Apex Code:
global class batchAccountUpdate implements Database.Batchable<sObject> {
global class batchAccountUpdate implements Database.Batchable<sObject> {
global Database.QueryLocator start( Database.BatchableContext BC ) {
String query = ‘SELECT Id,Name FROM Account’;
return Database.getQueryLocator( query );
}
global void execute( Database.BatchableContext BC, List< Account > scope ) {
for ( Account a : scope ) {
a.Name = a.Name + ‘Updated’;
}
update scope;
}
global void finish( Database.BatchableContext BC ) {
}
}
Run the batch apex for testing it in Developer Console.
Output:

Create another batch with below code
for(Account a : scope)
{
a.Name = a.Name.remove('Updated');
}
update scope;

Yes. You can do this. But check Salesforce documents for Apex Class version supported.
Hi Mahesh,
try this
global class AccountBatch_AC implements Database.Batchable{
global Database.QueryLocator start(Database.BatchableContext bc){
String strQuery='SELECT id,name FROM Account';
return Database.getQueryLocator(strQuery);
}
global void execute(Database.BatchableContext bc,List lstAccObj){
for(Account accObj:lstAccObj){
accObj.name='Mr'+accObj.name;
lstAccObj.add(accObj);
}
update lstAccObj;
}
global void finish(Database.BatchableContext bc){}
Lol !
The code is identical with the one posted by Mahesh.
