Get MySQL DATE_ADD to work the same as PHP

Question

In PHP if you do:

$date = "2013-08-31";
$nextdate = strtotime(date("Y-m-d", strtotime($date)) . " +1 month");
$date = date( "Y-m-d", $nextdate );
echo $date;

You get 2013-10-01 ie the month has rolled over since there are only 30 days in September.

In MySQL if you do:

UPDATE member_account SET NextBillDate = '2013-08-31'
SELECT DATE_ADD(NextBillDate, INTERVAL 1 MONTH) FROM member_account

You get 2013-09-30 ie no roll-over

In Java it's the same thing:

GregorianCalendar oDate = new GregorianCalendar();
SimpleDateFormat Sdf = new SimpleDateFormat( "yyyy-MM-dd" );
try{oDate.setTime(Sdf.parse("2013-08-31"));} catch (Exception e) {}
String sTodayDate = Sdf.format( oDate.getTime() );

oDate.add(Calendar.MONTH, 1);
String sTodayDate2 = Sdf.format( oDate.getTime() );

sTodayDate2 is "2013-09-31"

Is there a way of making MySQL or Java behave the same way as PHP so it will rollover if the number of days in the month is exceeded?

Answer 1

Found this little Java snippet, does the trick:

    int oldDay = oDate.get(Calendar.DAY_OF_MONTH);
    oDate.add(Calendar.MONTH, 1);

    // If the old DAY_OF_MONTH was larger than our new one, then
    // roll over to the beginning of the next month.
    if (oldDay > oDate.get(Calendar.DAY_OF_MONTH)){
        oDate.add(Calendar.MONTH, 1);
        oDate.set(Calendar.DATE, 1);
    }

    String sTodayDate2 = Sdf.format( oDate.getTime() );
