    Just subtract the current month from today's date, then add back your month number. Then use the datename function to give the full name all in 1 line.

    print datename(month,dateadd(month,-month(getdate()) + 9,getdate()))

    To convert month number to month name, try the below

    declare @month smallint = 1
    select DateName(mm,DATEADD(mm,@month - 1,0))

    I think this is the best way to get the month name when you have the month number

    Select DateName( month , DateAdd( month , @MonthNumber , 0 ) - 1 )
    

    Or

    Select DateName( month , DateAdd( month , @MonthNumber , -1 ) )

    You can use the convert functin as below

    CONVERT(VARCHAR(3), DATENAME(MM, GETDATE()), 100)

    You can use the inbuilt CONVERT function

    select CONVERT(varchar(3), Date, 100)  as Month from MyTable.
    

    This will display first 3 characters of month (JAN,FEB etc..)

    you can get the date like this. eg:- Users table

    id name created_at
    1  abc  2017-09-16
    2  xyz  2017-06-10
    

    you can get the monthname like this

    select year(created_at), monthname(created_at) from users;
    

    output

    +-----------+-------------------------------+
    | year(created_at) | monthname(created_at)  |
    +-----------+-------------------------------+
    |      2017        | september              |
    |      2017        | june                   |
