如何從只記錄最近三天的表中選擇數據

Question

我通過 mysql NOW() 函數在“日期”字段中記錄了數據。 我想 SELECT 記錄最近三天（今天，昨天和前天）的數據，但不知道這樣做。

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

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

另一種方法是：

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