Get the inserted record id in a upsert call?

you can use a Set of Id and before upsert dml iterate over list and collect all ids

`set accIds = new set();
for(Account accObj : accountList){
if(accObj.Id != null) accIds.add(accObj.Id);
}
upsert accountList Eid__c;

for(Account insertedAccount : accountList){
if(!accIds.contains(insertedAccount.Id))
{
system.debug('*** Id = ' + insertedAccount.id);
}
}`
