What is difference between TRUNCATE & DELETE
Answer posted by Scott on 2005-05-25 18:30:04: TRUNCATE is a DDL command and cannot be rolled back. All of the memory space is released back to the server. DELETE is a DML command and can be rolled back. Both commands accomplish identical tasks (removing all data from a table), but TRUNCATE is much faster.
