Hello Graeme,

DESCRIBE is a command that has meaning only to Oracle's interactive
query utility called "SQL*Plus".

To get information about a database from a Perl script, you can use
the data dictionary tables. You might find the following article
helpful:

http://www.oreillynet.com/pub/a/network/2002/10/28/data_dictionary.html

You can also got to otn.oracle.com, dig for the Oracle documentation,
and then for the "Oracle Database Reference" manual, and in that you
will find comprehensive descriptions of all the data dictionary
tables and columns.

Best regards,
