Basically truncate is a DDL and Delete is DML. You can use
delete to remove rows depending on certain criteria and it
generated redo logs and can be rolled back before you
commit the transaction, Where as the truncate is used to
remove all the data in the table. Once you execute this
command u can not rollback this transaction.and commit is
not required for the truncate statement
