Answer 1

SELECT DateName(M, DateAdd(M, @MONTHNUMBER, -1))

Answer 2

SELECT DATENAME(month, GETDATE()) AS 'Month Name'

Answer 3

In some locales like Hebrew, there are leap months dependant upon the year so to avoid errors in such locales you might consider the following solution:

SELECT DATENAME(month, STR(YEAR(GETDATE()), 4) + REPLACE(STR(@month, 2), ' ', '0') + '01')     

Answer 4

This one worked for me:

@MetricMonthNumber (some number)

SELECT 
(DateName( month , DateAdd( month , @MetricMonthNumber - 1 , '1900-01-01' ) )) AS MetricMonthName
FROM TableName

From a post above from @leoinfo and @Valentino Vranken. Just did a quick select and it works.

Starting with SQL Server 2012, you can use FORMAT and DATEFROMPARTS to solve this problem. (If you want month names from other cultures, change: en-US)

select FORMAT(DATEFROMPARTS(1900, @month_num, 1), 'MMMM', 'en-US')

If you want a three-letter month:

select FORMAT(DATEFROMPARTS(1900, @month_num, 1), 'MMM', 'en-US')

If you really want to, you can create a function for this:

CREATE FUNCTION fn_month_num_to_name
(
    @month_num tinyint
)
RETURNS varchar(20)
AS
BEGIN
    RETURN FORMAT(DATEFROMPARTS(1900, @month_num, 1), 'MMMM', 'en-US')
END

Answer 6

select monthname(curdate());

OR

select monthname('2013-12-12');
