greetings,
i've been using mysql, SA ORM (scoped_session) with cherrypy and all

() workarounds. hence, i want to move everything to SA using the

i wanted to give the adjacency pattern a try in the context of a dog
pedigree database and used

the requirement at hand is to be abe to

you need to use sessions and mappers (not raw SQL expression engine),

Hi,
My code is like that:
try:

rec = SomeModel()
rec.some_val = some_val

hello,
i need to generate a unique number from a table based on the primary
key. i used to lock
the table (with write) and got what i needed. working with the ORM,
though, it seems that
session.add(object) functions just as well. at the time of the
session.add(), the primary key assigned to the
the
data should be considered as utf-8. I'm not sure what version of
MySQL you're on or how older versions of that might get in the way.

SA (0.5.0rc1) keeps returning utf hex in stead of utf-8 and in the
process driving me batty. all the mysql setup is fine, the chars look
good and are umlauting to goethe's delight. moreover, insert and
