An interesting question:
I've got table as follows where the variables are as follows:
ID GROUP1 GROUP2 TYPE1 YEAR COUNT AMOUNT
where ID is a primary key.
I wish to create a table where the ID PK is dropped and where only the variables GROUP1 GROUP2 TYPE1 YEAR COUNT
AMOUNT appear but where COUNT AMOUNT consist of the sum over the categorical variables (GROUP1 GROUP2 TYPE1 YEAR).
In this case, for every combination of the values of each categorical variables, I have the sum of COUNT and the sum of AMOUNT.
Any idea how to go about with this??
Thank you!!
proc sql;
create table want as
select GROUP1 ,GROUP2 ,TYPE1, YEAR,
sum( COUNT), sum( AMOUNT)
from have
group by GROUP1 ,GROUP2 ,TYPE1, YEAR;
quit;
Few quick rules that can help:
*Grouping variables go in group by statement.
*All other variables need to be an aggregate function.
*Items appearing in select are either from group by ( not required) or an aggregation

There's exceptions to these rules in SAS SQL but working from this will help you avoid issues.
