To answer this question, you need to understand the concept of the DUAL table in Oracle.
Option A) EMP - This option is incorrect because the EMP table is not specifically designed for arithmetic calculations on values defined within the SELECT statement.
Option B) The table containing the column values - This option is incorrect because the question specifically mentions that the values are not pulled from a table column.
Option C) DUAL - This option is correct. The DUAL table is a special table in Oracle that contains only one row and one column. It is often used for performing arithmetic calculations on values defined within the SELECT statement. The DUAL table can be used to select constant values, perform calculations, or test expressions without the need for an actual table.
Option D) An Oracle-defined table - This option is incorrect because although Oracle provides various predefined tables, the DUAL table is specifically designed for this purpose.
The correct answer is C) DUAL. This option is correct because the DUAL table is commonly used for performing arithmetic calculations on values defined within the SELECT statement.
