The data extraction facility allows you to extract data from a database by redirecting the output of a SELECT statement from the standard interface to one or more disk files or named pipes. Several database options listed in Table 2-1 (TEMP_EXTRACT_...) are used to control this feature. For details on the use of these options, see “Data extraction options” in Chapter 7, “Moving Data In and Out of Databases” in the System Administration Guide: Volume 1.
