Apex batch execute method not being called

Question

I have the below batch code

global class BatchClassAccountSched implements Database.Batchable<SObject>, Database.AllowsCallouts, Schedulable {

global Database.Querylocator start(Database.BatchableContext BC) {
    String query = '';
    if(Test.isRunningTest()){
            query = 'SELECT ShippingCity,ShippingCountry,ShippingPostalCode,ShippingState,ShippingStreet FROM Account WHERE Location__Latitude__s = null and Location__Longitude__s = null and ShippingStreet != null and ShippingCity != null and ShippingCountry != null and ShippingPostalCode != null and ShippingState != null and Owner.CEE_Sales_Group_Code__c != null limit 100';            
           system.debug('####query'+query);
        }
      else{
          query = 'SELECT ShippingCity,ShippingCountry,ShippingPostalCode,ShippingState,ShippingStreet FROM Account WHERE Location__Latitude__s = null and Location__Longitude__s = null LIMIT 100';
          system.debug('@@@@ACCOUNT'+query);
      }
      system.debug('boh: '+Database.getQueryLocator(query));
       return Database.getQueryLocator(query);
}  

global void execute(Database.BatchableContext bc, List<Account> scope) {
    system.debug('in execute');

 // create an address string
        List<Account> newListAcc = new List<Account>();
        for(Account accountNew : scope){

            //stuff with a try-catch 

       } 
       system.debug('*****NUOVA LISTA ACCOUNT : ' + newListAcc);
       update newListAcc;
       system.debug('*****@@@'+newListAcc);
       system.debug('*****@@@'+newListAcc.size());


}

/*global void execute(SchedulableContext sc) {
        Database.executeBatch(this, 100);
    }*/

global void execute(SchedulableContext sc) {
    system.debug('prima');
    Id batchJobId = Database.executeBatch(new BatchClassAccountSched());
    system.debug('dopo');
}

global void finish(Database.BatchableContext BC){
   }


}

but when i call it with

Database.executeBatch(new BatchClassAccountSched());

I do not see any debug from the execute method... why do you think this happen? I have tried to see the logs and they stop here. What is going on?

Answer 1

Execute runs in a different transaction, so it will be in a different log. You should have three logs altogether, one for start, one for execute, and one for finish. It shows that 100 rows were selected (so, one iteration, or execution, should fire), so you need to find the next log after that one. If the LIMIT were higher, or omitted entirely, you could have many logs generated from running that command, depending on the volume of accounts that met your criteria.

Answer 2

Try -

global void execute(Database.BatchableContext bc, **List<sObject>** scope) 

intead of -

global void execute(Database.BatchableContext bc, List<Account> scope)
