I have this table that have the volume for each product:

PRODUCT	VOLUME
NK	200
CN	180
CY	220

And another table the have the percentage share for each country:

REGION	SHARE
AUSTRALIA	0.45
CHINA	0.55

I want this output, the propotion the volume of each product by each country

PRODUCT	REGION	VOLUME
NK	AUSTRALIA	90
NK	CHINA	110
CN	AUSTRALIA	81
CN	CHINA	99
CY	AUSTRALIA	99
CY	CHINA	121

How do I achieve this in PROC SQL? I have simplified the table, in real there are more columns.

You're looking for a cross join or natural join.

You can use a.*, b.* to specify keeping all columns in each table.

proc sql;
create table want as
select a.*, b.*, a.volume*b.share as volume_proportion
from table1 as a
CROSS JOIN table2 as b
order by a.product, b.region;
quit;
