Hi!
I'm playing with refcursor, but I'm not successful. I defined follwing
function:
CREATE OR REPLACE FUNCTION stat() RETURNS refcursor AS '
DECLARE
ref refcursor;
BEGIN
OPEN ref FOR
SELECT * FROM tagebuch;
RETURN ref;
END;
' LANGUAGE 'plpgsql';
Trying to see some results gives me:
sport=# select stat();
ERROR: fmgr_info: function 16556: cache lookup failed
sport=# select version();
version
---------------------------------------------------------------
PostgreSQL 7.2.1 on i686-pc-linux-gnu, compiled by GCC 2.95.4
(1 row)
sport=# select * from tagebuch;
...
This works fine. I receive the same error when I try to call stat() from Python with pyPgSQL-DBI adaptor. What am I
doingwrong (PostgreSQL runs on a Debian/Woody box)?
Regards,
Oliver
