Hi,
I've installed SQLalchemy and I've tried to connect to mysql db, and

no convenient way to do that right now, youd have to use a bind
parameter:
select("name=:somebind", somebind=':foo')
to enable what you want to do directly would require the parsing that
locates ':bind' tokens to be more intelligent about quotes, we can add
a ticket for that if you like.

Hello,
for a somewhat more complex query I need to specify the where clause
explicitly when selecting objects of a mapped class. Now how would one
include constants with a colon in such a query?
like:
session().query(myclass).select("name = ':foo'")
Any ideas?

Cheers, Sol.
