一种方法是递归CTE：

One method is a recursive CTE:

with cte as (
      select dateadd(day, 1 - day(@startdate), @startdate) as som,
             eomonth(@startdate) as eom
      union all
      select dateadd(month, 1, som), eomonth(dateadd(month, 1, som))
      from cte
      where dateadd(month, 1, som) < @enddate
     )
select *
from cte;

如果要输入月份名称，则可以使用 datename（个月）。。

If you want the name of the month, then you can use datename(month, som).
