One more thing,
I remove the many to many mapper (for ConvPre class and the associated
mapper) and:
- This work fine on sa 0.4.x
- This don't work on sa 0.3.10
Are there any changes relative a this problem in 0.4.x versions ?

Hi all,
trying to figure out how i could add an arbitrary string to an sql.expression.
If have something like this:
s = select([columns])
if cond:
s = s.where(text(cond))
if addtl:
# how to tack addtl to the end of the statement?
# this does not work
s = s +

its the same idea
Thank you for the answer!
Does it have any performance differences between the 3 manners?
Which one could be the fastest if I have a lot of nested joins to do
with other tables?
Thanks

straight SQL constructs without using the ORM are always much

another thing im considering, along the lines of what I mentioned in
