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

CREATE FUNCTION fn_GetMonthlyDates
(
  @ProcessDate smalldatetime
)
RETURNS @LOAN TABLE 
(
 ProcessDate    smalldatetime
)
AS
BEGIN
    DECLARE 
        @Today DATE= @ProcessDate,
        @StartOfMonth DATE ,
        @EndOfMonth DATE;

    DECLARE @DateList TABLE (DateLabel VARCHAR(10) );
    SET @EndOfMonth = EOMONTH(@Today);
    SET @StartOfMonth = DATEFROMPARTS(YEAR(@Today), MONTH(@Today), 1);

    WHILE @StartOfMonth <= @EndOfMonth
    BEGIN
       INSERT  INTO @DateList
       VALUES  (@StartOfMonth );
       SET @StartOfMonth = DATEADD(DAY, 1, @StartOfMonth);
    END;

    INSERT INTO @LOAN(ProcessDate)
    SELECT  DateLabel
    FROM    @DateList; 

RETURN
END
