在java中获取今天的日期

Question

This is my database:

date          status
1343469690     Q
1343470540     C
1343470556     P

I have written this code:

public class TodayQ {

    public int data() {
        int count = 0;
        //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;
    }
}

It works successfully when date is in yyyy-mm-dd format. But now my date is a timestamp in 1343469690 format. How is get the count value?

Answer 1

If it's actually a Timestamp, then you have the date: See http://docs.oracle.com/javase/7/docs/api/java/sql/Timestamp.html . Converting a TimeStamp to a Calendar (http://docs.oracle.com/javase/7/docs/api/java/util/Calendar.html) is trivial: see the Calendar.setTimeInMillis() method.

Answer 2

Replace CURDATE() into FROM_UNIXTIME() .According to your code, you should change likes this;

      PreparedStatement statement = con.prepareStatement("select * from orders where status='Q' AND date=FROM_UNIXTIME(date,'%Y %M %D')");
