Truncate is a DDL operation that removes all rows from a table, while delete is a DML operation that removes specific rows.

• Truncate is faster than delete as it doesn't generate any undo logs or triggers.

• Truncate cannot be rolled back, while delete can be rolled back using the transaction log.

• Truncate resets the identity of the table, while delete doesn't.

• Truncate doesn't fire delete triggers, while delete does.

• Truncate is non-logged operation, while delete is logged operation...read more
