我可以在 aws redshift python udf 函数中使用选择查询吗

Question

How I can execute a select query in AWS Redshift UDF using plpythonu like oracle function with select into class in function like below.

CREATE OR REPLACE FUNCTION udf(id varchar(50))
RETURNS VARCHAR(50) 
STABLE
AS $$
   result = plpy.execute("SELECT count(*) FROM abc")
   return result
$$ LANGUAGE plpythonu;

when I run above function i got following error.

ERROR: XX000: NameError: global name 'plpy' is not defined. Please look at svl_udf_log for more information

It's available on Postgresql ( https://www.postgresql.org/docs/9.2/static/plpython-database.html ).

At present, Amazon Redshift is not supported.
