Group by Datepart 30 sec interval?

Hello, im starting with sql and i need to group data in the form of:
datepart("yyyy",date), datepart("mm",date), datepart("dd",date),
datepart(30*s,date). Is any way of getting it?
I know i can get the same in vb passing the interval by parameter, by is it
possible to do it this way?
Thanks a lot!!!
Sorry, for my English
This example takes a datetime and truncates it to 30 second intervals.
By grouping on the expression you should get what you need.
select crdate,
dateadd(ms,- (datepart(ms,crdate) +
((datepart(second,crdate) % 30) * 1000)),
crdate)
from sysobjects

|||Thanks for answering!! As I told before I��m starting so I��m not very good at
this. Would you mind explainig a bit how it works? Cause I do not see it. And
i supposse the ms stands for miliseconds, but vba in excel gives me object
error.
Thanks a lot indeed!!

work. Only problem, is that it does not accept ms in vba.
