DELETE vs TRUNCATE vs DROP command

Question

Hi!!

Can someone tell me the difference between these three commands?

Answer 1

After the execution of ‘DELETE’ operation, COMMIT and ROLLBACK statements can be performed to retrieve the lost data.

After the execution of ‘TRUNCATE’ operation, COMMIT, and ROLLBACK statements cannot be performed to retrieve the lost data.

‘DROP’ command is used to drop the table or key like the primary key/foreign key.
