mysql - 如何在mysql中获取从开始到结束日期的周记录

Question

我有一个名为 weight 的表，字段是 ID、WEIGHT、CREATED ON。我在 PHP 变量中也有 START 日期和 END 日期。现在我想获得从开始日期到结束日期的一周明智记录。
结果应该是这样的:

WEEK | WEIGHT | CREATED ON
-----+--------+-----------
1    |   50   | 2012-02-01
1    |   50   | 2012-02-03
1    |   50   | 2012-02-05
1    |   50   | 2012-02-07
2    |   50   | 2012-02-08
2    |   50   | 2012-02-10
2    |   50   | 2012-02-14
3    |   50   | 2012-02-15
3    |   50   | 2012-02-17
3    |   50   | 2012-02-17

如何实现？

希望对你有帮助

SELECT ID, weigth, created_on, WEEK(created_on) week
FROM weight
WHERE created_on BETWEEN start_date AND end_date
ORDER BY week
