Cartesian SQL join.
Data never sleeps
Astounding
PROC Star

Fastest to program?  Fastest to execute?  Fastest to explain how it works?

 

Here's one way:

 

data want;

if _n_=1 then set b;

set a;

run;

 

The full Cartesian product (already suggested) is a short program as well:

 

proc sql;

create table want as select * from a, b;

quit;

 

You can test them on larger data sets and let us know which one is faster.
