How to get Record Owner ID from record ID?

Question

I want to get the owner id/ user id of current record.

for this what I know, we have to do 2 things. 1) First we have to fetch record ID from URL by using

ApexPages.CurrentPage().getparameters().get('id');

2) We can fetch owner ID by using this record ID.

If I am correct then how to fetch record owner ID by using record ID?

Answer 1

Yes you are correct .Just putting amswer into programmatic way

First get the Id in URL parameter and then on page fetch using

Id recId=ApexPages.CurrentPage().getparameters().get('id');

Secondly use Select statement and get the ownerId(Assuming object is Account)

 ID ownerId=[Select Id,ownerId from Account where Id=:recId].ownerId

Update:

After the comments looks like this has to be dynamic solution

id testid=ApexPages.CurrentPage().getparameters().get('id');
String objecttype=testid.getSobjectType().getDescribe().getName();
try{
    Sobject s=(Database.query('Select Id,ownerId from '+objecttype+' where Id=:testid LIMIT 1'));
    }
catch(exception e){
    }
    Id ownerid=(ID)s.get('ownerId');
