why am I getting: sqlalchemy.exc.CompileError: The version of oracle you are using does not support empty inserts.

import_csv.py

import csv
import sys
import logging

import sqlalchemy

def main():
    logging.basicConfig(level=logging.DEBUG, stream=sys.stderr)
    sl = logging.getLogger('sqlalchemy')
    sl.setLevel(logging.DEBUG)
    
    schemaname, tablename, infn, dbaddr = sys.argv[1:5]

    rows = csv.DictReader(open(infn))
    e = sqlalchemy.create_engine(dbaddr)

    # print e.execute('select 1+1 from dual').fetchall()

    md = sqlalchemy.MetaData(e)
    t = sqlalchemy.Table(tablename, md, schema=schemaname, autoload=True)

    conn = e.connect()
    conn.begin()
    for row in rows:
        conn.execute(t.insert(values=row))
    conn.commit()


if __name__ == '__main__':
    main()

because there is no intersection between t.insert().compile().params (lowercase) and rows.fieldnames (uppercase?).
