Transaction Isolation Levels

[Milind Kulkarni]

Hi All,

      Can anyone explain me the difference between transaction isolation
      levels ' ReadCommitted' and 'RepeatableRead':

      It appears to be the same:

     ReadCommitted: Only data that have been committed by a transaction can
     be read by other transactions.
     RepeatableRead: Only data that have been committed by a transaction
     can be read by other transactions, and multiple reads will yield the
     same result as long as the data have not been committed.

   Thanks,
   Milind
