I am getting the same error when trying to parse the SQL with SQL::Parser. However, it work with DBD::SQLite, for example: 
#!/usr/bin/perl
use warnings;
use strict;

use DBI;
use DBD::SQLite;

my $sql = DBI->connect('dbi:SQLite:dbname=1.db', q(), q());

$sql->do('create table TABLENAME        (type varchar, name varchar)')
+;
$sql->do(q(insert into TABLENAME values ('MASTER',     'm1')));
$sql->do(q(insert into TABLENAME values ('MASTER',     'Data1')));
$sql->do(q(insert into TABLENAME values ('SLAVE',      's1')));

my $sth = $sql->prepare(q(select T.Name from TABLENAME T
                          where T.Type = 'MASTER'
                              and not exists (select 1 from TABLENAME 
+T2
                                              where T2.Name = T.Name
                                                  and T2.Name like 'Da
+ta%')));
$sth->execute;
my $aref = $sth->fetchall_arrayref;
print "@$_\n" for @$aref;
