In MongoTalk, there is UpdateOperation. But I can't find how one can do an update with options. http://docs.mongodb.org/manual/reference/method/db.collection.update/ I see Mongo>>update: origDictionary with: newDictionary collection: aString (UpdateOperation collection: aString id: self nextRequestID stream: stream originalObject: origDictionary newObject: newDictionary) write But there is no room for "options" I tried to do it with commands but wasn't able to figure out how. In MongoShell, db.runCommand({ "update":"Message", "query":{}, "updates": [{"$set": {"READ":true} }], "options": {"multi":true} }) gives me "missing q parameter" Anyone knowing how to do this? I've also done this code: | query what | query := { } asDictionary. what := { 'READ' -> true } asDictionary. Mapless currentRepository database beLogging. (Mapless currentRepository collection: Message) "<<- basically one gets a Mongoclient doing the updata:with:" update: query with: {'$set' -> what } asDictionary. Thanks for any help :-) Phil
