Hi,
I understand random() is a volatile function and runs multiple times for
multiple rows returned by a SELECT, however is there a way of getting it to run
multiple times *within* another function call and in the same row. i.e.
something like
select regexp_replace('+1 555 555 555', E'\\d', trunc(random() * 9 +
1)::text,'g');
regexp_replace
----------------
+1 111 111 111
(1 row)
As you can see, it returns the same digit each time. I've tried wrapping a
select around the trunc too.
