how to simplify what i'm doing (AS the solution?)

i need to do create reports that perform queries where the results are
percentages of total count divided by counts based on different
subquery where values.
a la ...
select 100 * (totalCount/ (select count where columnA value is x) as
partialCount1) as perc1,
100 * (totalCount/ (select count where columnA value is y) as
partialCount2) as perc2
etc
from myTable where (..bunch of where stuff..)
I have simplified the above example just for brevity here.
So, I hate these kinds of nested queries - and they get incredibly
complex to read. I could break them up into longer scripts to simplify
- but I am wondering if there's another way.
The data I am using is from a warehouse on SQL 2005. I have very little
experience with warehouses - and know little about analysis services
and OLAP.
My question is whether it is possible to use Analysis services to
create new tables that make this data far easier to query? That's the
path I am considering venturing down, but I don't want to hit a dead
end... and need just to know if this makes sense. That is to use
Analysis services to crunch out some new tables from the tables I am
using which would have the results neatly packaged in a table or 2 that
is fast and simple to query. Is that the idea of AS?
thx for helping a learner here. let me know if i am making enough sense
in the question.
Hi
This looks like you are trying to do a pivot, in which case the best
solutions will be at the front end although with SQL 2005 you have the new
pivot function, check out the topic "Using PIVOT and UNPIVOT " in books
online.
