I'm working on a project where I'm downloading and saving data from web to sqlite database. A few minutes ago I receive a strange exception to our server from a user which is saying that the sqlite database is already closed..and I just checked the whole file where the exception happened and I'm not calling dbHelper.close(); .

I' m using sqlite on iphone. I have table with 200 000 records. It' s size is small, only 2 MB. I' m doing standard select(3 collumns) with two simple condtions. I' m operating only on integer values( in return and condtion). All data are unique. I'm get usually only 10-50 records from database. In spite of that my query take 3 sec. It' s a lot of time. How i can improve this ? Edit: I can't load my table with other thread. NSString * query = [ NSString stringWithFormat:@"SELECT rRozklad.hour, rRozklad.minute, rRozklad.marks FROM rRozklad.idOkres=%i AND rRozklad.idPolaczeniaLinie=2 ORDER by rRozklad.hour, rRozklad.minute", okres]; NSLog(@"%@", query); const char * querystring = [ query UTF8String ]; sqlite3_stmt * statment; if(sqlite3_prepare_v2(database, querystring, -1, &statment, nil) == SQLITE_OK){ while(sqlite3_step(statment) == SQLITE_ROW){ NSMutableArray * temp = [[NSMutableArray alloc] initWithCapacity:2];

Following is a snippet that is meant to fetch the data from the database. But when i click the submit button to see the data, the browser keeps on looking for the data but never displays anything (the browser doesn't show the next page but keeps on looking on the same page) .

Snippet that fetches the data : public void doGet(HttpServletRequest request,HttpServletResponse response) throws IOException,ServletException { try { Context context = new InitialContext(); DataSource dataSource = (DataSource)context.lookup("java:comp/env/jdbc/MyDatasource"); Connection connection = dataSource.getConnection(); String sqlStatement = "SELECT * FROM INFORMATION"; PreparedStatement statement = connection.prepareStatement(sqlStatement); ResultSet set = statement.executeQuery(); PrintWriter writer = response.getWriter(); response.setContentType("text/plain");

I want to be able to prompt the users to enter the details required for the app only when it starts up for the first time (not other times). These details will be held in a database on the phone. Would it be better to check the database each time or put these details in a shared preference? Furthermore, is this type of activity even possible on Android?

I'm making websites for a company where users have to "register" with names and a lot of different information to attend the event. (It's a video-event - info would be name, e-mail etc.) I now got a Wordpress webpage, at the blanket doesn't necessary need to be on the site, but can open in a separate window. I need to, somehow make it easy for admin to look at the users who registered, send them e-mails etc. Make a list of everyone who register, for the admin to see. How would be the easiest way to do this? I know how to make a form, and pull the information into the database.. Any good ideas, plugins or examples?? Thanks
