Here is a sample script I had sitting in my temp directory -- maybe it will help a bit. (Just make sure to enter "real" values for the constants ORAUSER, ORAPASS, and ORATNS.)

#!/usr/bin/perl -w
use strict;

#-- Use modules
use DBD::Oracle;
use DBI;


#-- Define local constants
use constant TRUE      => 1;
use constant FALSE     => 0;

use constant ORAUSER   => 'my_ora_user';
use constant ORAPASS   => 'secret_password';
use constant ORATNS    => 'ora_db_tns_name';


#-- Define local variables
my $gDBHandle;
my $gSQLCmd;
my $gSQLHandle;

my @gFields;


#-- Initialize local variables
$gSQLCmd = 'SELECT  column_name,     ' .
           '        nullable,        ' .
           '        data_type,       ' .
           '        data_length      ' .
           '   FROM dba_tab_columns  ' .
           '   WHERE owner = ?       ' .
           '     AND table_name = ?  ' .
           '   ORDER BY column_id    ';


#-- Connect to the database
$gDBHandle = DBI->connect
  (
    'dbi:Oracle:' . ORATNS, ORAUSER, ORAPASS,
    {
      AutoCommit  => FALSE,
      PrintError  => FALSE,
      RaiseError  => FALSE,
    }
  ) || die 'Could not connect to Oracle ['.$DBI::errstr.' - '.$DBI::er
+r.']';



#-- Get the data
$gSQLHandle = $gDBHandle->prepare($gSQLCmd) 
  || die 'Error with SQL statement ['.$DBI::errstr.' - '.$DBI::err.']'
+;

$gSQLHandle->execute('SYS','DBA_TABLES') 
  || die 'Error with SQL statement ['.$DBI::errstr.' - '.$DBI::err.']'
+;

while (@gFields = $gSQLHandle->fetchrow_array)
{
  print $gFields[0],"\t",$gFields[1],"\t",$gFields[2],"\t",$gFields[3]
+,"\n";
}


#-- Close the database connection
$gDBHandle->disconnect();


#-- Exit
exit;


#-- End of Example

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
