I used the abv query and got the number of days. NOw I want to find the number of hours in the total duration.
I tried by multiplying the answer from the query with 24 but it showed me errors. I was not able to correct it. If any one could help me it would be great.
TIA

What is the error you are receiving?

When I run the query against the data set provided, the result is 61, and I'm able to multiply it by 24 without any problem.

Here you go...

Select ((DATEDIFF(day,b.startDate,b.Endadate) +1) - (DATEDIFF(wk,b.StartDate,b.Endadate)*2)

- (CASE WHen DATENAME(dw,b.startdate)='SUNDAY' THen 1 else 0 end)

- (CASE when DATENAME(dw,b.endadate)='SATURDAY' then 1 else 0 end)) * 24

oops thats a bit stupid one. I didnt check the brackets properly.

Actually I am trying to design a query that would allocate the number of hours per month based on the available days in a month.

Say In june there are 15 days so in the result of 1484 some hrs be allocated. IN that way

Anyways thanks

At this point, my recommendation would be to build a Calendar or Date table. If you have problems finding a good one on Google or Yahoo (or whatever your favorite search engines are), c'mon back and we'll help you get started. But give it a look-see on your own, first. 😀
