Hi all. I've encountered an SQL problem that I think is beyond my skills...
I've got a table full of records relating to events (phone calls, in this case) and I need to find the largest number of events (calls) occurring at the same time. The table had a start timestamp and a duration field which contains the length of the call in seconds. I need to find out how many concurrent calls I supported, at peek volume. Can this be done in SQL? Or do I need to write a perl script? Thank you, Mike. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
