Not that I am aware of. Bear in mind that not all content providers will be using a SQL database as the place of data storage. Since the contacts content provider does appear to use SQLite, rather than iterating over your contacts, though, you could try the IN syntax in the WHERE-style constraint: [WHERE] person_id IN (...) where ... is a comma-delimited set of values, or possibly even a sub-select to get the IDs of the contacts to update. http://sqlite.org/lang_expr.html -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Looking for Android opportunities? http://wiki.andmob.org/hado --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
