DATE DIFFERENCE - ORACLE 9I - SQL QUERY
I want to calculate TOTAL SUSPENDED time by a CALL_ID - excluding Bank Holidays (business hours only  - 8am to 6pm) - IS THIS POSSIBLE?? -  example table....
CALL_ID          TYPE                                         DATESTAMP
001                  SUSPENDED                             01/01/2007 08:15:15
001                  UNSUSPENDED                        06/01/2007 15:45:12
001                  SUSPENDED                             04/03/2007 12:14:16
001                  UNSUSPENDED                        04/03/2007 16:45:10
002                  SUSPENDED                            04/05/2006 17:12:36
