Hi
Im using DatePart Function for Gjenerating the Quartely and Monthly sales in sql Server 2005 Stored Procedure with Pivot Tables. DatePart(qq,date) as Quarter, DatePart(mm,Date) as Monthly.
I want also to Display the Sales on 4 month Basis and 6 month basis using pivot. Any suggestion on how to come arround this Function since doesnt provide the 4 month or 6 month ??

Use Modulo 4 and Modulo 6 to limit the values to quarterly & every six months. Of course, you can only use June & December for the six month breaks.

For the pivot, I posted something like what you are trying to do a little while ago..

It shouldn't be too hard to switch it around for a quarterly summary too.

Something that I used to use that is just a tabular implementation of Grant's suggestion:

create table Months (MonthNo int, Month4Period int, Month6Period int)

insert into Months

Select 1, 1, 1

Union All Select 2, 1, 1

Union All Select 3, 1, 1

Union All Select 4, 1, 1

Union All Select 5, 2, 1

Union All Select 6, 2, 1

Union All Select 7, 2, 2

Union All Select 8, 2, 2

Union All Select 9, 3, 2

Union All Select 10, 3, 2

Union All Select 11, 3, 2

Union All Select 12, 3, 2

Then you just add:

, (Select Month4Period From Months Where MonthNo=DatePart(mm,Date)) as Month4

, (Select Month6Period From Months Where MonthNo=DatePart(mm,Date)) as Month6

to your query columns.

I'm curious... Why 4 months? That's a third of a year...

That's probabrly why, Jeff. I did some work for an insurance company several years ago and they requested this exact same breakdown: Every 3 Mos, Every 4 Mos and Every 6 Mos, in a year. Some kind of reporting paradigm that they use.

Hmmm.... Wonder why they do that? The 4 month thing, I mean. Is there any advantage?

Heh... I've done the exact same thing... start thinking "Quarters", start writing "4's" 😀

Got me. I was actually doing work for a Claims Adjustment company whose customers were the insurance companies and their only explanation was "That's what our customers want".
