Dynamics CRM executing multiple requests c#

Question

I want to update a field of an account and I have the guid of account.

Can I update the field (for instance, address of the account) without retrieve request using an update request?

Here my code

Entity account= _service.Retrieve("account", Guid.Parse(accountGuid), new ColumnSet(true));
account.Attributes["new_password"] = password;
_service.Update(account);

Is it possible to use ExecuteMultipleRequest in this scenario?

Answer 1

If you have the Id of the record, yes, it can be done without a Retrieve.

Just write

Entity accountToUpdate = new Entity("account");
accountToUpdate.Id = Guid.Parse(accountGuid);
accountToUpdate["new_password"] = password;
_service.Update(accountToUpdate);

ExecuteMultipleRequest is used to batch multiple request at once, in that case you need to create first an UpdateRequest and add to the collection first, you can google for examples.
