How to use save points in apex class while saving data and how to implement it?

Hi Naman,

Try using this approach, hope this will help you:

Account a = new Account(Name = 'Abc');

insert a;

System.assertEquals(null, [SELECT AccountNumber FROM Account WHERE Id = :a.Id].
AccountNumber);

// Create a savepoint while AccountNumber is null
Savepoint sp = Database.setSavepoint();

// Change the account number
a.AccountNumber = '123';
update a;
System.assertEquals('123', [SELECT AccountNumber FROM Account WHERE Id = :a.Id].
AccountNumber);

// Rollback to the previous null value
Database.rollback(sp);
System.assertEquals(null, [SELECT AccountNumber FROM Account WHERE Id = :a.Id].
AccountNumber);

Thanks
