I assume since you are using SEQUENCE.NEXTVAL, that this is an Oracle environment, so maybe this will help a bit. (Please note, this is not "good" code, but it was quick. *Smiles*)

use strict;

use dbi;
use dbd::oracle;


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

use constant ORA_USER => 'myschema';
use constant ORA_PASS => 'sesame';
use constant ORA_TNS  => 'tst00';

use constant ERR_OK   => 0;


#-- Define variables
my $mDBHandle;
my $mSQLInsertHandle;
my $mSQLSelectHandle;

my $mSQLInsert = <<'EOSQL';
INSERT INTO test (val, name)
  VALUES (test_seq.nextval,?)
EOSQL

my $mSQLSelect = <<'EOSQL';
SELECT val, name
  FROM test
EOSQL

my @mTuple;


#-- Connect to the database
$mDBHandle = DBI->connect
  (
    'dbi:Oracle:' . ORA_TNS,
    ORA_USER,
    ORA_PASS,
    {
      AutoCommit => FALSE,
      PrintError => FALSE,
      RaiseError => FALSE,
    }
  ) || die $DBI::errstr.' - '.$DBI::err;


#-- Prepare the SQL statements
$mSQLInsertHandle = $mDBHandle->prepare($mSQLInsert) || die $DBI::errs
+tr.' - '.$DBI::err;
$mSQLSelectHandle = $mDBHandle->prepare($mSQLSelect) || die $DBI::errs
+tr.' - '.$DBI::err;


#-- Display records
$mSQLSelectHandle->execute() || die $DBI::errstr.' - '.$DBI::err;
print "Val\tName\n";
print "---\t----\n";
while (@mTuple = $mSQLSelectHandle->fetchrow_array)
{
  print $mTuple[0],"\t",$mTuple[1],"\n";
}
print "\n\n";


#-- Execute the SQL insert statements
$mSQLInsertHandle->execute('test1') || die $DBI::errstr.' - '.$DBI::er
+r;
$mSQLInsertHandle->execute('test2') || die $DBI::errstr.' - '.$DBI::er
+r;


#-- Commit the inserts
$mDBHandle->commit();


#-- Display records
$mSQLSelectHandle->execute() || die $DBI::errstr.' - '.$DBI::err;
print "Val\tName\n";
print "---\t----\n";
while (@mTuple = $mSQLSelectHandle->fetchrow_array)
{
  print $mTuple[0],"\t",$mTuple[1],"\n";
}
print "\n\n";


#-- Disconnect from the database
$mDBHandle->disconnect();


#-- Exit
exit(ERR_OK);


#-- End of Script
