Mysql 如何选择并在7天内前进

有人能解释一下，如果WHERE子句中有一个日期范围，我将如何选择一个日期，并以7天为间隔向前推进

下面是我的SQL示例：

SELECT DATE(*TIMESTAMP*) + (DATE_ADD(DATE(*TIMESTAMP*), INTERVAL 7 DAY)) as `interval`
WHERE digital_lead.received <= '2014-12-16 08:37:00' AND
digital_lead.received >= '2014-11-14 08:37:00'

给定WHERE子句中的日期范围，SELECT语句向前移动7天

有什么建议吗？

在这个答案的帮助下：通过类似的问题，我能够做到：

select date_add('2014-11-14 08:37:00', INTERVAL (row) DAY) FROM
(
SELECT @row := @row + 7 as row FROM 
(select 0 union all select 1 union all select 3 union all select 4 union all select 5 union all select 6 union all select 6 union all select 7 union all select 8 union all select 9) t,
(select 0 union all select 1 union all select 3 union all select 4 union all select 5 union all select 6 union all select 6 union all select 7 union all select 8 union all select 9) t2, 
(select 0 union all select 1 union all select 3 union all select 4 union all select 5 union all select 6 union all select 6 union all select 7 union all select 8 union all select 9) t3, 
(select 0 union all select 1 union all select 3 union all select 4 union all select 5 union all select 6 union all select 6 union all select 7 union all select 8 union all select 9) t4, 
(SELECT @row:=-7) q
WHERE @row<=DATEDIFF('2014-12-16 08:37:00' , '2014-11-14 08:37:00')
) z

我如何在结果中包括开始日期？从21日开始？感谢我的回答；只需修改这两个三个事实上，开始日期显示为两个时间戳。它仍然从21日开始？

select date_add('2014-11-14 08:37:00', INTERVAL (row) DAY) FROM
(
SELECT @row := @row + 7 as row FROM 
(select 0 union all select 1 union all select 3 union all select 4 union all select 5 union all select 6 union all select 6 union all select 7 union all select 8 union all select 9) t,
(select 0 union all select 1 union all select 3 union all select 4 union all select 5 union all select 6 union all select 6 union all select 7 union all select 8 union all select 9) t2, 
(select 0 union all select 1 union all select 3 union all select 4 union all select 5 union all select 6 union all select 6 union all select 7 union all select 8 union all select 9) t3, 
(select 0 union all select 1 union all select 3 union all select 4 union all select 5 union all select 6 union all select 6 union all select 7 union all select 8 union all select 9) t4, 
(SELECT @row:=-7) q
WHERE @row<=DATEDIFF('2014-12-16 08:37:00' , '2014-11-14 08:37:00')
) z
