RichJackson,

here is some info that might be of help to you.

Placeholders and Bind Values
========================
Some drivers support placeholders and bind values. Placeholders, also called parameter markers, are used to indicate values in a database statement that will be  supplied later, before the prepared statement is executed.

For example, an application might use the following to insert a row of data into the SALES table:

       INSERT INTO sales (product_code, qty, price) VALUES (?, ?, ?)

or the following, to select the description for a product:

       SELECT description FROM products WHERE product_code = ?

The ? characters are the placeholders.  The association of actual values with placeholders is known as binding, and the values are referred to as bind values.

This is how you would use bind in your PERL program

#!/usr/local/bin/perl5

############################
# File  : db_insert.pl
# Desc  : This script inserts records into the database.
############################

use DBI;

##  Output Buffer off
$|++;

print "Content-type: text/html\n\n";

##  This is the main program
my $dbname = 'database_name';  ##  DB instance name
my $dbuser = 'username';   ##  DB username
my $dbpass = 'password';   ##  DB password

my($status_code,$status_message, @row_ary);

##  Connect to the DB
my($dbh) = DBI->connect("dbi:Oracle:$dbname","$dbuser","$dbpass");

die $DBI::errstr if ( $DBI::errstr);

my $sth = $dbh->prepare(qq{INSERT INTO sales (product_code, qty, price) VALUES (?, ?, ?) }) || die $dbh->errstr;
while (<>){
  chomp;
  my ($product_code, $qty, $price) = split /,/;
  $sth->execute($product_code, $qty, $price) || die $dbh->errstr;
}
$dbh->commit || die $dbh->errstr;

$dbh->disconnect();

Can you please explain in more detail what exactly you are trying to do??

can you post any sample code or SQL statement that you already have??

Please provide as much more detail as you can.

This will help you get a more accurate answer, faster.
