Hi Tiago,
you mean like this?
SELECT DAY FROM T WHERE DAY < '2007-12-04' ORDER BY DAY DESC LIMITBY 1
I remember this not working on Oracle 7.3.4 (yeah it is somewhat
outdated) because Oracle would sort only AFTER limiting the result
set. So, as a workaround this might not work on all databases.
Thanks, Massimo. Are you sure about the "[db.t.day.max()]"?
I'll also check dal.py if I don't find it in the book. ;-)
@Thadeus: on a Sybase ASE MAX returns one row only. See below.
CREATE TABLE "mt_mytable" (
id int not null,
text varchar
)
insert into "tempdb"."guest"."mt_mytable" (id, text)
print

The issue here is that MAX is not a single record, it could be 5
records with the same date, it could be 5000 records with the same
date.

Can't you sort by day and get the first?
I don't know if max exists.

Now I'm trying to do
SELECT MAX(DAY) FROM T WHERE DAY < '2007-12-04'
and I fail to find an operator for "MAX" in the web2py book. Is it
supported?

PS: The online book is splendid. I like it. Much easier to work with.
Now web2py is a truly "free" application.

db(~db.a.asof.belongs(db()._select(db.b.asof)).select(db.a.asof)
