NEW QUESTION # 228
You execute this command:
TRUNCATE TABIE depts;
Which two are true?

  • A. A ROLLBACK statement can be used to retrieve the deleted data.
  • B. It retains the integrity constraints defined on the table,
  • C. It always retains the space used by the removed rows.
  • D. It retains the indexes defined on the table.
  • E. A FLASHBACK TABLE statement can be used to retrieve the deleted data.
  • F. It drops any triggers defined on the table.

Answer: B,D

Explanation:
When the TRUNCATE TABLE command is used:
* C. It retains the indexes defined on the table. This is true. The TRUNCATE TABLE operation does not drop the indexes on the table; it only removes all rows from the table.
* D. It retains the integrity constraints defined on the table. This is correct. The TRUNCATE TABLE operation does not affect the integrity constraints; it retains them.
Options A, B, E, and F are incorrect:
* A is incorrect because the TRUNCATE TABLE operation cannot be rolled back as it is a DDL operation and not a DML operation like DELETE.
* B is incorrect because TRUNCATE TABLE does not drop any triggers; they remain in place.
* E is incorrect as TRUNCATE TABLE may or may not release the space depending on whether the REUSE STORAGE clause is used.
* F is incorrect because FLASHBACK TABLE cannot be used to retrieve data after a TRUNCATE TABLE operation since it does not generate redo logs that FLASHBACK relies upon.
