[appengine-java] Re: Selecting more than 1000 rows ?
You'll need to add an index property to your entity and specify this index in your query.

1000 is a hard limitation on every query. So if you have 5000 entitties and use range 999-1500 you will get only one record. The only way is to iterate through entities using JDO extend. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

You can use setRange if you want to retrieve entities from a specified offset from the start of the results list, which comes in handy for paging. You can also use it to set a limit, capping the number of returned results. - Jason On Wed, Oct 14, 2009 at 3:22 AM, Sreekanth Raju sraj...@gmail.com wrote: then what is the use of query.setRange() --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
