A way to produce an empty Id is with sObject.put(String fieldname, String value) method. Try the following in exec anonymous: Account s = new Account(); System.debug(s.Id); if(s.Id == null) System.debug('check for null ok.'); s.put('Id',''); if(s.Id == null) System.debug('check for null ok.'); if(String.isBlank(s.Id)) System.debug('check for isBlank ok.'); System.debug(s.Id); | |
