The TRUNCATE TABLE command in Oracle SQL is used to quickly delete all rows from a table:
* Option A:
* It retains the indexes defined on the table. TRUNCATE does not affect the structure of the table, including its indexes.
* Option D:
* It retains the integrity constraints defined on the table. TRUNCATE does not remove or disable integrity constraints, except for unenforced foreign keys.
Options B, C, E, and F are incorrect because:
* Option B: TRUNCATE does not drop triggers; it only removes all rows.
* Option C: Flashback Table cannot be used after a TRUNCATE because TRUNCATE is a DDL operation that does not generate undo data for flashback.
* Option E: A ROLLBACK cannot be used after a TRUNCATE because TRUNCATE is a DDL command that implicitly commits.
* Option F: TRUNCATE may deallocate the space used by the table, depending on the database version and specific options used with the TRUNCATE command.
