您可以使用来告知
TextClause（由产生
text()）列类型
.columns()：
from sqlalchemy import inspectsession = Session()stmt = text('select * from t').columns(*inspect(T).columns)t = session.query(T).from_statement(stmt).first()assert type(t.attrs) == dict, repr(t.attrs)或者，对于SQLAlchemy
<0.9，使用typemap参数：
from sqlalchemy import inspectsession = Session()typemap = {c.name: c.type for c in inspect(T).columns}stmt = text('select * from t', typemap=typemap)t = session.query(T).from_statement(stmt).first()assert type(t.attrs) == dict, repr(t.attrs)
