The DUAL table is a special one-row, one-column table in Oracle that is used to evaluate expressions that do not involve any tables. It is commonly used to request system information or derived values such as the current date and time or to test the syntax of a query. It is also used as a dummy table when a table is required for SQL syntax but not for any actual data. The other choices (NULL, TEMP, and SYS) are not specifically designed for this purpose.
