Re: returns setof rec... simple exampe doesn't work - Mailing list pgsql-general

I’ll answer my own question...

select * from myfunc();

(dumb, dumb, dumb....)

-dave

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
