Final answer:
It is incorrect to say that data from a dropped table can be retrieved unless the database system has a recycle bin or flashback feature, and this must be enabled beforehand.
Step-by-step explanation:
The assertion that data contained in a dropped table can be retrieved if the DROP option was not used in the DROP TABLE command is not accurate. When a DROP TABLE command is executed in a database management system, the table and all associated data are permanently deleted. However, some database systems offer a feature called a recycle bin or flashback technology that can be used to recover tables if they are dropped. Nevertheless, this feature must be enabled before the table is dropped, and it may have limitations and requirements for the recovery of data.
Without such features, the only way to recover data from a dropped table would be through a backup and restore procedure. In practice, it's critical to regularly back up databases to prevent data loss from operations such as the DROP TABLE command. Additionally, transactions logs can sometimes be used to recover data up to a certain point before the table was dropped, but this process can be complex and time-sensitive. Otherwise, restoration from backups or transaction logs is the only method to recover data after a DROP TABLE command.
