Hi
Is there any way to create nested function?
oracle to postgres migration required super function variable reference into nested function without nested function parameter
Oracle sample:
-------------------------------
create or replace function f1(n number) return number
is
vs number:=1;
function nf1(m number) return number is
begin
return vs + m + n;
end;
begin
return nf1(2);
end;
/
run:
--------
SQL> select f1(9) from dual;
F1(9)
----------
12
PostgreSQL's pl/pgsql langauge doesn't grok closures. You are welcome to write "f1" in a language that does. Perl and Python are built-in and many others are available. I assume at least one of them can do this.
