Oracle SQL Plus Pocket Reference, 2nd Edition

SQL*Plus Format Elements

The COLUMN, ACCEPT, SET NUMBER, TTITLE, BTITLE, REPHEADER, and REPFOOTER commands allow you to control data formats using what is called a format specification. A format specification is a string of characters that tells SQL*Plus exactly how to format a number, date, or text string when it is displayed.

Formatting Numbers

Table 1-3 shows the format elements that may be used when formatting numeric output.
