What Are The Methods There In Save Exceptions In Oracle Now, Let's call p3: SQL> BEGIN 2 DBMS_OUTPUT.put_line ('calling p3'); 3 p3; 4 END; 5 / BEGIN * ERROR at line 1: ORA-06502: PL/SQL: numeric or value error ORA-06512: at "HR.P1", statementN; EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.put_line (SQLCODE); END; When I execute the block, Oracle Database will try to assign the value 100 to l_number. The function DBMS_UTILITY.FORMAT_ERROR_BACKTRACE is a great improvement to PL/SQL and adds a much needed functionality.
