从两个日期中选择，自动显示连续的行数据

Question

我期望从两个日期中选择，自动显示连续时间行数据。

e.g：

Select * 
from somefunction('2013/5','2019/3');

预期结果：

Year | Month
-----+------
2013 |  5
2013 |  6
..   | ..
2013 | 12
..   | ..
..   | ..
2019 |  1
2019 |  2
2019 |  3

Answer 1

我已经解决了问题，这里提供了解决方案。

declare @dStart datetime = '2013/05/01'
,@dEnd datetime = '2019/03/31';

SELECT year(Dateadd(month,number,@dStart)) as year,month(Dateadd(month,number,@dStart)) as month
FROM master..spt_values
WHERE 
    type = 'P'
    AND number <= DATEDIFF(month, @dStart, @dEnd)
GO

year | month
