  • Dear friends,



    I have the problem with date format. I receiving the date with the
    format dd/mm/yyyy. But I can upload to MySQL only in the format of
    yyyy-mm-dd.



    how should I handle this situation, for this I've created these code
    lines.But I have some problem with these line. please help me to solve
    this problem.



    rs.getString("DATA_SCAD1")// where the source from .xls files

    String pattern = "yyyy-MM-dd";

    SimpleDateFormat format = new SimpleDateFormat(pattern);

    try {

    Date date = format.parse("DATA_SCAD1");

    System.out.println(date);

    } catch (ParseException e) {

    e.printStackTrace();

    }

    System.out.println(format.format(new Date()));



    this out put gives me Tue Apr 03 00:00:00 IST 2007



    But I need the date format in yyyy-mm-dd.



    regards,

    maza



    thanks in advance.

    but wouldn't it be a lot simpler to just split the string on "/" and juggle then values around and put "-" between them.

    Don't be so hostile, dear sir.

     

    But yeah, if it's a string you receive, and a string you must produce, then splitting "/", and concatenating in the right order is the simplest solution.

    Why not? He's clearly an idiot.

  • To move between formats :

    SimpleDateFormat inFmt = new SimpleDateFormat("dd/MM/yyyy");

    SimpleDateFormat outFmt = new SimpleDateFormat("yyyy-mm-dd");

    String out = outFmt.format(inFmt.parse("22/11/2007"));

     

    But if you're insert into a date column in a database :

    preparedStatement.setDate(colNum, inFmt.parse("22/11/2007"));

    should be fine.

    It wasn't as harshly meant as you might have interpreted it. I just found it quite weird to address people whom you have never known and will probably never meet as "friends", my more social disturbed side found this weird and plainly wrong, because he can't seriously believe everyone to read that text to be his friend, and i thus thwarted him in his attempt to casually make me his friend by stating the opposite.

    Well, he's using such language at the forum where TubeRodent is lurking... Probably, you're right. 8=]



  • I haven't tested this, but try:

     

                    String unparsed = rs.getString("DATA_SCAD1");
                    if (unparsed == null)
                        return;
    
                SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
                try
                {
                    Date date = format.parse(unparsed);
                    System.out.println(format.format(date));
                }
                catch (ParseException e)
                {
                    e.printStackTrace();
                }

     It
    would seem that way, it's the kind of thing about 10 seconds of
    thinking about or  5 seconds of googleing would find the answer

     also in the OP's example won't this line always throw and exception


    Date date = format.parse("DATA_SCAD1");

    it's been a few years since i've done any java but according to my calculations that's never going to work

    I'm a Java nut. I parsed the invisible sarcasm tag without any problems. And I would have gone the google path, instead of asking this question here...

    Neither, it just took him a while to type the code in.
