Question

I need some help with this query:

update MSG_TRACE set MSG_SENT_STATUS = 'INIT',ERROR_CODE = 0,RETRY_COUNT = 0 where MSG_RECEIVED_TIME >= '16-01-2012 00:00:00,000000' and OPER_TXN_ID like 'CAP%' and MSG_SENT_STATUS in ('FAILED','ERROR');

It gives me this error: ORA-01843: not a valid month

The MSG_RECEIVED_TIME is in the format DD/MM/YYYY HH:MM:SS.mmmmmm
like 16/01/2012 02:46:34.729643 PM

thank you very much in advance

Answer 1

The milliseconds part means it is not a date. You need to cast to a timestamp such as:

select to_timestamp('16-01-2012 00:00:00,000000','dd-mm-yyyy hh24:mi:ss,FF')
from dual

If you need it to be a date format then you can cast it further:

select to_date(
         to_char(
           to_timestamp('16-01-2012 00:00:00,000000'
                       ,'dd-mm-yyyy hh24:mi:ss,FF')
          ,'dd-mm-yyyy hh24:mi:ss')
        ,'dd-mm-yyyy hh24:mi:ss')
  from dual
