So I can set it to a default value, such as 'N/A' - something similar to
the MSSQL function ISNULL that I can use in the class definition.

I'm basically looking for something I can add to the backref or ForeignKey
definition for the case that the value of provider_id is None.

I have the following models:
class LabResult(Model):
__tablename__ = 'cp_svc_lab_result'
id = Column(Integer, primary_key=True, autoincrement=True)
test_code = Column(String(255))
test_code_system = Column(String(255))
test_name = Column(String(255))
test_name_orig = Column(String(255))
proc_name
g like that. check the docs.

I have the following two models:
Class Encounter(Model):
__tablename__ = 'cp_service'
id = Column(Integer, primary_key=True, autoincrement=True)
master_service_id = Column(String(255))
admission_datetime = Column(DateTime)
admission_provider_id = Column(String(255))
Works perfectly!
Thanks!

I am iteratively building a complex query. For one step, I have

I would like to simply just replace the value in Clinical.string value such

this as

I am trying to do a bulk insert of a large list of dictionaries of the form:

Dear all,
How can I expand the output to show ALL query parameters.
For example, I have the following:
2015-07-09 09:51:09,478 INFO sqlalchemy.engine.base.Engine (['test_code'],
['13457-7'], ['result_value_num'], '160', '160', ['1970-01-01'],
['blood_pressure'], ['blood_pressure'] ...
Hi all,
I have the following union query:
q1 = db.session.query(label('sid',distinct(left.c.patient_sid)))
q2 = db.session.query(label('sid',distinct(right.c.patient_sid)))
query = q1.union_all(q2)
Which works just fine.
And I have the following query to which I would like to join this:
For the record, this should have a '==' for the join condition: q =
intersect.join(query_select, query_select.c.sid == intersect.c.sid)

Weird, I had tried using the subquery() method earlier, but it didn't work.
Not sure why, but now it is returning the desired query object. (I guess
stepping away from this for a few hours was a good idea, eh?!)

I really dig use of the column operator for constructing queries, but have
been unsuccessful with using this when the argument is between. I read
somewhere that Column.op(var) when var = in_ does not work, so I would
assume that this is true with between.
Am I doing something wrong, or is

eval() was definitely not doing what I expected. Thanks for the tip about
getattr(), and thanks for helping get my head screwed on right!

Yeah, there's no reason to touch eval -- and a lot of reasons not to.
I have a situation where I can have an arbitrary number of subqueries that
need to be joined on the last step, except if the number of queries, n, is
1.
For example, for n = 1, suppose I have a complex query set to the variable
A[1]
The final submitted query would then look like:
-bit python now, so this makes sense.

The first place I’d look in this case would be your freetds.conf, you
