As of I know,we can roll back bothe delete and truncate
statements.but in case of delete statement logging of the
details in the log file takes more time,beacuse it logs the
details row by row in the page.
when it comes to truncate,all the rows will be logged at
the same time.
Please correct me,If I am wrong.
