Convert date to YYYYMM format

I want to select value = 201301

select getdate(), cast(datepart(year, getdate()) as varchar(4))+cast(datepart(MONTH, getdate()) as varchar(2))

it returns 20131

what is the normal way to do this?

SELECT CONVERT(nvarchar(6), GETDATE(), 112)

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')

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.

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).

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

SELECT FORMAT(GETDATE(),'yyyyMM') as 'YYYYMM'

this is simple format

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

It's month 1, so you're getting an expected value. you'll have to zeropad the month (1 -> 01), as per this answer: How do I convert an int to a zero padded string in T-SQL?
