MySQL - 在日期范围内按周分组结果

Question

我有一个users存储TIMESTAMP 的表,当他们的帐户被创建时.我正在尝试编写一个查询,该查询将显示在给定时间段内按周(按周一开始)分组的新用户.导演将进入并选择报告日期范围,因此选择2个变量.他们应该看到显示所有在2个选定变量日期之间注册的新用户的结果,按周(周的周一开始)分组

变量: @StartRangeSelectDate @EndRangeSelectDate

用户表:

| id         | TIMESTAMP
----------------------------------------------
| 1          | 2013-09-02
| 2          | 2013-09-08
| 3          | 2013-09-12
| 4          | 2013-09-27

结果应该是(当选择的开始日期类似于2013-09-01,结束日期是2013-09-29:

| YearWeek         | # of New Users
----------------------------------------------
| 2013 36          | 2
| 2013 37          | 1
| 2013 38          | 0
| 2013 39          | 1

查询以显示日期范围中的新用户总数,但尚未在日期范围内按周分组:

SELECT COUNT(user.id) AS '# of New Users in Date Range'
FROM user 
WHERE user.Inactive = 0
    AND user.TimeStamp BETWEEN @StartRangeSelectDate AND @EndRangeSelectDate;

Answer 1

SELECT yearweek(`TimeStamp`, 1) yw,
       COUNT(id) AS '# of New Users in Date Range'
FROM user 
WHERE Inactive = 0
AND TimeStamp BETWEEN @StartRangeSelectDate AND @EndRangeSelectDate
GROUP BY yw
