The problem is the implementation of execute method. It has wrong parameters. Check out this code:
global void execute(Database.BatchableContext bc,List<opportunity> optList){ } // Should be global void execute(Database.BatchableContext BC, List<sObject> scope) { List<Opportunity> optList = (List<Opportunity>) scope; // do your things here }Regards.
I tried the same code but I make only make a change in the query and it works fine.
String query='Select id,name,stagename,CloseDate from opportunity WHERE CreatedDate = THIS_MONTH';
In your code in your query you have written "name.stagename" that is incorrect.
I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
