Comparing timestamp

Question

hi i need to compare to timestamp with precition of microsecond in other words:
select * from any_table where
to_timestamp(DT_INSERIMENTO, 'dd/mm/yyyy HH24:MI:SS,FF6') = to_timestamp('27/10/2011 16:18:36,346560','dd/mm/yyyy HH24:MI:SSxFF9')
and the resulting set has just the row that match exactely the condition,
so i do not want in the result set row that have in the column dt_inserimento a value different than
27/10/2011 16:18:36,346560
for example row that have
27/10/2011 16:18:36,444450
how i can accomplish this?
thanks

Answer 1

If that's the case what about something like this?
SELECT *
FROM   any_table
WHERE  dt_inserimento = TO_TIMESTAMP('27/10/2011 16:18:36.346560','dd/mm/yyyy HH24:MI:SSxFF9')If dt_inserimento is already a TIMESTAMP you don't need to use the TO_TIMESTAMP function.
