summing across units, vertically, using sql

[geneshackman]

Hi all. This should be simple, but I can't quite get it to work, and what I found on web searching hasn't helped exactly, perhaps because i don't understand sql well enough. Here is part of the data. Each county has population by race/ethnicity. I want to get state population by race/ethnicity, summing across all counties.

Shouldn't this be fairly simple?

CountyCode	Race	Population	County
36000	State Total	58344005	New York State
36001	County Total	915097	Albany
36001	Hispanic or Latino	58094	Albany
36001	NH American Indian or Alaska Native	1370	Albany
36001	NH Asian and Pacific Islander	63194	Albany
36001	NH Black or African American	116750	Albany
36001	NH More than one race	22848	Albany
36001	NH White	652841	Albany
36003	County Total	137788	Allegany
36003	Hispanic or Latino	2401	Allegany
36003	NH American Indian or Alaska Native	295	Allegany
36003	NH Asian and Pacific Islander	1739	Allegany
36003	NH Black or African American	1709	Allegany
36003	NH More than one race	1632	Allegany
36003	NH White	130012	Allegany
36005	County Total	4251645	Bronx
36005	Hispanic or Latino	2390496	Bronx
36005	NH American Indian or Alaska Native	11814	Bronx
36005	NH Asian and Pacific Islander	176974	Bronx
36005	NH Black or African American	1242803	Bronx
36005	NH More than one race	42322	Bronx
36005	NH White	387236	Bronx

Thanks

Just to mention, i tried this so far

proc sql;
create table tempb as
select *, sum(population)
from tempa
group by race
order by race;
quit;

but it returns all the counties, by race, so it's returning the same data. What am i doing wrong?

This is the reason:

select *

As you include all columns, SQL does an automatic remerge (see the NOTE in the log). To avoid this, you must only have results of summary functions and variables included in the GROUP BY in your SELECT.

select race, sum(population)
from tempa
group by race

Thanks very much! That was it.
