Hi all,
I'm in trouble with the same problem, but in PHP..
With your solution, I cannot be totally sure that last
inserted raw was mine...
Because I'm on a web page, it could be that, as soon
as I've inserted my record, another one do an
insertion, so I would get the wrong ID...
does transactions resolve this, in Psql???
I thought to solve it with a similiar solution,
working in transactions inserting a raw and
immedialtly after read from DB last raw, but who
assure me that all will go right??
If I was on a server app., I (and you, if it is your
case) would insert a timestamp, and then I'd select
from table where timestamp = mysavedtime;
But in my case there could be two or more equals
timestamp, cause there's not only one application
working with DB...
I'm still reading, searching, trying...
ciao
