insert overwrite/into 或者 create table as 的 SQL 才可以从 Table 创建 DataFrame,否则没法创建。
只能全部读取从 pandas DataFrame 创建本地 PyODPS DataFrame

insert overwrite/into 或者 create table as 的SQL是会把数据写到表里面的吧,这样岂不是还是需要临时表
from aliyun-odps-python-sdk.
是需要创建,但是这个操作实际上没有什么 overhead
本来 select 语句就会有落地数据,insert 之类的无非是 meta 有条记录而已。
