Get All Dates of Given Month and Year in SQL Server

Question

I want to get all dates by declaring month and year in SQL server.

Can anyone please share easy lines of SQL code to get it.

For example:

Answer 1

Same approach as t-clausen, but a more compact:

Declare @year int = 2017, @month int = 11;
WITH numbers
as
(
    Select 1 as value
    UNion ALL
    Select value + 1 from numbers
    where value + 1 <= Day(EOMONTH(datefromparts(@year,@month,1)))
)
SELECT datefromparts(@year,@month,numbers.value) Datum FROM numbers
