thanks again, AM. no need to have this extra trouble, as I just asking
this as a matter of curiosity. it thought it was something rather simple

Hi,
It looks like session.merge() converts String type primary key to its
lower-case equivalent before processing.

Hi all,
I solved this before, but i took me half a day and a lot of guessing and i
forgot.
If i add (sometimes calculated) columns to a query and i want to set the
names manually (via label()?), how do i do
I solved it (again):

say you have the expression Person.name (Person is SQLA class) to use in a
query, to have a label show up under that name in the resulting

thanks, Michael,
we crossed responses; i thought it was something like that, but there are
some gotchas (at least for me; see above).

I think the following:
q = session.query(A, B).filter(A.b_id == B.id)
print q

thanks Ladislav!
yup, that one gives me what i want, but i was kinda working on plain
select([col1, col2], from_obj=) function :)
but nevermind bothering, its just part of a building process that's i'm
writing in SA (instead of making them by hand), people are used to do
selects like
well ... just bumped at Bundle. it does the job :)

Hi Michael,
OK, that's why.
Below are the stack traces. They are not the same for A.b and A_b. If i use
other labels this error does not happen.

Hi:
It seems that the argument to query.limit must be a number. However,
NULL (which I imagine could be passed by the null() construct or as a
string) and ALL (which, I suppose could be text(ALL) or
literal(ALL) or just the string ALL) are perfectly acceptable
values on PostgreSQL.
Is there some
LIMIT NULL and LIMIT ALL per the PG docs at
http://www.postgresql.org/docs/9.0/static/queries-limit.html are the same as
omitting the number.These would appear to be syntactical helpers that you
wouldn't really need when working with a select() construct (unless you're
trying to get at
Redshift needs LIMIT ALL to avoid attempting an optimization which
causes it to crash.
Note that OFFSET 0 is the same as omitting OFFSET, but it acts as an
optimization fence. This, I suppose, is a similar thing.

the int() catch here on limit/offset is something we added due to user report
which raised the issue that it's a security hazard, back when we used to render
the given value directly in the SQL without using a bound parameter. We fixed
both that it allowed non-int values as well as that it
15 matches
