Update Statement With Date Field

Question

I'm trying to run an update statement and I want the date to be updated in the format:
5/4/2010 12:31:54 PM
If I run this query on dual it displays correctly: select to_char(sysdate,'DD/MM/YYYY HH12:MI:SS PM') from dual
If I run this query though on my table I get a 'not a valid month' error.
UPDATE WR_MEASURE_VALUE SET HOST_CORRECTED_VALUE=35,
HOST_CORRECTED_DATE=to_char(sysdate,'DD/MM/YYYY HH12:MI:SS PM') WHERE WR_MEASURE_VALUE_OID= 474066
what am I doing wrong and how can I get my update statement to update the date correctly in the 'DD/MM/YYYY HH12:MI:SS PM' form?
Thanks
Guess all I needed to say was HOST_CORRECTED_DATE= SYSDATE
Thanks anyway

I want the date to be updated in the format: 5/4/2010 12:31:54 PMDate Formats are only of importance when you select/retrieve the dates.
As you already understand, you can use TO_CHAR for that.
If HOST_CORRECTED_DATE is of DATE datatype, then you can simply:
update wr_measure_value
   set host_corrected_value = 35,
       host_corrected_date  = sysdate
where wr_measure_value_oid = 474066;

I see you already found out yourself ;)
