Can one generate HTML reports from SQL*Plus?

One can generate static HTML pages from SQL*Plus (8.1.6 and above) by setting the MARKUP option to HTML ON. This can be done by specifying -MARKUP "HTML ON" from command line, or with the "SET MARKUP HTML ON" command. Look at this example SQL Script:
set markup HTML on
spool index.html
select * from tab;
spool off
set markup HTML off

You can deploy this file on your web site or edit it in an HTML editor (like FrontPage or Dreamweaver). Another good idea is to develop a CSS to present the data more elegantly. One can also embed HTML tags in the select statement to create hyperlinks and add more HTML features.
