DESCRIBE is a SQL*Plus command. It is not part of the Oracle SQL language. You need to either query the data dictionary views directly, or use the statement handle attributes like NAME, PRECISION, TYPE, etc. to get this information.

I believe a describe statement is Oracle DDL, but I still failed for both of the ways that I know of to execute sql. There must be something


that I am not considering.

#!/usr/local/bin/perl
#script to demonstate execution failure
use strict;
use warnings;

use DBI;
use DBD::Oracle;

my $username='';
my $password='';
my $dbsid='';
my $cont;

eval {
$cont = DBI->connect('dbi:Oracle:' . lc($dbsid), $username, $password,
{
RaiseError => 1,
AutoCommit => 0,
ora_session_mode => 0
}
);
};


die "problem" if ($@);

my $sth;

#1
eval {
       $sth = $cont->prepare("desc user_tables");
};

if ($@) {
print "$DBI::errstr";
#exit;
} else {
eval {
$sth->execute;
};
if ($@) {
print "$DBI::errstr";
#exit;
}
}


#2
eval {
       $cont->do("desc user_tables");
};

if ($@) {
       print "$DBI::errstr";
       #exit;
}
