Hi,


 what is the difference between SQL/SQL*PLUS?

  WHAT ARE THE INDEXES?

  WHAT ARE THE COLLECTIONS?
  
  WAHT ARE THE TIGGERS FIRES IN THE TAB  CANVAS?

  WHAT ARE THE GLOBAL  TEMPORARY TABLE WE HAVE?

  WE WILL USE TABLES OR VIEWS IN FORMS?

  IF WE HAVE WHEN_NO_DATAFOUND AND OTHERS WHICH ONE WILL FIRE  
   FIRST?

  CAN WE HAVE FIRST WHEN OTHERS NEXT WHEN NO_DATA_FOUND?

  WHAT WILL HAPPEN IF YOU DONOT CLOSE FILE WHEN YOU OPEN IN     UTL_FILE?

WHAT WILL HAPPEN IF YOU DONOT CLOSE THE CURSOR?
