I got that the obvious way is just writing the string query, i.e.
query.filter(col IN SELECT col FROM some_table)

Hi,
i need to add several functions to all dialects that i'll plan to use
in order to be fully database-independent.
Does anybody have tips how to achieve this?

we'll be adding a feature for this soon. here is a non-public way to do
it for now which will work throughout 0.5:
from sqlalchemy.sql.expression import ClauseElement
class year(ClauseElement):
__visit_name__ = 'year'
def __init__(self, value):
self.value = value

is there an easy way to represent an interval tree table in sqlAlchemy
Interval Tree is very common way to represent tree.
with right, left, level indices, node, leaf (left - right = 1) ?

there's no restriction using the SQL expression language. The ORM can do
it too,
This is my ORM class definition:
#=
class User(Base):
__tablename__ = 'b_taa_user'
user_id = Column(Integer, primary_key=True, autoincrement=True,
nullable=False) # 用户ID
user_name = Column(Unicode(255), unique=True, nullable=False,
server_default=) # 用户名称
