I'm just not getting it:

Want:   select max(id) from table;

attempt (latest):

from sqlalchemy import *
from sqlalchemy.engine import reflection
from sqlalchemy import schema
from sqlalchemy import exc
from psycopg2 import *
import re
import time
import os
targethost = "192.168.181.204"
targetdb = "postgresql://user:pword@"+ targethost +"/whatever"
eng2 = create_engine(targetdb)
con2 = eng2.connect()
meta2 = MetaData()
meta2.reflect(bind=eng2)
insp2 = inspect(eng2)
dst_tab = meta2.tables["tab1"]
q3 = dst_tab.select([func.max(dst_tab.c.id)])
maxphoneid = con2.execute(q3).scalar()


I get: sqlalchemy.exc.ArgumentError: SQL expression object or string 
expected, got object of type <type 'list'> instead

without the brackets in the select call, I get:

sqlalchemy.exc.ProgrammingError: (psycopg2.ProgrammingError) argument of 
WHERE must be type boolean, not type integer
LINE 3: WHERE max(phone.id)

There's gotta be a way! Any ideas?
