i'm writing a program in perl to populate a database.  the code seems to be the way it should, but when i run it, the script does not create a new table.  it drops the table but doesn't create it.  i get an error message saying table does not exist when it gets to the insert statement.


 #use strict;
         use DBI;
         my $dbh = DBI->connect( 'dbi:Oracle:XE',
                               ) || die "Database connection not made:


my $sql = qq {DROP TABLE CUSTOMER};
$dbh->do ($sql);

my $sql = qq { CREATE TABLE CUSTOMER (
            id INTEGER PRIMARY KEY,
            fname vARCHAR2(30),
            lname VACHAR2(30),
            street VARCHAR2(50),
            city VARCHAR2(30),
            state VARCHAR2(20),
            zip VARCHAR2(10),
            gender VARCHAR2(10)
$dbh->do ($sql);

my $insert_handle = $dbh->prepare_cached('INSERT INTO CUSTOMER (id,

fname,lname, street, city, state, zip, gender) VALUES (?,?,?,?,?,?,?,?) ');
      die "Couldn't prepare queries; aborting" unless defined


my @tuple;
my $index=1;

open(TEST, "custdata_CSV.csv");
while (<TEST>){
      @tuple = split(/,/,$_);
      print "$tuple[0]\n$tuple[1]\n$tuple[2]\n$tuple[3]\n$tuple[4]

You have a typing error near "lname"
=>  lname VACHAR2(30)
should be
=>  lname VARCHAR2(30)
(you forgot an R)

You should be using the strict and warnings pragmas.

Also, you should enable RaiseError on the DB connection.

use strict;
use warnings;
use DBI;

my $dbh = DBI->connect('dbi:Oracle:XE', 'username', 'password',
                       { RaiseError => 1, PrintError => 0 })
            || die "Database connection not made: $DBI::errstr";


Your id field should be auto incremented instead of manually updating the index number.

You should always check the return status of an open call.

open(TEST, '<', "custdata_CSV.csv") || die "Can't open custdata_CSV.csv <$!>";

>> how do you do auto increment in oracle?

I work with mysql but I assume the DBD::Oracle module supports the same syntax as DBD::mysql.

my $sql = qq { CREATE TABLE CUSTOMER (
                                     id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,

I've seen websites that say it can't be done that way in Oracle.  check this out:
