1、首先获取一个最近1000天的时间列表，如果不够可以按规则再加
SELECT adddate(CURDATE(),-(t2.i * 100 + t1.i * 10 + t0.i)) date
FROM (SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 ) t0,
(SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9) t1,
(SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9) t2
2、然后获取最近30天的开始时间 DATE_SUB(CURDATE(), INTERVAL 30 DAY)
3、最后截取最近30天的时间，在步骤1的外面包一层然后 BETWEEN DATE_SUB(CURDATE(), INTERVAL 30 DAY) AND CURDATE()就可以了。
SELECT * FROM (SELECT adddate(CURDATE(),-(t2.i * 100 + t1.i * 10 + t0.i)) date FROM (SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9 ) t0,
(SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9) t1,
(SELECT 0 i UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4 UNION SELECT 5 UNION SELECT 6 UNION SELECT 7 UNION SELECT 8 UNION SELECT 9) t2) dateWHERE date.date BETWEEN DATE_SUB(CURDATE(), INTERVAL 30 DAY) AND CURDATE();
效果是
