解决：sqlalchemy.exc.ObjectNotExecutableError: Not an executable object: ‘select 1‘

这个程序是用来测试的，你肯定是这么写的？

with app.app_context():

    with db.engine.connect() as conn:

        rs = conn.execute("select 1")

        print(rs.fetchone())

接下来我们需要对上面代码进行修改，如下所示：

from sqlalchemy import text

with app.app_context():

1.     with db.engine.connect() as conn:
2.         rs = conn.execute(text("select 1"))
3.         print(rs.fetchone())
