OK here is an example of a function where I had to create a type called
login.
How could I have written this function without having to create a type.
CREATE OR REPLACE FUNCTION "public"."loginbyindidget" (integer) RETURNS
SETOF "public"."login" AS'
declare
iindid alias for $1;
returnRec RECORD;
begin
for returnRec in select tblindividual.indid, tblindividual.title,
tblindividual.firstname, tblindividual.middlename,
tblindividual.lastname, tblindividual.suffix, tblloginname.loginname,
tblloginname.loginnameid, tblloginname.ad,tblloginname.current,
tblloginname.email, tblloginname.note
from tblindividual inner join tblloginname on (tblindividual.indid =
tblloginname.indlink)
where tblloginname.indlink = iindid
order by tblindividual.lastname, tblindividual.firstname,
tblindividual.middlename, tblloginname.loginname
loop
return next returnRec;
end loop;
return;
end;
'LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY INVOKER;
