problem with my function
Okay:
I must be missing something vital; I thought my function
was working properly the other day, but now I can't
seem to figure out how I broke it.
[snip code]
drop function t_fastfunc(integer);
create function t_fastfunc(integer)
returns interger
as '
declare nCnt integer;
begin
select count (*) into nCnt
from t_stage_member;
if nCnt < 1500000 then
RAISE EXCEPTION ''Number of records is more than 1.5M'';
return nCnt;
end if;
end;
' language 'plpgsql';
[/snip code]
When I try to create it, I get the following error:
[error]
DROP
psql:./function_cnt.sql:18: NOTICE: ProcedureCreate: return type 'interger'
is only a shell
CREATE
[/error]
Question: What exactly is it tryiing to tell me about not returning a value?
And could someone explain what it means by 'only a shell'?
Thanks!

It is a spelling mistake you are trying to return an interger instead of
an integer.
Also should the line with the IF statement not read
IF nCnt > 1500000 THEN
RAISE EXCEPTION
??

Try spelling "integer" correctly.

It's trying to warn you that you are getting into deep waters. When you
create a function that's declared to return a previously-unheard-of type
name, the system will take it, on the possibility that you are trying to
create the input function for a type you are about to declare. So
there's an entry made in pg_type ... but it's only a "shell" not a
completed type, and you can't do anything else with it until you declare
the type properly.

--yeah ... Darren already told me to clean out
my eye sockets regarding that ... i swear i'm going
to set VI to use ispell each and every time
i do stunts like this ...
