61

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?

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')

    Among all the answers this is easy to understand by just looking at it and also can be modified easily if needed. +1 up – nirav Jul 23 '18 at 07:13

    FYI, the first argument of `FORMAT` is a `date` type, so passing in a `varchar` or `nvarchar` will result in an error like, `Argument data type nvarchar is invalid for argument 1 of format function.` – openwonk Oct 04 '19 at 18:42
  • Also, no matter how long the other solutions take, FORMAT with take at least 26 times longer even when other solutions seem to be much more complex. – Jeff Moden Dec 06 '22 at 19:43

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

To obtain a format modification for such type of value, in case u wanted to apply it for the whole column, u had to do the following:

SELECT TO_DATE(variable-which-format-u-wanna-change, 'YYYYMM') FROM table;

However, I don't know how to use the output to add a column u_u

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?
