How to compare 2 dates in SQL Server 2000 DB using Java?

Question

How do you compare 2 dates in SQL Server 2000 DB using Java?
Let's say we have two fields: Date Reported and Target Finish Date.
Date Reported is 09-10-2004 09:55:55: PM
Target Finish Date is 09-12-2004 11:59:59: PM
What i want to happen is i want to convert both dates to days and get the difference of the two.
can SQL Server 2000 DB do this?

Answer 1

it doesnt wrk.
ok here's what i did:
iv tested a simple code for this case.
I created a table name tblDate which has 3 columns namely date_ID, date_From (datatype datetime), date_To (datatype datetime).
I inserted 1 row: date_ID has the value 1, date_From has the value 10/22/2004, and date_To has the value 10/24/2004.
i run the java code below:
int days = 0;
          String query = "SELECT date_From, date_To cast(date_From-date_To AS int) AS Diff FROM tblZoo WHERE date_ID = '1'";
          try
               DBConnect db = new DBConnect();
               db.openCon();
               ResultSet rs = db.execute(query);
               while(rs.next())
                    days = rs.getInt("Diff");
               db.closeCon();                         
          catch (Exception ex)
               System.out.println("Error on Execution: " + ex);
          return days;___________
an error occurred: Error on Execution: java.lang.nullpointerexception
