Description:

local_file: path of local file, and take this file name as the resource name. Resource name is a unique identifier of a resource.
table_name: table name in ODPS.
[PARTITION (spec)]: when the resource to be added is a partition table, ODPS only supports taking a partition as a resource, not a whole partition table.
alias: specify the resource name. If not added this parameter, the file name is default to be the resource name. Jar and Py resources do not support the fuction.
[comment ‘cmt’]: add comment for resource.
[-f]: if the same name resource exists, to add this parameter will cover the original resource. If this parameter is not added and the same name resource exists, the operation will fail.

Example:

odps@ odps_public_dev>add table sale_detail partition (ds='20150602') as sale.res comment 'sale detail on 20150602' -f;
OK: Resource 'sale.res' have been updated.
