Usage
.. code:: python
import os
from odps import ODPS
Make sure environment variable CLOUD_ACCESS_KEY_ID already set to Access Key ID of user
while environment variable CLOUD_ACCESS_KEY_SECRET set to Access Key Secret of user.
Not recommended to hardcode Access Key ID or Access Key Secret in your code.
o = ODPS(
os.getenv('CLOUD_ACCESS_KEY_ID'),
os.getenv('CLOUD_ACCESS_KEY_SECRET'),
project='your-project',
endpoint='your-endpoint',
)
dual = o.get_table('dual')
dual.name
'dual'
dual.table_schema
odps.Schema {
c_int_a bigint
c_int_b bigint
c_double_a double
c_double_b double
c_string_a string
c_string_b string
c_bool_a boolean
c_bool_b boolean
c_datetime_a datetime
c_datetime_b datetime
}
dual.creation_time
datetime.datetime(2014, 6, 6, 13, 28, 24)
dual.is_virtual_view
False
dual.size
448
dual.table_schema.columns
[<column c_int_a, type bigint>,
<column c_int_b, type bigint>,
<column c_double_a, type double>,
<column c_double_b, type double>,
<column c_string_a, type string>,
<column c_string_b, type string>,
<column c_bool_a, type boolean>,
