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

Here is a query:

DECLARE @ReportDate VARCHAR(20)='2019-02-10'

DECLARE @LastDay INT =DAY(EOMONTH(@ReportDate))

DECLARE @DayStart INT=01

CREATE TABLE #TEMPMonth ([MDay] VARCHAR(20))

WHILE @LastDay>=@DayStart

BEGIN
    
INSERT INTO #TEMPMonth 
    
SELECT CAST(CAST(YEAR(@ReportDate)AS VARCHAR)+'-'+CAST(MONTH(@ReportDate)AS VARCHAR)+'-'+CAST(@DayStart AS VARCHAR) AS DATE)
    SET @DayStart+=1

END

SELECT * FROM #TEMPMonth

DROP TABLE #TEMPMonth
