call the time function before start and end of the function..
Ex:
call_time("print current time")
insert()
{
------------insert statement here-------
}
call_time("print current Time")

Regards,
Nagaa

Same answer as your previous topic, have a look at LAG function.
I merge the 2.

"when the flag 1 activity start" but when there are several flag=1 then activity starts several times?

You have to post a test case: create table and insert statements.
Also post the result you want with these data.
You also have to read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code and align the columns in result.
Use the "Preview Message" button to verify.

Michel
