Hi!
I have the Problem, that a function returns a refcursor and I am not able to fetch them. I tried in several ways.
Can you please tell me how to get the cursor data.
Thanks
Chris
PS this is what I have:
create table foo(sirname text, name text);
insert into foo values ('Mueller', 'Marcus');
create function getfoo(char(1)) returns refcursor as
'
declare
ref refcursor;
begin
open ref for select * from foo where sirname like ''%'' || $1 || ''%'';
return ref;
end;
'
LANGUAGE 'plpgsql' VOLATILE;
select * from getfoo('M');
* fetch all in '<unnamed portal 11>';
ERROR: syntax error at or near "'<unnamed portal 11>'" at character 14

Sorry but this didn't help ...
Can not return next ... so I changed the returns as too but same effect as the first function:
drop table foo;
create table foo(sirname text, name text);
insert into foo values ('Mueller', 'Marcus');
drop function getfoo(char(1));
create or replace function getfoo(char(1)) returns setof refcursor as
'
declare
ref refcursor;
begin
open ref for select * from foo where sirname like ''%'' || $1 || ''%'';
return next ref;
end;
'
LANGUAGE 'plpgsql' VOLATILE;
select * from getfoo('M');
-- fetch all in '<unnamed portal 14>';
ERROR: syntax error at or near "'<unnamed portal 14>'" at character 15

I think you need double quotes not single quotes here.

The cursor name is an identifier so use double quotes instead of
single quotes. Also, when using non-holdable cursors you'll need
to be in a transaction block.
begin;
select * from getfoo('M');
fetch all in "<unnamed portal 14>";
commit;
