Hi

I would like to create a time range dimention based on a numerical value.


so I have a column in my fact table that represents the number of years and I would like the dimention to group the clumns to say <1 year, 1-2 years, 3-5 years, 6-10 years, etc

is the only way to do this to create another table with a number field and a group field (as below)?


Year Group

0 <1 year

1 1-2 years

2 1-2 years

3 3-5 years

4 3-5 years

5 3-5 years

6 6-10 years

thanks in advance

No. You could add a computed column for this. I recommend it be a persisted computed column to make it faster.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

I recommend a table that is then turned into a dimension. It will give you more flexibility to add/change things.
