Hi All, 

i have wrote a batch class ,But looks i am going Wrong Smewer , it shows 
 no viable alternative at character ' ' 


my code looks like :

global class RMABatchProcess implements Database.Batchable<sObject>{

     public List<RMA_Staging__c> RMAStgobj = new List<RMA_Staging__c>();
     public List<RMA_Staging_Lines__c> RMAStgLine = new List<RMA_Staging_Lines__c>();
     
    
     global RMABatchProcess() {            
        this.query = 'SELECT Id,Name,RecordTypeId,SM_Catalyst_RMA_Reason__c,SVMXC__Address_Type__c,SVMXC__Company__r.Name,SVMXC__Destination_City__c,SVMXC__Destination_Country__c,SVMXC__Destination_Location__r.Name,SVMXC__Destination_State__c,SVMXC__Destination_Street__c,SVMXC__Destination_Zip__c,SVMXC__Expected_Delivery_Date__c,SVMXC__Order_Status__c,SVMXC__Order_Type__c,SVMXC__Parts_Request__r.Name,SVMXC__Priority__c,SVMXC__RMA_Type__c,SVMXC__Service_Engineer__r.Name,SVMXC__Service_Order__r.Name,SVMXC__Source_City__c,SVMXC__Source_Country__c,SVMXC__Source_Location__r.Name,SVMXC__Source_State__c,(SELECT Id,Name,RecordTypeId,SVMXC__Actual_Quantity2__c,SVMXC__Actual_Receipt_Date__c,SVMXC__Disposition__c,SVMXC__Expected_Condition__c,SVMXC__Expected_Quantity2__c,SVMXC__Line_Status__c,SVMXC__Parts_Request_Line__r.Name,SVMXC__Product__r.Name,SVMXC__RMA_Shipment_Order__r.Name,SVMXC__Serial_Number__c,SVMXC__Service_Engineer__r.Name,SVMXC__Service_Order__r.Name FROM SVMXC__RMA_Shipment_Line__r WHERE SVMXC__Line_Status__c = \'Open\'),SVMXC__Source_Street__c,SVMXC__Source_Zip__c FROM SVMXC__RMA_Shipment_Order__c WHERE SVMXC__Order_Status__c = \'Open\' and RecordtypeId= \'012410000004qj3\'';
