want to send mail in finish method of batch apex

Hi 

I have a requirement . in this i have to insert and update account records . 

If account filed failed to insert then status field value will be IF .

If account field failed to update then status field value will be UF .

After batch apex execute there are records which will be failed to insert and failed to update .

I want to send mail to the owner that these records are failed due to duplicate value .

How to send this mail to owner in the finish method of batch apex .

    Hi,

    Use Database Class methods to do partial update. With Database.SaveResult[], you will get the status of DML operation.

    Sample example here:

    // Create the list of sObjects to insert
    List<Account> acctList = new List<Account>();
    acctList.add(new Account(Name='Acme1'));
    acctList.add(new Account(Name='Acme2'));
    // DML statement
    Database.SaveResult[] srList = Database.insert(acctList, false);
    // Iterate through each returned result
    for (Database.SaveResult sr : srList) {
        if (sr.isSuccess()) {
            // Operation was successful, so get the ID of the record that was processed
            System.debug('Successfully inserted account. Account ID: ' + sr.getId());
        }
        else {
            // Operation failed, so get all errors                
            for(Database.Error err : sr.getErrors()) {
                System.debug('The following error has occurred.');                    
                System.debug(err.getStatusCode() + ': ' + err.getMessage());
                System.debug('Account fields that affected this error: ' + err.getFields());
            }
        }
    }

    Once you got the output,  you just have to send an email from the error block by using Messaging.SinglEmailMessage.

     

    Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
                String[] toAddresses = new String[] {email1, emaiol2};
                mail.setToAddresses(toAddresses);
                mail.setSubject('Batch Subject ' + a.Status);
                mail.setPlainTextBody('records processed ' + a.TotalJobItems +
               'with '+ a.NumberOfErrors + ' failures.');
                Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });

    Thanks

    Brahma
