Question

This is my database:

Here I have to check the query current date+status=Q information and get the count value.

This is my code:

public class TodayQ {
    public int data() {
         int count=0;
        Date date = new Date(timestamp);
DateFormat dateFormat = new SimpleDateFormat ("yyyy-MM-dd");
System.out.println( dateFormat.format (date));

        // count++;

        try {
            Class.forName("com.mysql.jdbc.Driver");
            Connection con = DriverManager.getConnection(
                    "jdbc:mysql://localhost:3306/pro", "root", "");

            PreparedStatement statement = con
                    .prepareStatement("select * from orders where status='Q' AND date=CURDATE()");
            ResultSet result = statement.executeQuery();
            while (result.next()) {
                // Do something with the row returned.
                count++; // if the first col is a count.
            }

        }

        catch (Exception exc) {
            System.out.println(exc.getMessage());
        }

        return count;
    }

}

Here I have to edit the date is (yyyy-mm-dd) format. Now I got the output. But I wish to use timestamp on my database. So how is converted timestamp to date in Java. How is use that code in my code?

You can achieve the same using mysql functions. Hope the following query gives you the desired output.

select * 
from orders
where status='Q' AND 
      date_format(from_unixtime(date),'%Y-%m-%d') = current_date;
