Cloning the records using clone method

Apex Class

How to clone records based on related list of custom object records ?

A custom object (DataLoadTest__c) is created with fields as name,city,country and phone.

A controller fetches the vf pages selected record.

public with sharing class CloneTestingRecordClass {

    public PageReference clonedRec()

{

        DataLoadTest__c selectedRecord = [select Id,name,city__c,country__c,phone__c from DataLoadTest__c where id=:rId];

        dataLoadtest__c lstnew = selectedRecord.clone(false);

        insert lstnew;

       

        pagereference ref = new pagereference('/apex/cloneRecordTesting');

        ref.setredirect(true);

        return ref;

    }

    public String rId{get;set;}

   

    List<DataLoadTest__c> lstdlt = new List<DataLoadTest__c>();

    public List<DataLoadTest__c> getRecords() {

        lstdlt = [select Id,name,city__c,country__c,phone__c from DataloadTest__c];

        return lstdlt;

    }

}

A Visualforce page displaying all the objects records and on selection of the command link, we pass the records id through apex:param.
