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.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is usually not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

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