Reporting Tools in Oracle's SQL*Plus: COLUMN : COLUMN « SQL PLUS Session Environment « Oracle PL/SQL Tutorial

Change the way a column displays by using the COLUMN command

The COLUMN command has the following syntax:

COLUMN column-name FORMAT format-specification

column-name is the column heading you wish to format.

The format-specification uses a's for text and 9's for numbers, like this:

an - text format for a field width of n

9n - numeric format with no decimals for a field width of numbers of size n
