Sam, Great! I had no idea DISTINCT ON existed. That made it much simpler. Here's what I used: select distinct on (inventory.charge) coil_id, inventory.charge, heating_coldspot_time_reached from inventory inner join charge on charge.charge = inventory.charge where base_type = '3' and heating_coldspot_time_reached > 0 and inventory.status = 'Done' and inventory.charge >= 1000 order by charge, heating_coldspot_time_reached desc And thanks for the tip about E-mail. I thought that if I hit the Reply button and then changed the subject line, it would be the same as sending a new message to the same destination. In this case, I had to change the destination also, so it looked like a brand new message. I didn't know I was bringing along old baggage behind the scenes. Thanks very much!
