Using data from two datasets for an equation.

[preston]

I have multiple different data sets, and I am trying to use two at a time for calculations. For instance:

I have a dataset with approximately 90,000 rows, each row has columns: policy , age, gender, loyalty (years with company), smoker, zip code, accidents, premium.

I have another dataset with 6 rows. each row has columns: accidents, Charge.

What I am trying to do is take the accidents from the first dataset for each row and reference that number of accidents with the same number in the second dataset under the accidents column, and then use what is in the charge column for that many accidents (by row) as a multiplier. 

I have spent a few hours trying different things and haven't really come up with any solutions.

EDIT: I have uploaded a visual I quickly made to make it easier to understand what I am trying to accomplish

This is a lookup, there are quite a few posts on here about the most efficient way. I suggest looking into proc format and a left join.

Here's a paper that lists several other options:

I will look into that and read that link asap. thanks

I'm not having any luck with that info. All I can figure out how to do with a lookup is take an individual policy and perform my desired actions, I need to create a new table with every value from one dataset multiplied by its corresponding value from the other dataset

Hi,

proc sql;
  create table WANT as
  select  A.*,
          B.CHARGE,
          A.ANNUAL_PREMIUM * CHARGE as NEW_PREMIUM
  from    WORK.HAVE A
  left join WORK.ACCIDENTS
  on      A.ACCIDENTS=B.ACCIDENTS;
quit;

Thanks, I'm going to bed now But I will work with this in the morning!
