I believe in general you need having c.next_contact = max(c.next_contact)
(at least in ANSI SQL) Use having for after the join has occured *Bryan Sayer* Retired Demographer/Statistician /In a world in which you can be anything, *be kind*/ On 12/4/2025 2:55 PM, Rich Shepard wrote:
I want the script to extract only the maximum `next_contact' date and haven't learned how to do this from my reading of web sites. The script: select p.person_nbr, p.company_nbr, c.next_contact from people as p, contacts as c where c.next_contact >= '2025-11-01' group by p.person_nbr, p.company_nbr, c.next_contact order by p.person_nbr, p.company_nbr, max(c.next_contact); returns all contacts rather than only the latest one. Is using a sub-select the proper way? TIA, Rich
