Retriving records with the date and time stamp

Question

I need to get all the records that were update between 08:36:06 AM and 8:36:09 AM on the12/15/2009
I am using this query it is giving me the right numbers (I think) because this condition GURMAIL_CPLN_CODE = 'UGAP', I would like something more
precise using the date and time stamp with the dates
12/15/2009 08:36:06 AM
12/15/2009 08:36:07 AM
12/15/2009 08:36:08 AM
12/15/2009 08:36:09 AM
select * from GURMAIL
where
PERMAIL_CPLN_CODE = 'UGAP'
AND TO_CHAR(PERMAIL_ACTIVITY_DATE,'MM/DD/YYYYHH24:MI:SS AM') >= '12/15/2009 08:36%'Thank you

Answer 1

Yes, but HH24 and AM cannot be used together:
SQL> select to_date('12/15/2009 08:36:06 am', 'mm/dd/yyyy hh24:mi:ss am') from dual;
select to_date('12/15/2009 08:36:06 am', 'mm/dd/yyyy hh24:mi:ss am') from dual
ERRORE alla riga 1:
ORA-01818: 'HH24' impedisce l'uso dell'indicatore meridianoUse this:
select *
from   gurmail
where  permail_cpln_code = 'UGAP'
AND    permail_activity_date between to_date('12/15/2009 08:36:06', 'mm/dd/yyyy hh24:mi:ss')
                                and  to_date('12/15/2009 08:36:09', 'mm/dd/yyyy hh24:mi:ss')or this:
select *
from   gurmail
where  permail_cpln_code = 'UGAP'
AND    permail_activity_date between to_date('12/15/2009 08:36:06 AM', 'mm/dd/yyyy hh:mi:ss am')
                                and  to_date('12/15/2009 08:36:09 AM', 'mm/dd/yyyy hh:mi:ss am')Max
