Hi all,
Can anyone offer suggestions on how to realise this function....
It is the $1 as the table name that is the problem.
I'm using Version 7.4.5
create or replace function last_scan( varchar, varchar ) returns float as '
declare
result float;
begin
result := value from $1 where parameter = $2 order by dt desc limit 1;
return result;
end;
' LANGUAGE plpgsql;
Thanks
Allan
