【100】求教ORA-00100与ORA-01403的区别

网友回答

【答案】 ORA-00100: no data found
　　Cause: An application made reference to unknown or inaccessible data.
　　Action: 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.
　　Fetching from a cursor after the last row has been retrieved and the ORA-1403 error returned.
