Sql Solutions
Solution 1 - Sql
SELECT CONVERT(nvarchar(6), GETDATE(), 112)
Solution 2 - Sql
SELECT LEFT(CONVERT(varchar, GetDate(),112),6)

I know it is an old topic, but If your SQL server version is higher than 2012.
There is another simple option can choose, FORMAT function.
SELECT FORMAT(GetDate(),'yyyyMM')
Solution 4 - Sql
Actually, this is the proper way to get what you want, unless you can use MS SQL 2014 (which finally enables custom format strings for date times).
To get yyyymm instead of yyyym, you can use this little trick:
select
right('0000' + cast(datepart(year, getdate()) as varchar(4)), 4)
+ right('00' + cast(datepart(month, getdate()) as varchar(2)), 2)
It's faster and more reliable than gettings parts of convert(..., 112).
Solution 5 - Sql
A more efficient method, that uses integer math rather than strings/varchars, that will result in an int type rather than a string type is:
SELECT YYYYMM = (YEAR(GETDATE()) * 100) + MONTH(GETDATE())
Adds two zeros to the right side of the year and then adds the month to the added two zeros.
Solution 6 - Sql
You can convert your date in many formats, for example :
CONVERT(NVARCHAR(10), DATE_OF_DAY, 103) => 15/09/2016
CONVERT(NVARCHAR(10), DATE_OF_DAY, 3) => 15/09/16
Syntaxe :
CONVERT('TheTypeYouWant', 'TheDateToConvert', 'TheCodeForFormating' * )
- The code is an integer, here 3 is the third formating without century, if you want the century just change the code to 103.
In your case, i've just converted and restrict size by nvarchar(6) like this :
CONVERT(NVARCHAR(6), DATE_OF_DAY, 112) => 201609

Solution 7 - Sql
this is simple format
convert(varchar(6),getdate(),112)
Solution 8 - Sql
SELECT FORMAT(GETDATE(),'yyyyMM') as 'YYYYMM'
Solution 9 - Sql
It's month 1, so you're getting an expected value. you'll have to zeropad the month (1 -> 01), as per this answer: https://stackoverflow.com/questions/309165/how-do-i-convert-an-int-to-a-zero-padded-string-in-t-sql
