我想要的是如下

++++++++++++++++++
  1 | 2012-02-01
  1 | 2012-02-03
  1 | 2012-02-05

  4 | 2012-03-01
  4 | 2012-03-03
  4 | 2012-03-05
  4 | 2012-03-07

我试过了

SELECT WEEKDAY(date) AS week, date
FROM myTable
WHERE date BETWEEN start_date AND end_date
ORDER BY week

下面是我得到的

week| date
++++++++++++++++++
  1 | 2012-02-01
  1 | 2012-02-03
  1 | 2012-02-05
  1 | 2012-02-07
  1 | 2012-03-01
  1 | 2012-03-03
  1 | 2012-03-05
  1 | 2012-03-07
  2 | 2012-02-08
  2 | 2012-02-10
  2 | 2012-02-14
  3 | 2012-02-15
  3 | 2012-02-17
  3 | 2012-02-17

这是不正确的，因为 2012-03-01 以后显示为 1，应该是 4...让我知道我错在哪里...

提前致谢!!!

Answer 1

使用 WEEKDAY 使用 WEEKOFYEAR

SELECT WEEKOFYEAR(date) AS week, date
FROM myTable
WHERE date BETWEEN start_date AND end_date
ORDER BY week

更新 This question is the source

SELECT  (WEEK(date, 5) -
        WEEK(DATE_SUB(date, INTERVAL DAYOFMONTH(date) - 1 DAY), 5) + 1) as week, date
    FROM myTable
    WHERE date BETWEEN start_date AND end_date
    ORDER BY week

更新2

SELECT  (WEEK(date, 1) -
        WEEK(DATE_SUB(date, INTERVAL DAYOFMONTH(date) - 1 DAY), 1) + 1) as week, date
    FROM myTable
    WHERE date BETWEEN start_date AND end_date
    ORDER BY week
