Thanks.

NSString *qsql = @"SELECT Distinct State FROM School";
    sqlite3_stmt *statement;

    if (sqlite3_prepare_v2(db, [qsql UTF8String], -1, &statement, nil) == SQLITE_OK) 
    {
        while (sqlite3_step(statement) == SQLITE_ROW) 
        {
            char *colState = (char *) sqlite3_column_text(statement, 0);
        NSString *state = [[NSString alloc] initWithUTF8String:colState];

        [states addObject:state];
        [state release];
    }
    sqlite3_reset(statement);
}
return states;

}

The first thing that comes to mind is that the database is installed properly on the simulator but not on the phone.
