Hi I wanted to use some select result several times in pl/pgsql function.
DECLARE test refcursor; x record; BEGIN open test for select... fetch test into x; while found loop ...work... fetch test into x; end loop;
...rewind cursor using move... fetch test...
Neither move backward 10000 in test; nor execute ''move backward 10000 in test''; doesn't work.
In first case I get: ERROR: parser: parse error at or near "$1"... In secod: ERROR: unexpected error -5 in EXECUTE of query... I tried also with "perform" - I got no error, but also no valid result.
What should I do with it? Or maybe is it possible somehow to use cursor in FOR..IN loop?
Regards, Tomasz Myrta
