After creating many Class::DBI modules which access Oracle tables I have come to create a module which attempts to access a view and it fails. Module:-

package SDU::DBI_MaxSeqTotPorts;
use strict;
use base 'SDU::DBI';
# SDU_DBI is based on Class::DBI::Oracle
__PACKAGE__->set_up_table('MAX_SEQ_TOT_PORTS');
__PACKAGE__->columns(Primary => 'ID');
__PACKAGE__->columns(Others => qw/CUSTOMER SWITCH_NAME SEQUENCE PORTS/
+);
1;

View:-

CREATE OR REPLACE VIEW sdu.max_seq_tot_ports (
   id,
   customer,
   switch_name,
   sequence,
   ports )
AS
SELECT a.ID, b.CUSTOMER, b.SWITCH_NAME, b.SEQUENCE, SUM(b.COUNT_X)
FROM  SDU_SWITCHES a , SDP_QUERY_RESULTS b
WHERE a.SWITCH_NAME = b.SWITCH_NAME
AND a.CUSTOMER = b.CUSTOMER
AND (b.SWITCH_NAME, b.SEQUENCE) IN
(
  SELECT SWITCH_NAME, MAX(SEQUENCE)
  FROM  SDP_QUERY_RESULTS
  GROUP BY SWITCH_NAME
)
GROUP BY a.ID, b.CUSTOMER, b.SWITCH_NAME, b.SEQUENCE
/

Error:-

The "MAX_SEQ_TOT_PORTS" table has no primary key at /opt/ar/scripts/sd

Using Class::DBI - 0.94, Class::DBI::Oracle 0.51 Any one had this issue?
