Hi, using sqlalchemy 1.0.9 and python 2.7.10.
import sqlalchemy as sa
meta = sa.MetaData()
table = sa.Table('mytable', meta,
sa.Column('foo', sa.String),
sa.Column('bar', sa.String, default='baz'),
)
select = sa.select([table.c.foo])
insert = table.insert().from_select(['foo'], select, include_defaults=True)
print insert
print insert
$ python insert_with_default.py
INSERT INTO mytable (foo, bar) SELECT mytable.foo, :bar AS anon_1
FROM mytable
Traceback (most recent call last):
