Creating All Possible Combinations in a Table Using SAS

Question

I have a table with four variables and i want the table a table with combination of all values. Showing a table with only 2 columns as an example.

NAME    AM         


        

Answer 1

Try

PROC SQL;
CREATE TABLE tbl_out AS
SELECT a.name AS name 
       ,b.amount AS amount
       ,c.count AS count
FROM tbl_in AS a, tbl_in AS b, tbl_in AS c
;
QUIT;

This performs a double self-join and should have the desired effect.
