SQL为每个月周期创建重复的客户

我需要创建一个表,它是每个日期段的客户组的结果。他们没有任何关系。

所以我有36个月,10个客户。 作为输出,我想要的是一个表,每个客户有36个月的时间,这意味着我应该有360行和两列。

-- CREATE A TABLE of DATES - will produce 36 rows x 1 col
DECLARE @StartDate DATE = '20210701',
        @EndDate   DATE = '20240630';

WITH cte
     AS (SELECT @StartDate AS myDate
         UNION ALL
         SELECT Dateadd(month, 1, mydate) AS myDate
         FROM   cte
         WHERE  Dateadd(month, 1, mydate) <= @EndDate),
     dates
     AS (SELECT Eomonth(mydate) mydate
         FROM   cte),
     activities

     AS (SELECT 'whatever' as Whatever)


SELECT 
       mydate 
FROM   dates

获取客户名单。

-- this will produce 1 column of 10 rows. 
select CustomerName from Customers where Region =3; 

我需要的最终结果

如何在SQL Server v11上执行此操作?
