Cattle seek advice ContentResolver.delete () inside Parameter Meaning

API: ContentResolver.delete (Uri url, String where, String [] selectionArgs)

To operate a contentprovider inside the database, delete a single record no problem. Then I want to remove the id> 5 of the N records? ?

Uri uri = Uri.parse ("content :/ / com.example.android_contentprovider.myContentProvider / person");

delete (url, "id>?", new String [] {"5"}); was an error! ! ! Did you have to delete the entire table has two parameters behind Did you pass null How can what use is it?
