how to use data step to calculate summary group by multiple sub groups?

[julie2]

Hi,

How can I replace following PROC SQL code using data step code?

PROC SQL;

select division, category, sum(salary) as total_salary from tbl_salary

group by division, category;

quit;

Thanks!

Julia,

It takes a lot less code with proc sql but, since you asked, I think that the following will do the same thing.  I added an extra field, namely employee_id (emp_id) to indicate that you would have to drop any additional fields if you want the output to be the same.

proc sort data=tbl_salary;

  by division category;

run;

data divsalary;

  set tbl_salary (drop=em_id);

  by division category;

  if first.category then total_salary =0;

  total_salary+salary;

  if last.category then output;

run;

proc print data=divsalary;

run;
