Thanks :-) That worked fine. >plpy.execute returns dictionary, and you need a list. You may try this: > >CREATE FUNCTION "test_python_setof"() >RETURNS SETOF text AS ' > records=plpy.execute("SELECT name FROM interface"); > return [ (r["name"]) for r in records] >' LANGUAGE 'plpythonu'; > > > Then I tried to do some changes and try to return a SETOF type: CREATE TYPE "test_python_t" AS ( name varchar(50) ); CREATE FUNCTION "test_python_setof"() RETURNS SETOF test_python_t AS ' records=plpy.execute("SELECT name FROM interface"); return [ (r["name"]) for r in records] ' LANGUAGE 'plpythonu'; And I'm getting ERROR: tuple return types are not supported yet. On my production database server I'm using PostgreSQL 7.4 and using language plpgsql I'm returning some SETOF type without problems. Is this a feature that's missing on this version or I'm I doing something wrong on code? If is a feature missing, is already implemented on some version afterwards? Best regards, Luís Sousa
