Hi,
I'm new to app engine and I have a question when I come to this
sentence:"a query will never return more than 1000 enties". If I
execute a query and store the return result in a List, but I don't
detach them, i.e., keep them in the persitent manager. And the entries
in that List is beyond 1000, would it be possible?
For example:
public void updateIndex(int from, int value)
{
PersistenceManager pm = PMF.get().getPersistenceManager();
Query query = pm.newQuery(Article.class);
query.setFilter(String.format("index >= %d", from));
try
{
List<Article> articles = (List<Article>)query.execute();
for(Article article: articles)
{
article.setIndex(article.getIndex() + value);
pm.makePersistent(article);
}
}
finally
{
query.closeAll();
pm.close();
}
}
If the query returns 2000 entries, will it work or not? If not, would
you please recommend me a alternative way?
Thank you very much.
