SAS功能搜索

Question

my data set includes billed amounts & refunds. I'd like to match billed amounts and refunds together when relevant. I have a unique identifier which allows me to see which rows should be added. I've done this before easily enough using R Software but my data set is on SAS.

Can anyone suggest a function in the Query Builder that will allow me to do this & perhaps illustrate how it is best used?

A snip of my data set is below.

Answer 1

Many different possible ways. eg Proc SQL , Proc Means , Proc Summary , Data Step using double DOW. Very easy would be group by in Proc SQL

proc sql;
create table data_want as
  select a.*, sum(a.total) as new_total
    from data_have a
      group by a.UniqueID
    ;
quit;

Regarding the query builder (which will just produce proc sql code):

1. When selecting variables for the query there is a column Summary behind every selected variable. Set this to SUM for the total Variable.
2. You will be asked to choose a GROUP Variable. Select your unique ID here.

Answer 2

proc sort input_data; by 'Unique Identifier' /*In_date*/;
run;

data result;
  set input_data;
  by 'Unique Identifier';
  retain res_total 0;
  if first.'Unique Identifier' then res_total = total;
  res_total + total;
  if last.'Unique Identifier' then output;
run;
