Describe a function
desc function [name];
Create a function
create function [name] as '[package.ClassName]' using '[resource.jar]';

说明
MaxCompute UDFs are managed through SQL-style statements issued from the odpscmd command-line client. The resource (jar, py file, archive) must be uploaded first with `add jar` / `add py` / `add archive` before a function can reference it. Function names are unique per project. Users need write permission on the project to create functions and delete permission to drop them.
