This is explained in the last paragraph of http://www.sqlalchemy.org/docs/sqlexpression.html#executing-multiple-sta tements: """ When executing multiple sets of parameters, each dictionary must have the same set of keys; i.e. you cant have fewer keys in some dictionaries than others. This is because the Insert statement is compiled against the first dictionary in the list, and it's assumed that all subsequent argument dictionaries are compatible with that statement. """ I think a check has been added in 0.6 so that an exception is raised if you don't follow this advice.
