How to insert owner name in Account?

Question

I have tried inserting a new record with ownerId and also with ownerName.But using "Ownername" shows the below error

  Account acc=new Account(Name='nEW',OwnerId='00528000001IpTb');
        insert acc;
        Account acc1=new Account(Name='nEW',Account__r.owner.firstname='gSS');
        insert acc;

Invalid field initializer: Account__r.owner.firstname

How can I use OwnerName instead of OwnerId?Or is there any work around?

Answer 1

Your problem is on this line

Account acc1=new Account(Name='nEW',Account__r.owner.firstname='gSS');

There is no relationship account__r.owner.firstname

The relationship is account.owner.somefieldonUser

and even so, when you insert an sobject, you can only instantiate fields directly on that sobject

so what you need is:

Account acc1=new Account(Name='nEW',ownerId = someExpressionThatderivesAnOwnerId);  

Once the Account has an ownerId, you can query the Account to discover things about the owner:

[select id, owner.firstname, owner.lastname, owner.alias from Account where someWhereExpression]
