Hi,

I am trying to maintain count in batch apex. i am using database.stateful.. but the count is not being maintained... below is the code:-

global class Batch_ConvertLead implements Database.Batchable<sObject>, Database.Stateful {

    public String query;
    public String rank = 'Ghost App';
  global integer Count;

    global database.querylocator start(Database.BatchableContext BC){
        query = 'SELECT Id, AccountId__c FROM Lead WHERE isconverted = false AND Rank__c = :rank and AccountId__c != null';
        return Database.getQueryLocator(query); 
 Count=0;
    }

    global void execute(Database.BatchableContext BC, List<sObject> scope){

        List<Lead> leadsToConvert = new List<Lead>();
        list<Database.LeadConvert> leadConverts = new list<Database.LeadConvert>();

        for(sObject leadconv : scope){
            leadsToConvert.add((Lead) leadconv);
        } 
    
        for(lead le :leadsToConvert){
        
            for(Integer i=1;i<leadsToConvert.size();i++){
            Database.LeadConvert lc = new database.LeadConvert();
            lc.setLeadId(le.Id);
            lc.setConvertedStatus('Converted');
            lc.setDoNotCreateOpportunity(true);
            lc.setAccountId(le.AccountId__c);
            leadConverts.add(lc);
            Count = count + 1;
            
            }
        }
        Database.LeadConvertResult[] lcrList = Database.convertLead(leadconverts, true);
        for(Database.LeadConvertResult result : lcrlist) {
            if(!result.isSuccess()) {
                System.debug(result.getErrors());
            }
        }
    }

    global void finish(Database.BatchableContext BC){
        AsyncApexJob asyJob = [SELECT Id,Status,CompletedDate,TotalJobItems, NumberOfErrors, JobItemsProcessed,CreatedBy.Email FROM AsyncApexJob WHERE Id = :BC.getJobId()];
        //String[] toAddresses = new String[] {system.label.Ireland_EmailD_BatchApex}; 
        String[] toAddresses = new String[] {'janardhanan.jagadeesan@hotchalk.com'}; 
        Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
        mail.setToAddresses(toAddresses);
        String subject = 'Lead Convert Batch';
        mail.setSubject(subject+ '<' + asyJob.status + '>');
        mail.setPlainTextBody('The batch Apex job processed ' + asyJob.TotalJobItems + ' batches with a total of ' + count + ' records with '+ asyJob.NumberOfErrors + ' failures.');
        Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail }); 
    }

}
