Question

i have an data step.

   data One;
      set Two;
      /*some code*/
   run;

How to add additional row after last row of new table?

Is it possible to do optimal? (One table may have many rows ~ 100k – 10M)

Thanks! ( it is TOTAL row, yes )

Answer 1

Simply appending the total line to your data set.

data one;
 set Two;
 /* some code * /
run;

data total;
 /* some code or use a proc to generate your totals */
run;

data final;
 set one total;
run;

will append the total row to the dataset one.

If you’re generating summary lines / totals, I’d suggest you look into using proc report. There’s an option to output a dataset that has any summaries, groupings, etc that you create within the report procedure. It can be a really powerful proc.

Something like this SUGI Paper might be useful to get you started.

EDIT: based on the comments

Summary for all:

 proc report data = sashelp.iris out=summary nowd;
   col species sepallength sepalwidth petallength petalwidth;

   rbreak after / summarize;
 run;

Summarize each species group and get total line

 proc report data = sashelp.iris out=summary nowd;
   col species sepallength sepalwidth petallength petalwidth;
   define species / group;
   rbreak after / summarize;
 run;
