Re: UPDATE Table 1 with JOIN Table 2
> create a table that only includes the earliest entry for each individual.
Identified by id?
This identifies the desired rows:
select id,min(date_of_entry) as first
from tbl
group by id;
To make the new table ...
drop table if exists newtbl;
create table newtbl
select a.col1, a.col2, ... -- all desired columns
from tbl a
join (
select id,min(date_of_entry) as first
from tbl
group by id
) b on a.id=b.id and a.date_of_entry=b.first;
