You are grouping by count_value which means that you are asking the system to return a row for each different count_value.
John, I didn't realize this.
So if you remove the f.count_value from the select statement (not the sum(f.count_value)) - and you remove f.count_value from the group_by and order_by statements - you should get what you want
Aha. I thought I had to select f.count_value in order to obtain sum(f.count_value); it's been a long time since I needed to do something like this.
Something like \copy (select f.stream_tribs, sum(f.count_value), i.common_name, i.sci_name from fish_counts as f, itis as i where f.stream_tribs like '%Nehalem River%' group by f.stream_tribs, i.common_name, i.sci_name order by f.stream_tribs, i.common_name, i.sci_name) to '/home/rshepard/projects/oregon/mohler_sand/data/fish/fishes.dat';
Thanks very much! Rich
