First, please keep discussions on-list unless otherwise requested.
It's bad etiquette (and a good way to get ignored) to contact someone
directly and off-list :
1) It assumes they have the time to provide you with personal,
2) It assumes no-one else can help.
3) It assumes no-one else (including anyone searching the archives in
the future) could benefit from the assistance given.
Which is nothing whatsoever to do with RRD. That's a simple data problem.
I'm not going to do your coursework for you, but you need to study
the database documentation - and since it's MySQL then you need to
look at the syntax for the "WHERE" clause.
And in fact, you've already given half the answer above - the test
condition is "ID = 4".
Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed
author Gladys Hobson. Novels - poetry - short stories - ideal as
Christmas stocking fillers. Some available as e-books.
