What triggered the Error:
An application made reference to unknown or inaccessible data.What should we do to fix it:
Handle this condition within the application or make appropriate modifications to the application code. NOTE: If the application uses Oracle-mode SQL instead of ANSI-mode SQL, ORA-01403 will be generated instead of ORA-00100.
