After you use the create sequence statement to create a sequence, you can use the NEXTVAL pseudo column to get the next value in the sequence.
<h3 /><h3>How do you create a sequence?</h3>
- You must have the Create any sequence system privilege to create a sequence in another user's schema.
- Specify the schema that will hold the sequence.
- If you leave out schema, Oracle Database will create the sequence in your own schema. Name the sequence that will be created.
- Pseudo-columns allow selection, but you cannot edit, update, or remove their values.
- A pseudo-column is analogous to a function that does not accept any inputs. This section goes over the two pseudo-columns, CURRVAL and NEXTVAL.
- A pseudo column is a "column" that displays a value when a value is selected but is not one of the table's true columns.
- Two examples are SysDate and RowID. It is frequently used in tandem with the DUAL table.
- After you utilize the make sequence statement to make a sequence, you can utilize the NEXTVAL pseudo column to obtain the next value in the sequence.

Answer: I think the answer is B. the compiler will issue an error message indicating that the exception must be caught or declared.
Explanation:
The switch displays this message because the configuration
file and all of its contents was not saved to non-volatile random-access memory
(NVRAM). It is currently only located in RAM. To copy the running configuration
file which, you should use the copy run start command which will copy the
running configuration file to the startup configuration. It will prompt you to
save the start config file.

I'd say cut and paste.
In general and by definition, cut and paste is a way of moving files, selected text or folders to another location. Cut removes and paste inserts. An Item can be removed from its current location and placed into the clipboard by cutting. Paste inserts the item in the current clipboard into the new location. This same concept also works in graphics design. You can cut a paragraph or a segment of text from a manuscript with a blade and paste it into a different part of manuscript
