Hi,
can anybody explain to me why the update statement on conn1 below is
not rolled back? conn2 should be in autocommit mode, but why does it
commit transactions of conn1?
Any help could be appreciated.
Thanks
Ralph

from sqlalchemy import *
engine = create_engine('sqlite:///s.db', echo=True)
conn0 = engine.connect()
conn1 = engine.connect()
conn2 = engine.connect()
conn0.execute('create table atesttable (id int, name varchar(20))')
conn0.execute("insert into atesttable (id, name) values (1, 'otto')")
conn0.execute("insert into atesttable (id, name) values (2, 'gustav')")
tr = conn1.begin()
conn1.execute("update atesttable set name='ottox28' where id=1")
conn2.execute("update atesttable set name='gustavXX' where id=2")
tr.rollback()
assert conn0.execute("select name from atesttable where
id=1").fetchone()[0] == 'otto' # <--- this fails!!
