How to write a query in Core Data in iPhone

I have used core data in my apps. My application works fine in online and offline mode . I have doubt about, how to write a query in Core data(Similar SQLite). I wrote a query and used in SQLite. But I want to know about, how to write a query(select, insert, update, etc,.) using core data.

Please guide me and give me some useful links.

I think you cannot write SQL like query (select, insert, update...), rather you have to use NSPredicate objects. Which support such type of operation in its own way.

You should read though Apple's tutorial on Core Data. It goes through the process of making a very simple app that used Core Data. For more complicated queries you will want to make a predicate to restrict the returned values.
