I have a field in my database as text, which contain a D-M date value. The year is a new field. So ORDER BY year ASC is not that difficult. Now I wanted to also ORDER BY date. Only problem is, ORDER BY year ASC, ORDER BY date does not work. I think because of the text field. Is it still possible to sort them on year, month, day ASC?
Thanks!

Use SUBSTRING_INDEX():
... ORDER BY year ASC, SUBSTRING_INDEX(date, '-', -1) ASC, SUBSTRING_INDEX(date, '-', 1) ASC
SUBSTRING(date, '-', -1)
will give you everything after the -
(the month).SUBSTRING(date, '-', 1)
will give you everything before the -
(the day).Upvotes: 2
