oops, .filter(database.c.person_id == person_id) fixed the problem.
Thanks!

Hello,
In this query I get extra (unexpected) "databases" table name in FROM clause
q = dbsession.query(
meter_readings.c.reading,
database.c.service_id
). \
select_from(
database.outerjoin(meter_readings, true())
).filter(Database.person_id == person_id)

Thank you, Mike, but I need something like this
type_coerce(
Database.meters_readings[
func.generate_subscripts(Database.meters_readings, 1)
], type_=ARRAY(Text)
)[1]
Database.meters_readings is two-dimensional array like [ ['1', '2', '3'], ['4',
'5', '6'] ], so

Hello,
I'm writing a satellite passage scheduler that has a database persistence
layer to store the scheduled passages.
The DB schema is organized as follows:
- A table storing the satellites (using NORAD No as Primary Key)
- A table storing the ground stations where to compute the passages of
Thank you Mike!
So suppose I have an a Manager object *manager* and I wanted to promote
that to Engineer:
# Modify the persisted data of the manager object in the db directly.
session = object_session(manager)
session.execute(manager.__table__.update() \
.where(m

Hello,
I try to rewrite "meters_readings[generate_subscripts(meters_readings, 1)][1]"
from plain sql query that works
with sqlalchemy and
Database.meters_readings[func.generate_subscripts(Database.meters_readings,
1)][1] doesn't work

Hi there,
I am writing a custom dialect and sqlalchemy currently generates a
statement like this:
```
SELECT count(some_table.id) AS count_1, some_table.x + some_table.y AS lx
FROM some_table GROUP BY some_table.x + some_table.y ORDER BY lx
```
As you can see it uses the alias lx in ORDER BY b
I sorted this problem out and, as you predicted, it turned out to be layers
upon layers of problems. If
you do not mind having a quick look at how I resolved this, I would really
appreciate some feedback
and a second opinion...
I actually missed the main problem initially. It had to do with the
I have this error when i passed to python3
in other side all the modules worked fine with python2 so i don't know why
