Question

When I do for example DATEPART(mm, GETDATE()) I get the result of the month being “8” for August. If i did the same thing in December I would get “12”. Those are two different length results.

Is there a way to get the DATEPART results to always be a fixed length? So that for example the months would show up as 08 or 12. And days would be 05 and 30.

More Details:

I’m using a derived column transformation in SSIS to take a server datestamp, and remove all the formatting (spaces, colons, dashes, etc) in order to use it as part of a Primary Key.

My forumula that currently works is below, however it results in variable lenght results which is not ideal. I would like to get all results to be the same lenght.

((DT_STR,4,1252)DATEPART("yyyy",createDate)) + ((DT_STR,2,1252)DATEPART("mm",createDate)) + ((DT_STR,2,1252)DATEPART("dd",createDate)) + ((DT_STR,2,1252)DATEPART("hh",createDate)) + ((DT_STR,2,1252)DATEPART("mi",createDate)) + ((DT_STR,2,1252)DATEPART("ss",createDate)) + ((DT_STR,2,1252)DATEPART("ms",createDate))

Input looks like this:

9/11/2008 8:50:47:300 PM

Results look like:

20089112050473

Results should look like:

20080911205047300

Answer 1

SELECT RIGHT(100+DATEPART(mm, GETDATE()),2)

EDIT based on new info
– to get your timestamp to a fixed string of numbers:

SELECT REPLACE(REPLACE(REPLACE(REPLACE(CONVERT(varchar(23), GETDATE(), 121),'-',''),':',''),' ',''),'.','')
