use DBI;
use strict;

my $driver = "mysql"; 
my $database = "TESTDB";
my $dsn = "DBI:$driver:database=$database";
my $userid = "testuser";
my $password = "test123";

my $dbh = DBI->connect($dsn, $userid, $password ) or die $DBI::errstr;

Simple INSERT query

my $sth = $dbh->prepare("INSERT INTO TEST_TABLE
                       (FIRST_NAME, LAST_NAME, SEX, AGE, INCOME )
                         values
                       ('john', 'poul', 'M', 30, 13000)");
$sth->execute() or die $DBI::errstr;
$sth->finish();

BIND INSERT query

my $sth = $dbh->prepare("SELECT FIRST_NAME, LAST_NAME
                        FROM TEST_TABLE 
                        WHERE AGE > 20");
$sth->execute() or die $DBI::errstr;
print "Number of rows found :" + $sth->rows;
while (my @row = $sth->fetchrow_array()) {
   my ($first_name, $last_name ) = @row;
   print "First Name = $first_name, Last Name = $last_name\n";
}
$sth->finish();
