To answer this question, you need to understand the differences between the commands DROP, DELETE, CASCADE, and TRUNCATE in the context of deleting data from a table.

Let's go through each option to understand why it is correct or incorrect:

Option A) DROP - The DROP command is used to delete an entire table from the database. It not only deletes the data but also removes the table structure and all associated objects. However, it is not the correct command for deleting data from a table without writing to the rollback segment.

Option B) DELETE - The DELETE command is used to delete specific rows from a table based on a given condition. It is commonly used to selectively remove data from a table. However, when using the DELETE command, the deleted data is written to the rollback segment for potential rollback operations.

Option C) CASCADE - The CASCADE keyword is used in conjunction with other commands, such as DROP or ALTER, to specify that the action should be cascaded to dependent objects. It is not a command for deleting data from a table without writing to the rollback segment.

Option D) TRUNCATE - The TRUNCATE command is used to remove all data from a table. It is a fast and efficient way to delete data because it does not generate any rollback information and does not write to the rollback segment. TRUNCATE is the correct command for deleting all data from a table without writing to the rollback segment.

Therefore, the correct answer is D) TRUNCATE. This option is correct because the TRUNCATE command will delete all data from a table without writing to the rollback segment.

To determine the answer, let's break down the given statement and understand how it works:

The statement NEXT_DAY(sysdate, 'MONDAY') returns the date of the next occurrence of the day specified, which in this case is 'MONDAY'.

So, when we execute the statement SELECT to_char(NEXT_DAY(sysdate, 'MONDAY'), 'DD-MON-RR') FROM dual;, it will return the date of the next Monday.

Given that today is Monday, 10 July 2000, the next Monday will be on 17 July 2000.

Therefore, the correct answer is E) 17-JUL-00.

To answer this question, you need to understand the key combinations used to start or end analog recording mode. Let's go through each option to understand why it is correct or incorrect:

Option A) Shift+F3 - This option is incorrect because Shift+F3 is not the key combination used to start or end analog recording mode.

Option B) Shift+F10 - This option is incorrect because Shift+F10 is not the key combination used to start or end analog recording mode.

Option C) Shift+Alt+F3 - This option is correct because Shift+Alt+F3 is the key combination used to start or end analog recording mode.

Option D) CTRL+Shift+F3 - This option is incorrect because CTRL+Shift+F3 is not the key combination used to start or end analog recording mode.

The correct answer is C. Shift+Alt+F3. This option is correct because it is the key combination used to start or end analog recording mode.
