I need to get a join across about 8 tables to only return rows for the MAX date in one of the tables for all otherwise identical return results. I am trying to get the most recent edit of normalized records that are composed of elements from all the tables. There could be 1 to 100+ successive edits to the normalized/multi table record. The will be approximately 65,000 total records for now, 100,000,000s later. If I make one of the values in the select statement be MAX(the date), does that automatically do grouping on 'the date' or will I only get ONE row total returned? KUDOS, I almost never need to write the postgres group . . . because it just works. It's only using postgres that I ever even read the digest that I receive. Soon I will have to write more to get performance tips. You guys are great on this list and seem to always have answers, Thx.
