Answer 1

I think you just want str_to_date() :

select str_to_date('04.12.2020', '%d.%m.%Y')

Answer 2

It sounds like you have a date as a string? (ie. the "04.12.2020"). MySql has a STR_TO_DATE() function:

select str_to_date('04.12.2020', '%d.%m.%Y')

That should convert it to an actual date datatype.

If needed an actual date can then be formated in which ever way you want or just visualized depending on what you're trying to do with DATE_FORMAT():

select date_format(date, '%Y-%m-%d')
