Hi all, I have been using db4o in my project,i have to search result and arrange in Descending order according to particular filed. I follow below code, but am getting null value.
public List<Recipe> getRecipiesByString(String searchValue) { List<Recipe> list=null; Query query=db().query(); query.constrain(Recipe.class); Constraint constraint= query.descend("_title").constrain(searchValue).contains(); query.descend("_description").constrain(searchValue).contains().or(constraint); query.descend("_rating").orderDescending(); list= query.execute(); return list; } I have Class Recipe there, "_title" & "_description" are string fields and "_rating" is double type field. when i try to do in descending order with the fields "_rating", it has been giving null value, and after comment of this line query.descend("_rating").orderDescending(); then value is coming properly. what is solution to get result in Desceding order according to "_rating". -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
