Try a single equals sign, e.g. WHERE c.site = s.siteid
Greg, I'm surprised: that worked! I thought the WHERE clause was looking for equivalency, not an assignment. There's another problem now that will be more difficult to fix. Postgres tells me, 'psql:populate-waterchem.sql:6: ERROR: duplicate key value violates unique constraint "waterchem_pkey"'. But, when I SELECT rows based on the primary key only a single row is returned. I think the most parsimonious solution is to use an awk script to add the stream and basin columns to the chemistry.txt file. That also eliminates having to export the combined table to a text file.
