I just asked this the other day (and got the answer). These iterators can be classes implementing Iterable interface or standard apex data strucutres like list. Traditional For Loop. 1. query method should be used in instances where you are wanting to do a dynamic runtime SOQL query for your code. In this case as iterator is defined as Iterator<sObject>, hence return type should be sObject (not List<sObject> as you declared in your code). Yes but the Batch Apex section clearly says: If you use a QueryLocator object, the governor limit for the total number of records retrieved by SOQL queries is bypassed. By default, the values will be evenly spaced by 1 but this can be set with the step argument. wb,lb)+torch. yes it will insert 60K record but it happens through batch by batch. First of all,you should not be running a SOQL query inside the for loop,that is not the best practice. 8.
