PLS-00420: can't call builtin routines remotely
Cause: An attempt was made to call a built-in PL/SQL function remotely, which is not allowed. For example, the code might look like: my_sqlerrm := SQLERRM@newyork; or INSERT INTO emp VALUES (my_empno, STANDARD.RTRIM@newyork(my_ename), ...);
Action: Always call built-in functions locally; never specify a database link.
