How to show only one header in sqlplus

When you have to use sqlplus and want to avoid showing table header each n rows returned, you can use the command bellow to show only one header:


set pagesize 0   -- only one header row

Another useful commands:
set colsep ,     -- separate columns with a comma
set trimspool on -- remove trailing blanks
set headsep off  -- this may or may not be useful...depends on your headings.
set linesize X   -- X should be the sum of the column widths
