So I have stored some data in the app-engine database, with new data every 5 seconds.
example dataset: ID - Time - Value 1 - 9/20/2008 16:00:00 - 100 2 - 9/20/2008 16:00:05 - 120 3 - 9/20/2008 16:00:10 - 130 4 - 9/20/2008 16:00:15 - 250 ....... 17278 - 9/21/2008 15:59:60 - 200 17279 - 9/21/2008 15:59:55 - 100 17280 - 9/21/2008 16:00:00 - 220 How do I get just 1000 values back that cover the entire recorded period, so I can put them in a chart? What sort of query should I construct? I imagine it's something like, 'give me every 20th value' -- but how do I express than in a query? Thanks in advance for your kindness and consideration. - s --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
