I have to use PGArray fields, but I think this is only available using
SQlalchemy 0.4. Easy_install only installs 0.4 when it detects Python
2.5. Is there some sort of backport available?

You received this message because you are
not sure what easy_install issue youre having (i only run py 2.4 here).

Excuse the newbie question, how does one declare a sef-referencing

from sqlalchemy import Column, TEXT
Column('mytext', TEXT)
or use 'String' without a length qualifier:

I´m not sure if I should ask this here or the Pylons forum:
How does one wrap a query in a transaction when using SAContext? Could
someone post some example code?
Also, I read somewhere that SQL92 defined transactions eliminate the
need to lock tables, is that right?
Thanks
How would would write a query with a BETWEEN?
This does not produce what I want
resultset = select([links, links.c.lft 3, links.c.lft 10]).execute()
I would like all the values lft in table links greater than 3 but
less than 10
I am using PostgreSQL

This does not work either :-(

10) ]).execute()

JSON object holds a list of menu items for my site. What would be the
best way to achieve this?
1. Convert the JSON object to Python code using simplejson, pickle
