UPDATE daily_tasks SET date = REPLACE(date, date, CONVERT(VARCHAR(255), daily_tasks.date, 102)) WHERE 1;
But, it doesn't work.
Ideally you should be storing your dates as bona-fide date columns, not as text. That being said, the date text
'2018-08-08' is in fact in an ISO format, and would still allow you to do things like sort and compare against other date literals, so it is not so bad.
But converting this text to a
'08.08.2018' format is the wrong thing to do. If a anything, you might want to consider adding a new date column
new_date to store this date information. Do that, and then populate it with:
UPDATE daily_tasks SET new_date = TRY_CONVERT(datetime, date);
