Answer 1

Simple fix once you get to the right patch level on 19c.

Because there is only ONE type of macro in 19c, you don't need to quantify which type, eg

SQL> create or replace function f_get_ids(p_user in nvarchar2)
  2  return nvarchar2 sql_macro(table)
  3  as
  4  begin
  5    return q'[select id from table1 where user=p_user]';
  6  end;
  7  /

Warning: Function created with compilation errors.

Function created.

Same as when you asked here as well:-)
