Hi!

Is there a way to use output parameters with a pl/python fucntion?
I've tried with no luck: if I define out parameters, it says return type
must be record, if I define a record return type, I get an error on
executing that pl/python doesn't support record return type...

My simple test func is:

create or replace function outtest(out i integer, out j text)
 returns boolean as
$BODY$
i = 1
j = 'something'
return True
$BODY$
language plpythonu;

Thanks in advance:
Imre Horvath

first define a custom type, then drop the out parameters.

create type mytype as (
i integer,
j text );

create or replace function outtest()
  returns mytype as
$BODY$
i = 1
j = 'something'
return ( i, j )
$BODY$
language plpythonu;


select * from outtest();
  i |     j
---+-----------
  1 | something
(1 row)

At the moment I think plpython only supports a single OUT param.
