Question

I have two data sets. Table1 has just one record. Table2 has many records. I want to combine these so that the variables from Table1 are added to every record in Table2.

I know this can be done with proc sql like this:

proc sql;
 create table3 as
  select *
  from table1, table2;
quit;

I want the same result, but using a data step. What’s the best (elegant, efficient) way to do this?

Answer 1

data table3;
if _n_ = 1 then set table1;
set table2;
run;

That’s the simplest way.
