Batch Class to delete opps whose closedate is last month

Hi, I am trying to write a batch class which will delete the opportunities whose CloseDate is last month and update checkbox in related account.

//Batch Class

global class DeleteOppsBatch implements Database.Batchable<SObject> {
    List<Account> newList = new List<Account>();
    global Database.QueryLocator start (Database.BatchableContext BC) {
        return Database.getQueryLocator([Select Id, DeletedOpp__c, (SELECT Id, CloseDate FROM Opportunities WHERE CloseDate = LAST_N_DAYS:30) FROM Account]);
    }
    global void execute(Database.BatchableContext BC, List<Account> accList) {
        for(Account acc : accList) {
            acc.DeletedOpp__c = TRUE;
            newList.add(acc);
        }
        //update newList;
    }
    global void finish(Database.BatchableContext BC) {
        System.debug('listsize:'+newList.size());
        delete newList;
    }
}

I didn't understand why this class is not working. Can someone help me achieve this functionality.

Thanks in advance.

Hii SaiVineeth
try Below code
  
Global class DeleteOppsBatch implements Database.Batchable<SObject> {
    
    global Database.QueryLocator start (Database.BatchableContext BC) {
        return Database.getQueryLocator([SELECT Id, CloseDate FROM Opportunities WHERE CloseDate < LAST_N_DAYS:30) FROM Account]); 
        }
    global void execute(Database.BatchableContext BC, List<Opportunity> lstopp) {

        List<Account> updateAccounts = new List<Account>();
        List<Opportunity> deleteOpps = new List<Opportunity>();
        Set<id> setofAccId = New Set<Id>();
        for(opportunity objopp : lstopp) {
            if(objopp.AccountId != null)
            {
                deleteOpps.addall(objopp);
                setofAccId(objopp.AccountId); 
            }
        }
        for(Account objacc :[Select id,Name,DeletedOpp__c from Account where Id In:setofAccId]){
            objacc.DeletedOpp__c = true;
            updateAccounts.add(objacc);
        }
        if(deleteOpps.size() > 0){
             Delete deleteOpps;
        }
        if (updateAccounts.size() > 0) {
            Update updateAccounts;
        }
      
    }
    global void finish(Database.BatchableContext BC) {
        System.debug('listsize:'+newList.size());
        
    }
}

With Batch class, Delete operation should be exeucted in Execute method.  You may refer the code below.



Global class DeleteOppsBatch implements Database.Batchable<SObject> {
    
    global Database.QueryLocator start (Database.BatchableContext BC) {
        return Database.getQueryLocator([Select Id, DeletedOpp__c, (SELECT Id, CloseDate FROM Opportunities WHERE CloseDate < LAST_N_DAYS:30) FROM Account]);      //it should be using < mark as you want closedate older than 30 days.
    }
    global void execute(Database.BatchableContext BC, List<Account> accList) {

        List<Account> updateAccounts = new List<Account>();
        List<Opportunity> deleteOpps = new List<Opportunity>();
        for(Account acc : accList) {
            if(acc.Opportunities.size() > 0)
            {
                deleteOpps.addall(acc.Opportunities);
                acc.DeletedOpp__c = TRUE;
                updateAccounts.add(acc);
            }
        }

        if (updateAccounts.size() > 0) {
            Delete deleteOpps;
            Update updateAccounts;
        }
      
    }
    global void finish(Database.BatchableContext BC) {
        System.debug('listsize:'+newList.size());
        
    }
}

Thanks for your response. Now I was able to run the batch class.
