Sql server 2008 插入具有多个Id的日期范围SQL Server 2008

我有一个由

@starDate

和

@EndDate

定义的日期范围。我需要将每个

userId

的日期范围插入表中

例如，我有两个约会

 @StarDate = '2012/05/02' 
 @EndDate = '2012/05/06'  

用户ID：

1-2-3

我想要这些结果

UserID      Date
------------------------        
1     -     2012/05/02  
1      -    2012/05/03  
1       -   2012/05/04  
1       -   2012/05/05  
1       -   2012/05/06  
2       -   2012/05/02  
2       -   2012/05/03  
2       -   2012/05/04  
2       -   2012/05/05  
2       -   2012/05/06  
3       -   2012/05/02  
3       -   2012/05/03  
3       -   2012/05/04  
3       -   2012/05/05  
3       -   2012/05/06

一种方法是使用递归CTE：

with dates as (
      select @StartDate as dte
      union all
      select dateadd(day, 1, @StartDate)
      from dates
      where dateadd(day, 1, @StartDate) <= @EndDate
     ),
     users as (
      select 1 as userid union all select 2 union all select 3
     )
select users.userid, dates.dte
from users cross join dates;

---

注意：这假设开始日期和结束日期变量实际上存储为日期。否则您需要转换它们。

谢谢您修复我的问题！！

with dates as (
      select @StartDate as dte
      union all
      select dateadd(day, 1, @StartDate)
      from dates
      where dateadd(day, 1, @StartDate) <= @EndDate
     ),
     users as (
      select 1 as userid union all select 2 union all select 3
     )
insert into table2(userid, date)
    select users.userid, dates.dte
    from users cross join dates;
