How to change date format from yyyy-mm-dd to yyyymm?

Question

Please help with converting my date code to give output in YYYYMM format.

select convert (date,DATEADD(YEAR, DATEDIFF(YEAR,0,GETDATE()) + 1, -1))  as lastDayOfPrevYear
SELECT DATEFROMPARTS ( DATEPART(yyyy, GETDATE()) - 1, 1, 1 ) as firstDayOfPrevYear
SELECT DATEFROMPARTS(YEAR(GETDATE()), 1, 1) as firstDayOfCurrentYear

Answer 1

Dates do not have a format, but you can create a string or even an int as yyyymm

Example

Select convert(varchar(6),getdate(),112)

Answer 2

Simply use the FORMAT function like this

SELECT
    MyDate = GETDATE(),
    mmddyyyy = FORMAT(GETDATE(),'MMddyyyy'),
    YYYYMM = FORMAT(GETDATE(),'yyyyMM')

Answer 3

SELECT CONVERT(varchar,GETDATE(),112); the answer is "201907"
