Dear Jackson,
The tuple in radius tables are there in the attached file.
Now the following things are to be done:
1. Select a tuple and subsequent tuple and find the timespan between the
datetime of first and the subsequent tuple. if the timespan is greater than the
duration given in the subsequent tuple then update the subsequent tuple with
duration set to the timespan between the first selected tuple and subsequent
tuple:
Consider the following tuples
first tuple:
uname=penguin
logdate=06/12/1999
logtime=11:00:00AM
duration=1 Hrs
rest can be left as such
subsequent tuple
uname=penguin
logdate=06/12/1999
logtime=12:00:00 PM
duration=2 Hrs
Then in the subsequent tuple the duration is wrong this data is taken from a
external source now want to validate it by applying the above condition so the
duration in the second tuple should be set to
uname=penquin
logdate=06/12/1999
logtime=12:00:00 PM
duration=1 Hrs.
Now can you tell me how can i achieve this in postgresql. I am new to
postgresql.
Thanks a lot for your prompt reply.
Regards,
Vicky
