Hi guys - I'm having a problem getting my head around some sql - using MySQL. I have a table with rows containing datetime, id, reading
for example - and I'm trying to create a view which contains the latest readings for all ids - what is the sql to achieve this?? select max(datetime), id, reading group by id; appeared to work - it gave me the latest datetimes for all ids, but the readings did not correspond to the datetimet!!! Anyone offer any help?? -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
