Hi,

You can achieve the above scenario by using Batch Apex and Schedule Apex. Please check the below sample code.

Batch Class
  
global class BatchWishes implements Database.Batchable<Employee__c> {
     global Iterable<employee__c> start(Database.BatchableContext bc){
     list<employee__c> sq=[select name,empname__c ,Email_Id__c from employee__c where Date_of_Birth__c=today];
    return sq;
    }
   global  void execute(Database.BatchableContext bc, List<employee__c> lst)
      {
list<Messaging.SingleEmailMessage> mail = new list<Messaging.SingleEmailMessage>();

        for(employee__c e: lst)
        {
         Messaging.SingleEmailMessage maileach = new Messaging.SingleEmailMessage();
         list<string> toadd=new list<string>();
         toadd.add(e.Email_Id__c );
          maileach.settoaddresses(toadd);
          maileach.setsubject('birthday wishes');
          maileach.setplaintextbody('happy birthday '+e.empname__c);
          mail.add(maileach);
        }
      
    Messaging.SendEmailResult[]  result  =Messaging.sendEmail( mail);
     
    } 
   global  void finish(Database.BatchableContext sc) 
   
    {
      system.debug(sc);
    
    }
}

Schedule class
  
global class BirthdayNameOptions implements Schedulable{

global   void execute(SchedulableContext dc){
//batch class name   
 BatchWishes bth=new BatchWishes ();
    Database.executeBatch(bth,20);
    }
}

You can schedule a batch which runs at 12 am every day.Please follow the below steps for Schedule a batch class.

Go to Setup--->Develop--->Apex classes--->Schedule Apex

Here you can set the time.Please check the below screenshot.

global class BirthdayNotificationBatch Implements Database.Batchable <sObject> {
    global Database.queryLocator start(Database.BatchableContext bc) {
        Date tody = system.today();
        String SOQL = 'SELECT Id, Name, Email__c FROM Employee__c WHERE DAY_IN_MONTH(Date_of_Birth__c) = ' + 
                      tody.day() +  ' AND CALENDAR_MONTH(Date_of_Birth__c) = ' + tody.month();
        return Database.getQueryLocator(SOQL);
    }

    global void execute(Database.BatchableContext bc, List<Employee__c> listEmployee) {
        List<Messaging.SingleEmailMessage> mailList = new List<Messaging.SingleEmailMessage>();
        for(Employee__c m : listEmployee) {
            List<String> toAddresses = new List<String>{m.Email__c};           
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
            mail.setToAddresses(toAddresses);
            mail.setSubject('Happy Birthday');
            String messageBody = '<html><body>Hi ' + m.Name + ',<br/>Happy Birthday.<br/>Many More Happy '+
                                 'Returns of the day.<br/><br/><b>Regards,</b><br/>Admin</body></html>';
            mail.setHtmlBody(messageBody); 
            mailList.add(mail);          
        } 
        Messaging.sendEmail(mailList);        
    }

Hi Jyosthna, 
list<employee__c> sq=[select name,empname__c ,Email_Id__c from employee__c where Date_of_Birth__c=today];
In the above query 'Date_of_Birth__c' can never be equal to 'taday' as it is a past date. 
list<employee__c> sq=[select name,empname__c ,Email_Id__c from employee__c where Date_of_Birth__c.day()=date.today.day() AND Date_of_Birth__c.month()=date.today.month()];
Thanks,

Hi,

Below is the code that you can use for sending email on your employee bithday and schedule it every day as mentioned by Nayana K .


global class WishOnBirthdayBatch implements Database.Batchable<sObject> , schedulable
{
    global void execute(SchedulableContext ctx) 
    {
      WishOnBirthdayBatch batch = new WishOnBirthdayBatch();
      Database.executeBatch(batch,20);
    }
    global Database.QueryLocator start(Database.BatchableContext bc)
    {    
        Integer day= date.today().day();
        Integer mon = date.today().month();
        String EmpList= 'select name, Employees_Name__c , Wish_me_on__c,Email__c from Company__c where DAY_IN_MONTH(Wish_me_on__c) = : day AND CALENDAR_MONTH(Wish_me_on__c) = : mon limit 100';
        Return Database.getQueryLocator(EmpList);
    }
    global  void execute(Database.BatchableContext bc, List<Company__c> lst)
    {
        list<Messaging.SingleEmailMessage> mail = new list<Messaging.SingleEmailMessage>();

        for(Company__c comp: lst)
        {
            Messaging.SingleEmailMessage mailToEmployees = new Messaging.SingleEmailMessage();
            list<string> toadd=new list<string>();
            toadd.add(comp.Email__c );
            mailToEmployees.settoaddresses(toadd);
            mailToEmployees.setsubject('birthday wishes');
            mailToEmployees.setplaintextbody('happy birthday '+comp.Employees_Name__c);
            mail.add(mailToEmployees);
        }
      
        Messaging.SendEmailResult[]  result  = Messaging.sendEmail( mail);
         System.debug(result);
