How to select data from a table recorded only in the last three days (use PHP, MySQL)

Question

I wrote data to the 'date' field with the mysql NOW () function. I want to SELECT the data that was recorded the last three days (today, yesterday and the day before yesterday), but do not intend to do this. I am trying my code as it should, please help.

SELECT * FROM tlb_students WHERE date ...? ... ORDER BY date DESC LIMIT 20

Answer 1

SELECT * FROM tlb_students WHERE date >= NOW() - INTERVAL 3 DAY ORDER BY date DESC LIMIT 20 

Answer 2

 WHERE date >= ( CURDATE() - INTERVAL 3 DAY ) 

Answer 3

 WHERE date >= subdate(NOW(), 2) 

Answer 4

Another way to do this:

 SELECT * FROM tlb_students WHERE date < DATE_ADD(CURDATE(),INTERVAL -3 DAY)
