Re: [appengine-java] Need help in writing a query
Instead of getting these values with query best option is to store this values when you add new employee.So create one more dataset with fields city, area and employeecount.whenever you add new employee update the count .then you can get the count with simple query select employeecount from newdataset where city==city area==area On Sat, Jun 12, 2010 at 8:05 PM, Vik vik@gmail.com wrote: Hie I have following data set: City, Area emp-name and have to write a query which shows number of employees by city and area.
