There are somethink wrong:
- wrong begin (i use the dollar-quoting-style)
- no 'begin'
- missing ';'
- you want to get a result but defined the function as void
I have rewritten this for you, i hope, this is what you expected:
create function izitest() returns int as $$
begin
if 1 <> 1 then
return 1;
else
return 2;
end if;
end;
$$ language 'plpgsql';
