How To Use DBMS_UTILITY.FORMAT_ERROR_BACKTRACE() in Oracle 11G

PACKAGE :-

CREATE OR replace PACKAGE Test_Format_Error

IS

  PROCEDURE main;

CREATE OR replace PACKAGE BODY Test_Format_Error

IS

 A Number:=5;
 B Number:=0;
 C Number;

  BEGIN

     C:=A/B;
     Dbms_Output.Put_Line('The Output is: '||C);

  EXCEPTION

    WHEN OTHERS THEN

              Dbms_Output.Put_Line('Exception is: '||'  '||DBMS_UTILITY.FORMAT_ERROR_BACKTRACE());

  END;

END Test_Format_Error;

/

Show Errors;

/

   Begin

      Test_Format_Error.main;

  

   End;

Output: -
