Why not call a function that make an insert as insert into dummy values
('Start',now()) ?

Hi,
I want to find the time taken by this process ...retrieving data from
oracle database using java and copying that to postgres using copy.
So I need something like this
Start_Time|java testCode ...|psql -c copy dummy from stdin with delimiter
',' null 'NULL' test| End_time
so that the output is like this
Start_time 2009-02-19 11:30:15
End_time 2009-02-19 11:40:15
This should give me the time this process started and the time it ended. Is
that possible?
Thanks
Sharmila
