All those query.select arguments go in a orm.query.QueryContext()
do see its __init__ for which arg has what default.

I am defining my result list the following way:
result = queryobject.select(mytable.c.columnname == columnname, limit
= maxResults, offset = 0)
maxResults is the number of records I want returned. In case I want
all the records, I am setting maxResults as -1. However, this is not

not sure what kind of key error youre getting back, but the issue
probably relates either to the lack of a "schema" argument or
improper permissions on one or both tables.

I wondered if it was possible to manage users inside postgres with the
help of SQLAlchemy. But I guess Postgres users are special objects and
not just rows in a table. I tried to do this, but it did not work.

Is it possible to create indexes using a function using sqlalchemy and
postgresql?
Something like: create index idx on table (lower(table.field))

I'm having some connection problems with a TG application using

Unless there's any objections, I think it's time to make pyodbc the
preferred access method for MSSQL.
Currently the MSSQL module checks for DBAPI interfaces in this order if one
isn't specified explicitly:
adodbapi
pymssql
pyodbc
I'd like to change it to the exact opposite:
pyodbc
It sounds like its getting to be time to make pyodbc the preferred DBAPI
interface for MSSQL. I'll start a new thread to see if there's any
objections.

Is there a way I can update the documentation for the MS-SQL backend
to suggest using the PyODBC drivers instead of the adodbapi and the
pymssql drivers?

Hi,
Have a go using pyodbc instead of adodbapi. An easy way to force SA to

Oops - fingers are faster than my brain. Here's the snippet from the
second attempt at creating a Table using autoload, and it succeeds.
---
In [10]: tbl = Table('sysdtssteplog', meta, autoload=True)
In [11]: [c.name for c in tbl.columns]
Out[11]:
['stepexecutionid',
'lineagefull',
'stepname
I'm getting some pretty strange behavior when connecting to SQL
Server.
My code is pretty straight forward, just create an engine, create
metadata, introspect on a table...

db = create_engine('mssql://./msdb')
meta = BoundMetaData(db)
tbl = Table('sysdtssteplog', meta,

Hi,
Try mssql://./some_db_name instead, that certainly doesn't cause a 10s delay
for me.

Ach my sqlserver instance seems to just take a long time and I'm
too impatient.
create_engine('mssql://localhost/some_db_name') takes 10 seconds for
some reason, but it does work.
