hi..need a help in query...oh batch class
Error is : unexpected token: ')' 
We would like to move leads currently in the Working or Busy status that do not have completed tasks in the last 30 days to the ABC status.

• Lead Status = Working, Busy
• Last Activity Date < Today – 30

We want to scheduale a batch class daily basis...here is the code..

global class Leadinactiveflow implements Database.Batchable<SObject>

{

 global Database.Querylocator start (Database.BatchableContext BC)
  {
         
   String query = 'SELECT Id, Status, LastActivityDate ,(select id, createdDate,status from Tasks )From Lead WHERE Status in (\'Working\', \'Busy\')  AND  (Today() - LastActivityDate) > 30';
   System.debug(query);

      return Database.getQueryLocator(query);          

  }
  global void execute (Database.BatchableContext BC, List <Lead> scope)

  {

   List<Lead> listLead = new List<Lead>();

    for(Lead l : scope)
     {
      
         l.Status = 'ABC';     

      listLead.add(l);

      }

   
         if(!listLead.isEmpty()){
            update listLead;
        } 

  } 

global void finish (Database.BatchableContext BC)

{

}

}

Schedulable class is :
 

global with sharing class SchedulerForBatchApex implements Schedulable

{
    global void execute(SchedulableContext sc)        

  {
      Leadinactiveflow b = new Leadinactiveflow();
      ID BatchID = Database.executeBatch(new Leadinactiveflow(), 200);
  }

Public static void SchedulerMethod() 

    {
    string con_exp='0 0 1 * * ?';

    System.schedule('LeadinactiveflowTest', con_exp, new SchedulerForBatchApex());
                                     
    }   

}
