Subject: [GENERAL] returns setof rec... simple exampe doesn't work
I’ve googled this one and tried everything (except the correct solution of course) until tears are starting to flow. Please help. Complete example below. 7.4.13 on suse-64 x86
create table mytable (mystring varchar, myreal real);
insert into mytable (mystring,myreal) values ('abc',1.23);
insert into mytable (mystring,myreal) values ('def',4.56);
create type myrec as (mystring varchar, myreal real);
create or replace function myfunc() returns setof myrec as '
declare
crec myrec;
begin
for crec in select * from mytable loop
return next crec;
end loop;
return;
end;
' language 'plpgsql';
stdb=# select myfunc();
ERROR: set-valued function called in context that cannot accept a set
