How many rows are you expecting from this join?
(If you're not sure, try SELECT count(*) FROM same-from-and-where-clauses)
My bet is that you've mistyped something leading to an unconstrained
join --- maybe an extra instance of a table, or something. The query
doesn't show anything like that as given:
> SELECT sites.longname, solar.year, solar.doy, solar.solar
> climate.tmax FROM solar, sites, climate WHERE solar.id = sites.id AND
> climate.id = sites.id AND solar.year = 1999;
but you have obviously not copied-and-pasted exactly what you typed.
