By the way; with another query (but still using exists and case) I get this error: TypeError: self_group() takes exactly 2 arguments (1 given) /usr/local/lib/python2.5/site-packages/sqlalchemy/sql/expression.py, line 2411: (_literal_as_binds(c).self_group(), _literal_as_binds(r)) for (c, r) in whens It is probable that this query is broken, too. Or it may be a bug in SQLAlchemy. If required, I can try to write a minimal example that reproduces the problem.
