What is a better way to program the following SQL:

str_to_date(
  concat(convert(D.DAY, CHAR(2)),
  '-',
  convert(M.MONTH, CHAR(2)),
  '-',
  convert(M.YEAR, CHAR(4))),
  '%e-%m-%Y' ) as AMOUNT_DATE

I want to convert the columns D.DAY, M.MONTH, and M.YEAR to a date field using MySQL. The above works, but seems much more complicated than it needs to be. (If there's an ANSI SQL way to do it, that would be even better.)

Thank you!
