I would add that data analysis queries that have multiple level of aggregation analysis can be complicated also. For example, in a table of racer times find the average time for each team while only counting teams whom at least have greater than four team members and produce an ordered list displaying the ranking for each team according to their average time. -- Regards, Richard Broersma Jr. Visit the Los Angles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug
