Exam 1z0-071 Topic 9 Question 239 Discussion

A: True. TRUNCATE is generally faster than DELETE for removing all rows from a table because TRUNCATE is a DDL (Data Definition Language) operation that minimally logs the action and does not generate rollback information. TRUNCATE drops and re-creates the table, which is much quicker than deleting rows one by one as DELETE does, especially for large tables. Also, TRUNCATE does not fire triggers.
References:
* Oracle documentation specifies that TRUNCATE is faster because it doesn't generate redo logs for each row as DELETE would.
* TRUNCATE cannot be rolled back once executed, since it is a DDL command and does not generate rollback information as DML commands do.
